Degradation of tetrachloromethane was examined in the three strictly anaerobic bacteria, Acetobacterium woodii. Desulfobacterium autotrophicum and Methanobacterium thermoauwtrophicum. When incubated under anaerobic conditions in reduced buffer, suspensions of each organism degraded CCI4 by both reductive and substitutive mechanisms. The products formed included less-highly chlorinated methanes ...

BACKGROUND Numerous cancers have been linked to microorganisms. Given that colorectal cancer is a leading cause of cancer deaths and the colon is continuously exposed to a high diversity of microbes, the relationship between gut mucosal microbiome and colorectal cancer needs to be explored. Metagenomic studies have shown an association between Fusobacterium species and colorectal carcinoma. Her...

background anaerobic-inducible promoters are alternatives of chemical-inducible promoters for expression of recombinant proteins especially in conditions where chemical induction is not possible or anaerobic conditions are preferable. the nirb promoter is the promoter of the first gene of nir operon in escherichia coli, which encodes nadh-dependent nitrite reductase. this promoter is naturally ...

Anaerobic continuous stirring tank reactor (CSTR) was employed for biohydrogen production by anaerobic co-digestion from the mixture of herbal wastewater (HW) and monosodium glutamate (MGW). A series blend volumetric proportions (MGW/HW), organic loading rates (OLR) were used as control strategy evaluated optimal production. The highest 7260±7.7 mL L -1 d attained at proportion 15%, OLR 41 g CO...

Co-digestion of dairy manure with off-farmwaste has become a common practice on US farms, however, little data at a commercial-scale is present within the literature. In response, a mesophilic, mixed plug-flow reactor co-digesting 16.36% v/v food processing substrates with dairy manure, was monitored for its performance and substrate effects. Co-digestion, as compared to substrate or manure-onl...

The biochemical methane potential (BMP) of raw poultry litter waste was assessed in batch assays. Biological co-treatment with Clostridium cellulolyticum, Caldicellulosiruptor saccharolyticum and Clostridium thermocellum as bioaugmentation strains, and thermochemical pre-treatments with lime and sodium hydroxide performed at different temperatures and pressures were applied as strategies to imp...
