| Abstract;Isolation of bacteria which could decompose styrene and polystyrene as carbon source was achieved to actualize the biological zero emission treatment of expanded polystyrene. Isolated microorganisms by 16S ribosomal DNA analysis were Pseudomonas sp. and Bacillus sp. for styrene decomposition, and Xanthomonas sp. and Sphingobacterium sp. for polystyrene decomposition. Especially, Bacillus sp. STR-Y-O strain decomposed both styrene and polystyren. Styrene and polystyrene were reduced 40% (9g) and 56% (34g) of initial concentrations (quantity), respectively, in 8 days by strain STR-Y-O. The result is the first report for polystyrene biodegradation. It became possible that limonene melted expanded polystyrene, and styrene and polystyrene as melting matter were decomposed by the isolated microorganisms. In a series of experiments, the possibility that the zero emission process of expanded polystyrene was shown by those microorganisms. (author abst.) |
