PROCESS FOR PREPARING DYE-FREE POLYHYDROXYALKANOATES

摘要

FIELD: microbiology. SUBSTANCE: polyhydroxyalkanoates are synthetized in cells as accumulators when cultivating bacterial biomasses. Dried bacterial mass is first maintained for 10-120 minutes at temperature ranging from 80 C to lower limit of melting of polyhydroxyalkanoates and extracted with acetic, acid 1-10 vol% of aliphatic derivative of carboxylic acid being added to the agent to be extracted. EFFECT: more efficient preparation process.
