Abstract: Bacteria were isolated from various samples as agricultural soil, red soil and sewage water. The isolates were screened for Polyhydroxy butyrate production by sudan black dye staining method. The isolates were further confirmed by staining. The resistance and susceptibility pattern of the isolates to different antibiotics and heavy metals was analyzed. The zones obtained revealed that the isolates were susceptible to a few antibiotics, but were found to be resistant to Penicillin G, Ampicillin, Vancomycin and Cefixime, whereas the isolates were highly resistant to zinc sulphate and copper sulphate and moderately resistant to silver nitrate, thus revealing the co-existance of resistance to antibiotics and heavy metals.
