Abstract

PURPOSE:To efficiently obtain an alginic acid oligosaccharide useful for increasing yield of agricultural crops, by reacting a substance containing alginic acid (salt) with alginate lyase and terminating the reaction when the reaction solution attains a given absorbance. CONSTITUTION:Alteromonas sp. LB 102 strain (FERM P-9218) which is a microorganism of the genus Alteromonas is cultivated and the resultant culture is extracted to provide alginate lyase (A) having about 7 optimum pH and about 40 deg.C optimum temperature. The resultant enzyme (A) in an amount of 100-4,000 units based on 1g sodium alginate is then added to a solution (B) prepared by adding 100pts. water to 1-5pts. sodium alginate and adjusting the pH to about 7 and reacted at about 40 deg.C for 24-48hr. When the absorbance at 230nm (E1cm<1>) attains 30-60, the reaction is terminated to adjust the pH of the reaction solution to 1-4. Heat treatment is carried out at 100-120 deg.C for 15-180min to produce the aimed alginic acid oligosaccharide.

(2) Alginic acid is a polysaccharide consisting of mannuronic acid and guluronic acid. When this is decomposed by alginate lyase, a wide variety of oligosaccharides are produced as the decomposition progresses, and finally the constituent sugar component, mannuron, is produced. It is broken down into acid and guluronic acid. However, since these monosaccharides do not have a plant growth promoting effect, it is necessary to establish optimal decomposition conditions for alginic acid from the viewpoint of plant growth effects.

In order to solve these problems, the present inventors conducted intensive studies and discovered that oyster gastrointestinal enzymes can be used as an inexpensive enzyme source and that microorganisms newly isolated from seawater as brown algae lytic bacteria can be used. In order to efficiently produce alginate lyase, and furthermore, in the process of making alginate lyase act on alginic acid to produce alginate oligosaccharide, it is necessary to maintain a certain level of change in the absorbance of 230na+ of the reaction solution itself and the plant growth promoting activity of the reaction product. The present inventors have discovered that there is a relationship between the two, and that a reaction product with high plant growth promoting activity can be obtained by specifying the range of absorbance and stopping the reaction, leading to the completion of the present invention.
