Hereinafter, the present invention will be described in detail through Examples. However, these Examples are only to illustrate the present invention, and a scope of the present invention is not limited to these Examples.
Example 1: Isolation of Strain Oxidizing Ammonia and
Nitrous Acid (1) Preparation of Sample and Isolation of Strain
Strains derived from good fermented-soybean products such as soy bean paste, fermented soy bean, soy sauce, or the like, which are traditional Korean food were isolated as samples. The samples were spread on BHI agar medium (Difco, USA) with 3% NaCl and then cultured at 37°C for 24 hours. Strains isolated from each of the samples were grouped depending on results obtained by observing colonies.
The isolated colony was re-isolated by a method of transferring and culturing the selected colony in a new medium three times, and the purely cultured strains were put into a medium containing 20% glycerol and preserved at -70°C or less. (2) Evaluation of Oxidizing Ammonia and Nitrous Acid
In order to primarily isolate strains oxidizing ammonia and nitrous acid, which are main causes of water pollution, oxidation of ammonia and nitrous acid was evaluated.
In order to evaluate oxidation of ammonia, an ion medium containing ammonia ((NH4),SOs 4.95g/L, K,HPO, 8.82g/L,
MgSO4 (1M solution) 1.1ml/L, CaCl,(1M solution) 0.3ml/L,
FeSO4(30mM solution) 0.5ml/L, CuSO,(50mM solution) 0.04ml/L,
NaH,POs 0.7g/L, 5% (W/V) NayC0Os3 anhydrous 12ml/L) and an ionic medium containing nitrous acid (CaCl, 0.01g/L,
MgSO4- 7TH20 0.1g/L, EDTA 1.4mg/L, FeSO4* 7H0 5mg/L, H2S04 0.5
W/L, NaMoO4 + 2H,0 0.05mg/L, MnCl, * 4H,0 0.1lmg/L, CoCl;* 6H20 0.00Img/L, ZnSO4* 7H,0 0.05mg/L, CuS04 :5H,0 0.01lmg/L, NaNO, 0.21g/L, KHPO, 0.3mg/L) were prepared. The isolated strains (0.01%) were each inoculated into 5ml of two media prepared as described above and then cultured at 30°C for 14 days. After the cultured solutions were centrifuged and
Iml of each of the culture supernatants was extracted, an indicator (sulanilic acid, N, N-Dimethyl-l-naphylamine) allowing a color to be changed when nitrous acid exists was added by 1004. The culture supernatant to which the indicator was added was reacted at 25°C for 10 minutes, and a —————————————————————————————— rr 16 whether the color changed or not was visually observed. In the case in which nitrous acid existed or was formed, the color of the culture solution was changed into dark purple, and in the case in which nitrous acid did not exist or was consumed, a change of the color was not observed.
About 1000 isolated strains were evaluated, 7 strains oxidizing both ammonia and nitrous acid, 2 strains having excellent ammonia decomposition efficacy, and 1 strain having nitrous acid decomposition efficacy were selected as shown in Table 1. [Table 1]

Number Ammonia Nitrous Acid
Example 2: In vitro Evaluation of Oxidizing Ammonia and Nitrous Acid (1) Quantitative Evaluation of Ammonia for Primarily
Selected Strain
In order to evaluate an effect of decreasing ammonia depending on oxidation of ammonia by the primarily isolated strains, a consumption amount of ammonia was quantified in a medium containing ammonia.
The 10 primarily isolated strains (0.1%) were each inoculated into a BHI liquid medium and then cultured at 37°C and 200 rpm for 15 hours, thereby activating the strains. The activated strains (1%) were each inoculated into a medium containing ammonia ((NHg),S0; 0.5g/L, NaH,PO, 13.5g/L, KpHPO, 0.7g/L, MgSO4-° 7H,0 0.1g/L, CaCl," 2H,0 0.18g/L, NaHCO; 0.5g/L, FeCls- 6H,O 0.014g/L, glucose 0.5g/L) and cultured at 37°C and 200 rpm. During the culturing process, culture solutions cultured for 6, 12, 24, and 36 hours were extracted and centrifuged. Then, only culture supernatants were recovered. An amount of ammonia remaining in the recovered culture supernatant was quantified.
