Poly-β-hyroxybutyrate production by root nodule ısolates of wild vicia faba

Abstract

Poly-β-hyroxybutyrate is a common bacterial polymer. It has been ecofriendly and best alternative biopolymer against environmental pollution. In this study, the poly-β-hyroxybutyrate (PHB) contents of Rhizobium isolates from isolated wild Vicia faba were studied in the media used by a spectrophotometric technique. The dry cell weights and PHB production of isolates were different. The production of PHB by 18 isolates ranged between 0.006-0.720 g/l with a productivity of 0.273-19.3 (%). B7 isolate produced more PHB than the other isolates.
