A novel strain exhibiting high laccase activity was screened and purified from forest soil of Liangshui National Nature Reserve in Heilongjiang with Cu2+ as the enrichment culture reagent. The strain was identified as Bacillus subtilis WD23 by the morphological, physiological, biochemical characteristics and the comparative analysis of 16S rDNA sequence. The strain showed optimum growth at 30°C and...
The synergistic effect of microbial consortium S3 (including S3-1, S3-2, S3-3 and S3-4), which has the ability of degrading Polycyclic Aromatic Hydrocarbons was studied by solid phenanthrene as the sole source of carbon and energy. The research showed that only S3-1 had the characteristics of phenanthrene-degrading and other three strains could use the metabolites of S3-1 in different degree. It was...
A microbial community could decomposed 55.1% of rice straw in weight within 5 days, among them cellulose content decreased by 63.4% and hemicellulose content decreased by 43.9%. And the content of water soluble carbohydrates (WSC) in the fermentation broth increased progressively during the initially days, and decreased thereafter, suggesting an accumulation of WSC in the early phase of the degradation...
