Cell dry mass (CDM) and PHB production from Bacillus sp. CYR1. Bacteria were
incubated at 100 mg/l concentration of different aromatic compounds and 0.02%
Tween-80 in MSM media at 30 C. For CDM measurement cells were harvested by
centrifugation, washed twice with phosphate-buffer and dried for 24 h at 80 C until a
stable weight was reached. PHB was extracted from the CDM using sodium
hypochlorite–chloroform extraction method.
