である。[Detailed Description of the Invention] [Industrial Application Field] In order to stabilize enzyme activity and enable repeated use despite being water-soluble, enzymes are immersed in water by physical or chemical methods. A technology to insolubilize and use in the form of a solid catalyst has been developed, and is used in the industrial production of L-amino acids, high-fructose sugar, 6-aminopenicillanic acid, malic acid, etc.6 Furthermore, the method of immobilized enzymes has been advanced. By using microbial cells that still contain enzymes (immobilized microorganisms), extraction and purification operations can be omitted, and stability during immobilization or manipulation is good.
It has advantages such as being advantageous in using a multi-step enzyme system and being able to supply coenzymes, ATP, etc. Furthermore, a method of immobilizing living microorganisms can be used to produce secondary metabolites, and it is also possible to improve the yield by using immobilized growing microorganisms.

の余地が大きい。In aerobic fermentation production technology, the rate of diffusion of nutrients and oxygen influences the rate of production of the desired product. In general, the utilization efficiency of nutrient sources is low, and the viscosity of the culture solution increases due to bacterial cell proliferation and product production, inhibiting biosynthetic reactions and reducing the production rate of the desired product. In the case of filamentous fungi, shortages of nutrients and oxygen are particularly likely to occur due to the formation of borders with a three-dimensional network structure and thickening of the culture solution. Also,
There is a lot of room for improvement, as it takes time and effort to separate the products from the culture solution.

明を完成するに至った。The present inventors have conducted extensive research into immobilization methods that are inexpensive, durable, simplify processes and operations, improve productivity, and are highly stable in fermentation production and substance production using immobilized biocatalysts (enzymes and microorganisms). As a result, by using a polymer membrane to support a biocatalyst, the surface area is large, and there is no dense growth of bacterial cells or the formation of boundaries, so nutrients and oxygen are supplied sufficiently, and it is durable. It can be used repeatedly for a long period of time, and it is highly productive as it is possible to use not only proliferating cells but also resting cells.Furthermore, since the cells are inside the membrane, sterilization of the culture solution is unnecessary and complicated. It was discovered that no extensive gel preparation operation was required, and based on this finding, the present invention was completed.

Approximately 100 bacterial cells of rum LehLIlanNolO-1
mg was placed in a bag, and the entrance of the bag was sealed by heating using a sealer. The 10 bags thus made were placed in an IQ wide-capacity Ropoly bottle containing 300 ml of unsterilized medium with the following composition, the mouth was covered with aluminum foil, and the reciprocating excitation incubator (amplitude 70 mm, 120 reciprocating cycles/min) was used while ventilating. ) and cultured at 30°C for 6 days. As fermentation progressed, the culture solution foamed significantly. After culturing, when the bag was cut open, bacterial cells with a thickness of about 0.5++ m were adhered to both sides of the nonwoven fabric in a film shape (weighing 1°), and no leakage of cultured bacterial cells to the outside of the membrane was observed. The amount of glucose in the culture solution was 2.4% according to a glucose meter. The viscosity did not change from the viscosity of the culture solution at the time of preparation, which was 10 cp. Furthermore, add ethanol to the fermentation liquid and IN sodium hydroxide 1
After neutralizing by adding 00 mQ of IN hydrochloric acid, the ring-opened form (1,3

ium spiculisporum Lehman
Three sealed bags containing 100 mg of No1O-1 were prepared. These three bags were placed in an IQ wide mouth bottle containing 300 wM of culture solution, the mouth was covered with aluminum foil, and cultured at 30° C. in the same manner as in Example 1. The implementation results were Experiment No. 2 in Table 1, in which the production efficiency of 2-sporic acid decreased.

実施例1と同じジュラガード3501 (0,4X0゜

すると培養開始時とほぼ同量の菌体量であった。Example 3 A 50 x 40 mm bag made of the same Duragard 3501 (0.4 x 0° 04 μff1) as in Example 1 was made, and 100 mg of bacterial cells was sealed in the bag without inserting a nonwoven fabric. When opened after 6 days, the amount of bacterial cells was almost the same as at the start of culture.
それ故、菌体を担持し増殖させるために不織布を袋の中
に入れることが必要であることがわかった。Therefore, it has been found that it is necessary to insert a nonwoven fabric into the bag in order to support and propagate the bacterial cells.

確認した。Example 5 Ten polymer membrane bags in which the bacterial cells obtained in Example 1 were grown and immobilized on a non-woven fabric were taken out and placed on a glass funnel to allow the culture solution to drip naturally and removed, followed by repeated washing with water. Ta. Utilizing the enzyme system of the mycelia immobilized in these bags, biosynthesis (bioconversion) of spicrysporic acid was carried out using an IQ wide-capacity bottle filled with 300 mQ of the medium shown in the table below containing the substrate.
