Polyhydroxyalkanoate production in Rhodobacter capsulatus: genes, mutants, expression and physiology
Article Abstract:
The phaA, phaB and phaC genes of Rhodobacter capsulatus that are responsible for polyhydroxyalkanoate (PHA) biosynthesis have been isolated and inactivated. The phaC-lacZ and phaAB-lacZ reporter genes were found to be expressed even in the absence of the nitrogen or carbon source. Mutant genes of R. capsulatus could still synthesize the PHAs even if these genes have been eliminated from the transcriptional nitrogen regulatory pathway.

Cold-active chemoorganotrophic bacteria from permanently ice-covered Lake Hoare, McMurdo dry valleys, Antarctica
Article Abstract:
Eight strains of chemoorganotrophic bacteria which were isolated from the water column of Lake Hoare, McMurdo Dry Valleys, Antarctica by using cold enrichment temperatures revealed that at least two major phyla of bacteria inhabit Lake Hoare.
