| Research Abstract |
Basic research for the development of the efficient system for microbial conversion of unused plant biomass to beneficial materials at low temperatures was carried out. In the rice field soil, cold-adapted anaerobes were enumerated with MPN-cultures at 5oC or 10oC at the value comparable to that of mesophilic anaerobes enumerated at 30℃. The 16S rDNA phylogeny indicated that cold-adapted anaerobes growing in the cold MPN-cultures were most closely related to bacteria such as psychrophiles isolated from an Antarctic lake. All of 52 isolates from cold MPN-cultures grew well at 5oC, and most of them grew even at 0oC. The anaerobic microbial community in the rice field soil harbored a complete set of anaerobic microorganisms necessary for the degradation of plant biomass to methane at low temperatures, e.g.,10℃
