【中文摘要】 Changes in the bacterial communities inhabiting Agaricus bisporus compost during Phase Ⅱ treatment were monitored using amplified rDNA restriction analysis(ARDRA).Sequence analysis data indicated that the bacterial communities associated with the compost samples were far richer in composition when determined by ARDRA compared with traditional methods based on bacterial isolation.Furthermore,the composition of the communities,especially in terms of the dominant bacteria during each of the four tr...更多eatment stages(beginning of Phase Ⅱ,after pasteurization,5 days aeration,end of Phase Ⅱ,respectively),were very different.Restriction endonuclease digestion of mainly bacterial clones from four 16S rDNA libraries,C1,C3,C6 and C7,previously constructed on the basis of 16S rDNA fragments amplified from the four different stages of the Phase Ⅱ composting process,revealed the presence of unique microbial types.Thermophilic bacteria belonging to the Bacilli,and previously unreported strains of Trichococcus,Planococcus,Caryophanon,and subclass γ-Proteobacteria,were identified among the clones from the compost sampled during the aeration period(C6).Bacteria belonging to Thermus thermophilus and subclass α-Proteobacteria were detected in C1 and C7 composts sampled at the beginning and the end of Phase Ⅱ,respectively.Clones of some uncultured bacteria were also scored.  還原
