专利说明:

This invention relates to technical microbiology and relates to a process for the preparation of 2-keto-O-glucaric acid, which can be used as an additive to the feed for the preparation of detergents, plasticizers for cement, and as a reagent in studying the metabolism of saccharides.
A method of producing 2-keto-O-glucaric acid by microbiological oxidation of D-glucaric acid by the action of the microorganism Pseudomonas aeruglnosa is known. D-glucaric acid is obtained from glucose by chemical oxidation.
The disadvantage of this method is the high cost of the target product.
The purpose of the invention is to reduce the cost of the product.
As the precursor of 2-keto-O-glucaric acid, monosaccharides or their derivatives of the general formula are used.

Strains K591c, 12-5,12-15,12-4, and 22-3 do not belong to the known genera, but represent a new bacterial species of the new
genus, named Pseudogluconobacter saccharoketogenes.
These bacterial strains are sometimes referred to as oxidizing bacteria. Their nutritional needs for growth are as follows.
Strains K519c, 12-5, 12-15 have unusual nutritional requirements, i.e. for growth they need CoA. In these three strains, coenzyme A cannot be replaced by pantothetic acid. Strains 12-4 and 22-3 can grow in the presence of CoA and / or pantothenic acid.
Bacterial strains also include mutants obtained by irradiating these strains with ultraviolet and x-rays or treating them with chemical mutagens, for example, M-methyl-M-nitro-M-nitrosoguanidine (nitrosoan-guanidine), methyl methanesulfonate or nitrogen-containing mustard.
An example of a mutant is the strain TH14-86, which is obtained from strain K591 by treatment with nitrosoguanidine. This strain has taxonomic characteristics similar to the parent strain, except that it exhibits an increased ability to form 2-keto-0-glucaric acid from saccharides.
The strains K591s, 12-5, 12-15, 12-4, 22-3 and TN 14-86 are deposited at the Fermentation Institute, Osaka (IFO), and also at the Fermentation Research Institute (FERM) of the Agency of Industrial Science and Technology Ministries of International Trade and Industry. On the basis of the Budapest Treaty, these microorganisms are stored in FRI,
Depository numbers of microorganisms are presented in table.1.
Compounds that are used as precursors in the invention include D-glucose, D-fructose, D-mannose, D-sorbitol, D-mannitol, D-gluconic acid, 2-keto-O-gluconic acid, D-glucosone and O-mannonic acid (these compounds are further saccharides).
The saccharides can be introduced into the medium either at the beginning of the culture in several portions or continuously during the whole culture process. The concentration of saccharides in the reaction liquid5 should be 5–20 May. % / volume
In the reaction liquid, the pH is set in the range of 5.5 to 7.5. The temperature and reaction time of the oxidation are maintained in the range of about 23-35 ° C and about 50-100 hours. The culture medium can be either liquid or solid. In the environment include sources of carbon, nitrogen, mineral and organic acid salts and nutrients in the number of traces. Saccharides can be used as carbon sources without processing. As an additional carbon sources, glycerin, sucrose, lactose, maltose, molasses can be used.
Ammonium salts (sulfate, nitrate, chloride, phosphate), corn extract (hereafter CSL), peptone, meat extract, yeast extract, dry yeast, soy flour, cotton seed flour and urea are sources of nitrogen in the medium. Mineral salts include the salts of potassium, sodium, calcium, magnesium, iron, manganese, cobalt, zinc, copper.
Nutrients that are used in trace amounts include vitamins necessary for the growth of these bacteria, for example CoA, pentothenic acid, biotin, thiamine and riboflavin, as well as compounds with a stimulating effect on the growth of bacteria and the production of 2-keto-O-glucaroxy acids, for example, flavin mononucleotide (FMN), flavin adenine dinucleotide (FAD), other vitamins, L-cysteine, L-glutamic acid and sodium thiosulfate in the form of either chemical compounds or natural substances that contain them.
The cultivation of bacteria is carried out by the methods of static cultivation, shaking in flasks, and submerged cultivation. Cultivation conditions depend on the bacterial strain, medium composition and other factors. Sterilized bacterial cultures can be used as medium components.

removed previously from the reaction liquid by filtration or centrifugation. If necessary, activated carbon discoloration is carried out. The solution is then concentrated until precipitation of crystals. The resulting crystals are collected and recrystallized.
