| Abstract: | Pseudoalteromonas sp. NRRL B-30083 was isolated as the predominant PHBV-degrading organism from a tropical marine environment. In complex medium, the isolate grew well at temperatures between 23°C and 33°C, with an optimal doubling time of about 30 min. NaCl was required at concentrations between 0.2 N and 0.8 N. Optimal pH levels for growth were between pH 6.5 and pH 8.5. Liquid cultures grew modestly on PHBV as a sole carbon source under optimal conditions, although PHBV depolymerase activity was not detected. |
