Diversity of culturable moderately halophilic bacteria producing extracellular ...
Wei, Shiping; Liu, Beibei; Cui, Hongpeng; Fan, Rui; Guo, Ce; Sun, MingxueA total of 114 moderately halophilic bacteria were isolated from marine sediment environments. The isolates are belonged to 23 species based on the 16S rRNA sequence analysis. 63, 52, 47, 57, 74, 15 and 4 isolates are able to produce protease, amylase, lipase, pectinase, pulluanase, xylanase, cellulase, respectively. Combined hydrolytic enzyme activity analysis show that 15 strains present 1 hydrolytic activity...
Vertical distribution of archaeal communities in cold seep sediments from the j...
Cui, Hongpeng; Su, Xin; Chen, Fang; Wei, Shiping; Chen, Sihai; Wang, JinlianJiulong methane reef, a large cold seep area on the continental slope of the South China Sea (SCS), was characterized by chemosynthetic fauna, bacterial mats, methane-derived carbonate structures, and a shallow depth of sulfate-methane transition zone (SMTZ) in gravity cores. To characterize the microbial diversity and variation in correlation to methane venting in the cold seep area, the archaeal community in ...
Microbial conversion of waste cooking oil into riboflavin by Ashbya gossypii
Wei, Shiping; Zhao, Fang; Jiang, Zhenglong; Zhou, DongshengThe conversion of waste cooking oil into riboflavin by Ashbya gossypii was investigated in this paper. The effect of initial pH and the original volume of added waste cooking oil in the medium were evaluated to optimize the fermentation efficiency. The results show that when the initial pH was adjusted to 6.5 and 40 g/L waste cooking oil was added in the medium, no residual waste cooking oil was observed and th...
