A method of extracting liposoluble components contained in microbial cells, including the steps of drying microbial cells containing liposoluble components, descructing and molding the resultant dry microbial cells by use of an extruder, particularly a twin screw extruder, and extracting the contained liposoluble component by use of an organic solvent. According to the present method, liposoluble components contained in cells can be extracted and recovered with enhanced efficiency, within short time, and with safety.

Method for extracting fat-soluble components from microbial cells

A suspension of a sparingly water-soluble acidic drug, especially, a nonsteroidal anti-inflammatory analgesic agent, which is stable for a prolonged period of time and is highly dissolvable, and a process for simply and easily producing the suspension. This suspension has a pH value of 2 to 5 and comprises a sparingly water-soluble acidic drug whose average particle size ranges from 1 to 15 &mgr;m, a polyglycerol fatty acid ester, a water-soluble polyhydric alcohol and water, optionally, together with an inorganic powder having an average particle size of 1 to 15 &mgr;m. This process is characterized by carrying out pulverization and dispersion of a sparingly water-soluble acid drug, a polyglycerol fatty acid ester, a water-soluble polyhydric alcohol and water by means of a pulverizer comprising a main shaft adapted to rotate in a casing and a plurality of layshafts adapted to revolve in relationship interlocked with the rotation of the main shaft, each of the layshafts being fitted with a multiplicity of annular griding media.

Stable liposome aqueous suspension

Dihomo-.gamma.-linolenic acid is produced by cultivating a microorganism having an ability to produce dihomo-.gamma.-linolenic acid on a culture medium containing a compound having an ability to inhibit an unsaturation reaction at a .DELTA.5-position of fatty acid.

Process for production of dihomo-.gamma.-linolenic acid and inhibitor

Method for the production of lipds containing bis-homo-.gamma.-linolenic acid and/or arachidonic acid using microorganisms belonging to a genus Conidiobolus and capable of producing the lipids. The microorganisms are cultured on a medium containing an unsaturated fatty acid as a carbon source. The unsaturated fatty acid may be supplied as an additional carbon source in the course of culture. Preferably, the unsaturated fatty acid has 18 carbon atoms and 1 to 3 double bonds.