As a result, it was confirmed that a content of ammonia in the culture supernatant was decreased for all of the 10 isolated strains as shown in FIG. 1. Particularly, in the cases of strains Nos. 283, 296, 303, and 396, the content of ammonia was rapidly decreased after 6 hours, corresponding to an initial culture step. In order to confirm that ammonia was oxidized and formed nitrous acid, the indicator allowing a color change when nitrous acid exists was added and the color reaction was observed. As a result, a change in the color was not observed in an initial stepe, but in each of the samples extracted when the culture was terminated, colors of all of the culture
Supernatants were changed into dark purple. Therefore, it is appreciated that all of the primarily isolated strains oxidize ammonia into nitrous acid. (2) Quantitative Evaluation of Nitrous Acid for
Primarily Isolated Strains.
In order to evaluate an effect of decreasing nitrous acid depending on oxidation of nitrous acid by the primarily isolated strains, a consumption amount of nitrous acid was quantified in a medium containing nitrous acid.
The 10 primarily isolated strains (0.1%) were each inoculated into a BHI liquid medium and then cultured at 37°C and 200 rpm for 15 hours, thereby activating the strains. The activated strains (1%) were each inoculated into a medium containing nitrous acid (NaNO; 0.5g/L, NaH,PO, 13.5g/L, KHPOs; 0.7g/L, MgSO,+7H,0 0.1g/L, CaCl, * 2H,0 0.18g/L, NaHCO; 0.5g/L, FeCls* 6H,0 0.014g/L, glucose 0.5g/L) and cultured at 37°C and 200 rpm. During the culturing process, culture solutions cultured for 6, 9, 12, 24, and 30 hours were extracted and centrifuged. Then, only culture supernatants were recovered. An amount of nitrous acid remaining in the recovered culture supernatant was quantified.
As a result, it may be confirmed that a content of nitrous acid in the culture supernatant was decreased for ¢5 all of the 10 selected strains as shown in FIG. 2.
Particularly, in the cases of strain Nos. 102, 109, 251,
NOVEL SEPARATED BACILLUS LICHENIFORMIS AND PROBIQTLICS | Lins
USING SAME
The present invention relates to a novel probiotics and a use thereof.
An aquaculture industry has become an important economic means in various countries, and consequently, generation of diseases in farmed fish has a large influence on economic development (Jose Luis Balcazar et al.,
Veter.Microbio., 114(2006):173-186).
In general, in order to treat diseases generated in farmed fish and improve water quality, antibiotics, antimicrobial agents, chemicals have been used. However due to excessive uses thereof, problems such as an increase of resistant bacteria, residues in the farmed fish, water pollution in the surroundings, and the like, were generated, therefore a use thereof has been restricted. In addition, as the people’s interest in whether or not the antibiotics have used while aquaculturing was increased, an alternative material such as an organic acid, probiotics, a non- specific immune stimulator, a natural material, or the like, has been urgently developed in order to basically block the antibiotics (Fish Disease Diagnosis and Treatment
253, and 268, the content of nitrous acid was rapidly decreased after 6 hours, corresponding to an initial culture step. In order to judge whether or not nitrous acid was oxidized, the indicator allowing a color change when nitrous acid exists was added, and the color reaction was observed. As a result, a dark purple color was observed in initial medium, but in each of the samples extracted when the culture was terminated, a color of the culture supernatant was not changed. Therefore, it is appreciated that the primarily isolated strains oxidized nitrous acid, so there was no nitrous acid. (3) Evaluation of Growth Capacity
As a water quality environment, aerobic, facultative anaerobic, and anaerobic conditions co-exist, and particularly, since an anammox process (process in which ammonia is oxidized into nitric acid under anaerobic condition) proceeds under the anaerobic condition, it is an important that the isolated strains can grow under various conditions. Therefore, growth capacity of the 10 primarily isolated strains was evaluated under facultative anaerobic and anaerobic conditions.
The 10 primarily isolated strains(0.1%) were each inoculated into a BHI liquid medium, and then cultured at 37°C under the facultative anaerobic and anaerobic conditions for 24 hours. Most of the isolated strains grew under both of the facultative anaerobic and anaerobic conditions, and particularly, in the cases of strain Nos. 253 and 268, growth capacity under the anaerobic condition was excellent, and in the case of strain No. 283, growth capacity under the facultative anaerobic condition was most excellent (FIG. 3). Therefore, strain Nos. 253, 268, and 283 having excellent growth capacity under facultative anaerobic and anaerobic conditions were secondarily isolated. (4) Evaluation of Salt Resistance
In order to evaluate an activity of the strain in fresh water and sea water, growth capacity of the secondarily isolated strains was evaluated in a medium containing sodium chloride.
