Study Data from Zhejiang University Update Knowledge of Applied microbiology and biotechnology

June 4, 2014



By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Biotechnology are discussed in a new report. According to news reporting originating from Hangzhou, People's Republic of China, by NewsRx correspondents, research stated, "Despite advancing knowledge about the functional role of actinomycetes in degrading lignocellulosic materials, definitive knowledge concerning the diversity and dynamics of the actinomycetal community in composting is still lacking. In this study, real-time polymerase chain reaction (PCR) coupled with denaturing gradient gel electrophoresis (DGGE) and clone library construction were applied to investigate actinomycetal diversity and dynamics in a pilot-scale composting."

Our news editors obtained a quote from the research from Zhejiang University, "Quantitative real-time PCR data revealed that actinomycetes accounted for 18-86 % of bacteria and that the fraction peaked during the maturing phase, indicating that Actinobacteria were critical to the compost ecosystem. Qualitatively, actinomycetal communities displayed distinct temporal variations during composting. Fourteen distinct genera of actinomycetes and an unknown group were observed in manure composts. Redundancy analysis indicated that temperature exerted an influence over the actinomycetal communities. Specifically, pathogenic Corynebacterium species dominated in the initial phase, whereas the genera Saccharomonospora and Thermobifida were abundant in the thermophilic phase. In maturing composts, mesophilic Micrococcineae members were most prevalent. The dominant thermophiles along with Micrococcineae may jointly facilitate the degradation of lignocellulosic materials during composting."

According to the news editors, the research concluded: "Together, our research revealed a more detailed ecological and potential functional role for actinomycetes in the compost ecology."
