摘要

The process of obtaining PHA from waste citric, PHA obtained from waste citric acid, polymer containing composition containing PHA, PHA solid artifact artifact containing polymeric composition comprising solid, PHA, use of citric acid residue for obtaining PHA.The present invention relates to a process for the production of biodegradable polymers from citric acid waste from the processing of orange juice. The obtained polyester polymers are classified as polihidroxialcanoatos including, among these, the poly (3-hydroxybutyrate) and poly (3-hydroxybutyrate - co - 3 - hidroxivalerato).The pol imero biodegradable is obtained from the cultivation of the type batch or batch process with or without recirculation cells using as carbon source in the liquor of pressing and / or molasses citric acid pre treated.The pou00edihidroxialcanoatos, described here, may be used as replacements for synthetic polymers in various areas including food, pharmaceutical, medical, agricultural, and other.