The three isolated candidate strains (0.1%) were each inoculated into BHI liquid media containing 0%, 3%, 5%, and 10% sodium chloride and cultured at 37°C and 200 rpm.
During the culture, each of the samples cultured for 8, 10, and 22 hours was extracted, and absorbance thereof was measured.
As a result, it was confirmed that as shown in FIG. 4, all of the three strains grew in the medium containing 3% sodium chloride. Particularly, in the case of strain No. 283, growth capacity in the medium containing 5% sodium chloride was excellent as compared to other strains.
Therefore, it is appreciated that the three secondarily isolated strains, strains Nos. 253, 268, and 283, may be applied under the sea water condition as well as the fresh water condition.
Example 3: In vivo Evaluation and Final Isolation of
Strains
Evaluation of water quality improvement capacity of the 3 secondarily isolated strains was performed in a fishfarm of young flatfish. The young flatfish were fed with a commercial feed for satiation and randomly distributed in experimental water tanks (64L). After distributing experimental fish, farming water in all of the experimental water tanks were all recovered. Then 50ml of the farming water was sampled in each of the water tanks after 0, 24, 48, 72, 92, and 102 hours. The secondarily selected strain was diluted to about 1x10° CFU/3ml and then put into the water tank every 24 hours for 5 days. In centrol groups, the same amount of sea water was put thereinto. After extracting a sample, a concentration of ammonia was analyzed, and the remained sea water sample after analysis was stored at -20°C. Thereafter, the stored sea water sample was used to analyze nitrite and nitrate.
For analyzing water quality, three categories of ammonia, nitrite, and nitrate were analyzed. The analysis was performed using a water quality analyzer (RQflex 10, Merck,
Germany) after reacting the sea water samples with a reagent of a kit, respectively.
As a result, after 72 hours, an effect of removing ammonia was shown (FIG. 5), and after 120 hours, the effect was further increased. After 140 hours, the flatfish started dying due to toxicity of ammonia in all of the water tanks. Among the three secondarily selected strains, the strains Nos. 253 and 283 had significantly high ammonia removing efficacy and also decreased mortality as compared to the control groups. Accordingly, it may be appreciated that the addition of strain oxidizing ammonia and nitrous acid to farming water (water used to farm fish (flatfish)) may increase a survival rate of the fish. Finally, the strain No. 283 having the excellent ammonia removing efficacy and growth capacity under facultative anaerobic and anaerobic conditions was isolated.
Example 4: Identification of Isolated Strain and
Investigation of Morphological and Biochemical Properties thereof (1) Investigation of Morphological and Biochemical
Properties
In order to identify the finally isolated strain, morphological and biochemical investigation was performed.
The morphological properties were as follows. The strain was a Gram-positive strain, and it was confirmed that the strain was a bacillus from an electron microscope photograph (FIG. 6). In order to analyze the biochemical properties, a sugar fermentation pattern of the strain was analyzed using API 50 CHB System (Biomerieux, France). [Table 2]

In order to accurately identify the strain, a molecular phylogenetic method using a DNA nucleotide sequence was performed. For nucleotide sequence analysis, a 16s rDNA gene was amplified using a polymerase chain reaction (PCR) premix (Bioneer, Korea), universal primers 27F (5'AGAGTTTGATCMTGGCTCAG3': SEQ ID No: 2) and 1492R
(3'GGYTACCTTGTTACGACTT3': SEQ ID No: 3). A total amount of reaction solution was set to 2044, and PCR was performed for 30cyclesat 94°C for 1 minute, 56°C for 1 minute, and 72°C for 1 minute. Then, the amplified DNA nucleotide sequence was analyzed. The analyzed 16s rDNA nucleotide sequence of the isolated strain is represented by a sequence of SEQ ID
No: 1. As a result of the analysis, the strain has homology of 96% with Bacillus licheniformis. Therefore, the isolated strain was named Bacillus licheniformis CJMPB283 and the novel strain according to the present invention was deposited in Korean Culture Center of Microorganisms (accession number KCCM11270P) on March 22, 2012.
