Abstract: EP 536046 A2<br />

A novel microorganism belonging to the genus<br />

Flavobacterium posessing the capacity to decompose<br />

hydrocarbons, tolerance to sulfurous acids, tolerance<br />

to salinity, tolerance to organic solvents, and tolerance<br />

to pressure. The novel microorganism is of a strain of<br />

the genus Flavobacterium DS- (FERM P-).<br />

A hydrocarbon emulsifier and solubilizer having as an<br />

active component thereof a water soluble and acetone<br />

insoluble fraction obtained by culturing DS- strain.<br />

A separation method for an organic-solvent tolerant<br />

microorganism, wherein a sample is mixed with water<br />

and an organic solvent, shaking culturing is conducted,<br />

a cultured mixture is allowed to stand, separation<br />

into an aqueous phase and an organic solvent phase is<br />

conducted, an appropriate amount of said organic solvent<br />

phase is added a culture medium and cultured,<br />

and microorganisms which grow therein are isolated.<br />

Claims: EP 536046 A3<br />

. A novel microorganism belonging to the genus<br />

Flavobacterium possessing an ability to decompose<br />

hydrocarbons, tolerance to sulfurous acids,<br />

tolerance to salinity, tolerance to organic solvents,<br />

and tolerance to pressure.<br />

. The novel microorganism of claim , wherein said<br />

microorganism is DS- strain of the genus<br />

Flavobacterium.<br />

. A hydrocarbon emulsifier and solubilizer having as<br />

an active component thereof a water soluble and acetone<br />

insoluble fraction obtained by culturing DS-<br />

strain of the genus Flavobacterium (FERM P-)<br />

in a culture medium containing hydrocarbons.<br />

. A separation method for an organic-solvent tolerant<br />

microorganism, wherein a sample is mixed<br />

with water and an organic solvent, shaking culturing<br />

is conducted, a cultured mixture is allowed to<br />

stand, separation into an aqueous phase and an<br />

organic solvent phase is conducted, an appropriate<br />

amount of said organic solvent phase is added to a<br />

culture medium and cultured, and microorganisms<br />

which grow therein are isolated.<br />

. The method of claim , wherein said shaking culturing<br />

is conducted for a period of - days at a<br />

temperature of - (degree) C.<br />
