Two native Bacillus isolates produced PHB using agricultural wastes like wheat straw, rice straw, sugarcane bassage, corn cobs and saw dust. Bacillus sp. 87I produced 50.9% (1.5 g/l PHB), when sugars from sugarcane bassage were used in E2 media. The second Bacillus sp. 112A produced 47.5 % (1.1 g/l) of PHB, when filtrate from sugarcane bassage fermentation was used as carbon substrate. The native Bacillus spp. 112A and 87I have desirable properties of tolerance to high conditions of pH and temperatures.
