In the method of allowing the present microorganism to act on the 3-picoline derivative, the present microorganism may be cultured in a medium containing the 3-picoline derivative, or the cells of the microorganism or a treated product of the cells may be used in an aqueous solution. -It may be contacted with a picoline derivative.
As a method for converting a 3-picoline derivative into a nicotinic acid derivative by culturing the present microorganism, the microorganism of the present invention may be cultivated in a medium containing the 3-picoline derivative from the beginning of the culturing, or 3 -The picoline derivative may be added to the medium. The medium used for culturing the present microorganism is a usual medium containing a carbon source, a nitrogen source, inorganic ions and, if necessary, an organic nutrient source which the present microorganism can assimilate. As the carbon source, carbohydrates such as glucose, alcohols such as glycerol, organic acids, etc. are appropriately used. As the nitrogen source, ammonium salts, nitrates, etc. are used. As the inorganic ion, magnesium ion, iron ion, copper ion, phosphate ion, and the like are appropriately used as necessary. As the organic nutrient source, vitamins, amino acids and the like, yeast extract, polypeptone, meat extract and the like containing these are appropriately used. The desired results can be obtained if the culture is carried out under aerobic conditions while controlling the pH within the range of 6 to 10 and the temperature within the range of 20 to 42 ° C. Thus, if the culture is carried out for 1 to 20 days,
The 3-picoline derivative is efficiently converted into a nicotinic acid derivative.

On the other hand, when the cells of the present microorganism or the treated product of the microorganisms are brought into contact with the 3-picoline derivative in an aqueous solution to act, the 3-picoline derivative and the cells or the treated product of the cells are suspended or 15-45 ° C in the dissolved aqueous solution,
Preferably 25-35 ° C, pH 5-10, preferably 6
It may be agitated or allowed to stand for a while while being maintained at -9. The concentration of the 3-picoline derivative is 0.01 to 5%, preferably 0.1.
It is 5% or less, and the 3-picoline derivative may be supplementarily added during the reaction. As the cells, a culture solution containing the cells may be used as it is. In addition, this may be used once after being separated from the culture solution and washed or not washed. As the method for obtaining such cells, the above-mentioned medium and culture method can be employed as they are, but it is desirable to add a small amount of 3-picoline to the medium. Further, in this case, the culture may be completed in about 15 to 72 hours because the microorganisms may sufficiently grow in this case. If necessary, carbohydrates such as glucose, alcohols such as glycerol, organic acids, or metal ions may be added to the aqueous solution to improve the conversion efficiency. Thus, even after 1 to 20 days, the 3-picoline derivative in the aqueous solution is efficiently converted into the nicotinic acid derivative.
