ABSTRACT:
A microorganism belonging to the genus Flavobacterium posessing the capacity to decompose hydrocarbons, tolerance to sulfurous acids, tolerance to salinity, tolerance to organic solvents, and tolerance to pressure. The microorganism is of a strain of the genus Flavobacterium DS-711 (FERM BP-4010). A hydrocarbon emulsifier or solubilizer having as an active component thereof a water soluble and acetone insoluble fraction obtained by culturing DS-711 strain. In addition the emulsifier or solubilizer obtained by culturing the strain DS-711 contains 18.4% protein, 18.8% carbohydrates and 28.6% lipids. A separation method for an organic-solvent tolerant microorganism, wherein a sample is mixed with water and an organic solvent, shaking culturing is conducted, a cultured mixture is allowed to stand, separation into an aqueous phase and an organic solvent phase is conducted, an appropriate amount of said organic solvent phase is added to a culture medium and cultured, and microorganisms which grow therein are isolated.
