Data on Microbiology and Biotechnology Reported by Researchers at Nanjing Agricultural University (Variations of culturable thermophilic microbe numbers and bacterial communities during the thermophilic phase of composting)

By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Biotechnology have been presented. According to news reporting originating from Jiangsu, People's Republic of China, by NewsRx correspondents, research stated, "Composting is a process of stabilizing organic wastes through the degradation of biodegradable components by microbial communities under controlled conditions. In the present study, genera and species diversities, amylohydrolysis, protein and cellulose degradation abilities of culturable bacteria in the thermophilic phase of composting of cattle manure with plant ash and rice bran were investigated."

Our news editors obtained a quote from the research from Nanjing Agricultural University, "The number of culturable thermophilic bacteria and actinomyces decreased with the increasing temperature. At the initiation and end of the thermophilic phase, genera and specie diversities and number of bacteria possessing degradation abilities were higher than during the middle phase. During the thermophilic composting phase, Bacillus, Geobacillus and Ureibacillus were the dominant genera, and Geobacillus thermodenitrificans was the dominant species. In later thermophilic phases, Geobacillus toebii and Ureibacillus terrenus were dominant. Bacillus, at the initiation, and Ureibacillus and Geobacillus, at the later phase, contributed the multiple degradation abilities."

According to the news editors, the research concluded: "These data will facilitate the control of composting in the future."
