PURPOSE:To produce desired fermentation product, by subjecting the residual mother liquid obtained by separating latex from milk of natural rubber to concentration treatment, etc., to give fermentation medium and inoculating and propagating a fungus or bacterium into the culture medium. CONSTITUTION:The mother liquor (natural rubber serum) of residue obtained by separating a latex from natural rubber milk is concentrated or powdered by spray-drying method and the resultant concentrate or powder is directly used as a fermentation culture medium or added to a fermentation culture medium to prepare a fermentation culture medium. Then a bacterium (containing actinomyces) or fungus (yeast or filamentous fungus) is inoculated into the fermentation culture medium and propagated to produce the microbial cell and/or accumulate a specific fermentation product. The natural rubber serum discharged from plants, etc., in south east asia can be used as a raw material for the culture medium and effective utilization of the natural rubber serum can be contrived according to the above-mentioned method. |
