TLDR
Studies of tropical wetlands, including rice paddies and swamps, and the study of a variety of ruminants in the tropics are particularly interesting and appropriate at this time, with respect to methane produced in these ecosystems.Abstract:
Methane produced microbiologically is currently used as an energy source, especially by cities and industries, albeit at a level far below its potential; the incentive is currently to save money on disposal costs for waste problems. Anaerobic digestion can be helpful in degrading several halogenated hydrocarbon wastes, and methanogens are partly responsible. Ethane instead of methane may be a future product of interest. Some pure cultures of methanogens may be suitable for production of B-12, or perhaps the speciality biochemical F420, a 5-deazaflavin of interest to both methanogen and streptomyces researchers. Methanogens can cause a variety of problems, including biocorrosion, increased atmospheric methane, and ruminant nutrition loss. Studies of tropical wetlands, including rice paddies and swamps, and the study of a variety of ruminants in the tropics are particularly interesting and appropriate at this time, with respect to methane produced in these ecosystems. In some cases, it may be possible to control methane production by the use of inhibitors or ecological control mechanisms.read more

TL;DR: The extremely parallel SOLiD™ short-read DNA sequencing platform is demonstrated to be capable of providing sufficient useful information to decipher the systematic and functional contexts within a biogas-producing community, and this systematic methodology allows the design of the optimal microbial community structure for anyBiogas plant.

TL;DR: Results suggest that species related to those of the genus Methanoculleus play a dominant role in methanogenesis in the analysed fermentation sample, and assignment of numerous contig sequences toClostridial genomes including gene regions for cellulolytic functions indicates that clostridia are important for hydrolysis of cellulosic plant biomass in the biogas fermenter under study.

Top-Down Proteomics Reveals Novel Protein Forms Expressed in Methanosarcina acetivorans
TL;DR: Using both automated nanospray and online liquid chromatography mass spectrometry LC-MS strategies, 99 proteins have been newly identified by top-down tandem mass spectroscopy in Methanosarcina acetivorans, the methanogen with the largest known genome for an Archaeon.

Comparison between wet and semi-dry anaerobic biogas diester under thermophilic and mesophilic conditions: Methane productivity and analysis of microbiota
TL;DR: In this article, a high-speed semi-dry methane fermentation system for cow manure was established, by comparing productivity in wet and semi dry conditions, and mesophilic and thermophilic conditions (38 and 55°C, respectively).
