PROBLEM TO BE SOLVED: To obtain the subject biopolymer useful as a bioremediation effect- promoting agent and a fluidity-controlling agent, etc., from cultured products by culturing a specific microorganism in a culture medium containing a hydrocarbon. SOLUTION: A microorganism belonging to the genus Pseudomonas, capable of assimilating hydrocarbons and producing a water-soluble polysaccharide biopolymer, e.g. Pseudomonas sp. SLI (FERM P-16011) is cultured in a culture medium containing a hydrocarbon and a water-soluble polysaccharide biopolymer is harvested from cultured products. The microorganism is useful for petroleum purification process, bioreactor, waste water treatment, biopolymer-producing process, etc. |