Example 5: Analysis of Probiotic properties of
Bacillus licheniformis CJMPB283 (1) Digestive Enzyme Activity 1) Extraction of Crude Enzyme Solution
After culturing the isolated strain in a BHI liquid medium for 24 hours, a degree of decomposition of substrate was analyzed by using the culture solution as a crude enzyme solution and a medium containing a respective substrate corresponding to each of the enzymes. 2) Protease Activity
A yeast mold (YM) medium (Difco, USA) containing 2% skim milk (Sigma, USA) was prepared. After spotting 24 of each of the extracted crude enzyme solutions onto the substrate medium, a reaction was performed at 37°C for 15 hours, and then the enzyme activity was measured by a degree of formation of a clear zone. 3) Cellulase Activity
A YM medium containing 1% carboxyl methyl cellulose (CMC) substrate was prepared. After spotting 2ul of each of the extracted crude enzyme solutions onto each of the substrate media, a reaction was performed at 37°C for 15 hours. Thereafter, the reactant was dyed using 0.2% Congo red aqueous solution for 30 minutes, and then decolorized using 1M NaCl aqueous solution. The enzyme activity was measured by a degree of formation of a clear zone generated by decomposition of the substrate around the crude enzyme. 4) Amylase Activity
A YM medium containing 1% soluble starch substrate was prepared. After spotting 3ul of each of the extracted crude enzyme solutions onto the substrate medium, a reaction was performed at 37°C for 15 hours. The reactant was dyed using an aqueous solution containing 0.1% I, and 2% KI, and then the enzyme activity was measured by a degree of formation of a clear zone generated by decomposition of the substrate around the crude enzyme.
The finally selected Bacillus licheniformis CJIMPB283 strain had activities of the digestive enzymes (protease, amylase, and cellulase) as shown in Table 3. Particularly, the Bacillus licheniformis CJMPB283 strain had an excellent protease activity. [Table 3] [protease [| Amylase [| Cellulase] -: absence of activity, +: presence of Activity, ++:
So excellent activity, +++: significantly excellent activity (2) Endospore Formation Capacity
Bacillus forms endospores for survival under stress such as depletion of one or more of necessary nutrients, or the like. Since the endospores has resistance against extreme conditions such as ultraviolet rays, a high temperature, low temperature drying and high pressure, or the like, formation of the endospores 1s important for maintaining a survival rate of bacillus. Therefore, the
Bacillus licheniformis CJMPB283 was cultured for a long period, and endospore formation capacity thereof was confirmed.
The strain (0.1%) was inoculated into a BHI liquid medium and cultured at 37°C and 200 rpm for 24 and 48 hours.
The culture solution at each time was spread on a BHI agar medium, and a total cell was counted. In addition, a culture solution heat-treated at 95°C for 10 minutes was spread on a BHI agar medium, and the number of endospores was counted.
As shown in Table 4, it may be appreciated that when the Bacillus licheniformis CJMPB283 was cultured for 24 hours, an endospore formation rate was about 24.5%, and when the Bacillus licheniformis CJMPB283 was cultured for 48 hours, the endospore formation rate was 100%. The
Bacillus licheniformis CJMPB283 according to the present invention has an excellent endospore formation capacity when cultured for 48 hours or more, so that the Bacillus licheniformis CJMPB283 as probiotics may maintain a high survival rate. [Table 4] (CFU/ml) Rate (%)
The novel Bacillus licheniformis CJMPB283 according to the present invention has an excellent effect of producing digestive enzymes such as amylase, cellulase, and protease and excellent oxidation capacity for ammonia and nitrous acid, so that the novel Bacillus licheniformis CJMPB283 may have the probiotic effect and improve water quality when farming fish or crustacean. Therefore, the novel Bacillus licheniformis CJMPB283 may be used as the water depurative as well as the probiotics.
Countermeasures, Ministry of Oceans and Fisheries, 2001).
Probiotics are added to feed or additionally input to water in aquaculture industry. Recently, research on an effect of stimulating immunity against pathogen and improving water quality to alleviate disease by providing probiotics to farmed fish and shrimp has been actively conducted (Jigiu Li et al., Aquaculture 291(2009) 35-40).
The term “probiotics”, which has an etymological meaning opposed to antibiotics, is defined as a microbial material or microbial component assisting in a balance of intestinal microflora. Lactic acid bacteria such as
Lactobacillus, Bifidobacteria, and the like, are representative.
Bacillus used as probiotics, which is Gram-positive bacillus, forms endospores and has a unique shape among the bacteria used as probiotics. The Bacillus has excellent heat resistance as compared to Lactobacillus that does not form endospores. In addition, since Bacillus can survive at a low pH of stomach walls, most of the administrated
Bacillus may arrive at small intestine (Barbosa,T.M. et al.,
Appl. Environ. Microbiol., 71(2005)968-978; Spinosa, M. R. et al., Res. Microbiol., 151(2000) 361-368).
