Utilization of the novel, environmental isolates Pseudomonas sp. IPB-B26 and N-128 for the efficient high yield production of mcl/lcl-PHAs

摘要

The present application is directed at microorganisms of the genus Pseudomonas as deposited under DSM26199 ( Pseudomonas sp. IPB-B26) and DSM26200 (Pseudomonas sp. N-128) with the Leibnitz Institute DSMZ. The present application is further directed at a process for the production of medium- and long-chain-length PHAs, comprising cultivating said microorganisms in a culture medium comprising a carbon source and isolating the PHA from the microorganisms. It has been observed that these microorganisms allow for efficient PHA production in high yields. In addition, the inventive microorganisms possess the valuable capability to incorporate unsaturated fatty acids into the resulting PHAs. The inventive microorganisms thus enable a later modification of the PHAs as well as crosslinking, thus opening new fields of applications for these materials.
