Enhanced biosynthesis of polyhydroxyalkanoates in a mutant strain of Rhizobium meliloti.

Biotechnology letters - 1 Jan 2003

Lakshman Kshama, Shamala Tumkur Ramachandriah

Abstract excerpt

Strains of Rhizobium spp. isolated from leguminous plants and standard strains accumulated 27% to 57% polyhydroxyalkanoate (PHA) of their cell biomass. Among these cultures, one strain of Rhizobium meliloti synthesized 10-30% more PHA than others and contained 3% hydroxyvalerate (HV) when grown on sucrose as carbon substrate. The occurrence of hydroxybutyrate (HB) and HV was confirmed by GC and 1H NMR analysis....
