, or microorganisms derived from, are grown in a culture medium including propionic acid. The propionic acid increases the production of one or more of dry cell weight, total lipid and docosahexaenoic acid.

is cultured in a suitable growth medium with acetic acid/acetate as the main carbon source. The acetate is provided, and replenished, by adding acetic acid to the growth medium in response to an increase in pH resulting from the utilisation of acetic acid/acetate by. Theproduces relatively high levels of docosahexaenoic acid (DHA). A stationary phase is not essential for satisfactory DHA production.

Method of producing an oil including docosahexaenoic acid

A microbiological process, capable of producing polymers comprising monomer repeat units of the structure

Microbiological production of polyesters having C.sub.8 and/or C.sub.10

A process for the synthesis of copolymers comprising 3-hydroxybutyrate (HB) and 3-hydroxyvalerate (HV) units by the cultivation of certain strains of Corynebacterium, and Rhodococcus, some of which are novel on a substrate containing e.g. glucose. The process can also be used to produce the previously unknown homopolymer of HV by using a substrate of valeric acid.
