CleanMat, EarlyView.Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

Isolation and characterization of a thermophilic, obligately anaerobic and heterotrophic marine Chloroflexi bacterium from a Chloroflexi dominated microbial community associated with a Japanese shallow hydrothermal system, and proposal for Thermomarinilinea lacunofontalis gen. nov., sp. nov. [PDF]
, 2013 A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent of the Taketomi submarine hot spring field located on the

Methanogens: pushing the boundaries of biology
Emerging Topics in Life Sciences, 2018 Methanogens are anaerobic archaea that grow by producing methane gas. These microbes and their exotic metabolism have inspired decades of microbial physiology research that continues to push the boundary of what we know about how microbes conserve energy

Energy Science &Engineering, EarlyView.This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Levels of Water-Soluble Vitamins in Methanogenic and Non-Methanogenic Bacteria [PDF]
Applied and Environmental Microbiology, 1983 The levels of seven water-soluble vitamins in Methanobacterium thermoautotrophicum, Methanococcus voltae, Escherichia coli, Bacillus subtilis, Pseudomonas fluorescens , and Bacteroides thetaiotaomicron were compared by using a vitamin-requiring Leuconostoc strain. Both

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Optimizing Genetic Manipulation of Methanogens through Faster Cloning Techniques [PDF]
, 2018 Methanogenesis is the biological production of methane. Only anaerobic archaea known as methanogens are capable of such a metabolic feat. They have strict living conditions and substrate sources which determine their rate of metabolism.

Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion [PDF]
, 2012 This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

The diversity of hydrogen-producing bacteria and methanogens within an in situ coal seam
Biotechnology for Biofuels, 2018 BackgroundBiogenic and biogenic-thermogenic coalbed methane (CBM) are important energy reserves for unconventional natural gas. Thus, to investigate biogenic gas formation mechanisms, a series of fresh coal samples from several representative areas of ...
