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

Methanogenic \u3cem\u3eArchaea\u3c/em\u3e and human periodontal disease [PDF]
, 2004 Archaea have been isolated from the human colon, vagina, and oral cavity, but have not been established as causes of human disease. In this study, we reveal a relationship between the severity of periodontal disease and the relative abundance of archaeal

A proposal for climate stability on H2-greenhouse planets
, 2015 A terrestrial planet in an orbit far outside of the standard habitable zone could maintain surface liquid water as a result of H2-H2 collision-induced absorption by a thick H2 atmosphere.

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]
, 2010 Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

An identity card for sabkha dolomite
The Depositional Record, Volume 12, Issue 1, February 2026.An ‘identity card’ for modern sabkha dolomite from Qatar reveals its mineralogical, geochemical and microbial characteristics. This integrated dataset provides a benchmark for recognising similar dolomites in the rock record and for calibrating paleoenvironmental proxies used in climate and biosignature studies.

Food Science &Nutrition, Volume 14, Issue 2, February 2026.The graphical abstract illustrates the conversion of food waste biomass into bioethanol through integrated pretreatment strategies. Physical (mechanical, thermal, sonication), chemical (alkali, acidic, oxidative/ROS), and biological (fungal, bacterial, enzymatic) pretreatments enhance biomass breakdown.

Relating Methanogen Community Structure and Anaerobic Digester Function [PDF]
, 2015 Much remains unknown about the relationships between microbial community structure and anaerobic digester function. However, knowledge of links between community structure and function, such as specific methanogenic activity (SMA) and COD removal rate ...

User-friendly mathematical model for the design of sulfate reducing H2/CO2 fed bioreactors [PDF]
, 2009 The paper presents three steady-state mathematical models for the design of H2/CO2 fed gas-lift reactors aimed at biological sulfate reduction to remove sulfate from wastewater. Models 1A and 1B are based on heterotrophic sulfate reducing bacteria (HSRB),

Methanogens dominate methanotrophs and act as a methane source in aquaculture pond sediments
Ecotoxicology and Environmental SafetyAquaculture pond sediments act as hotspots for methane (CH4) emissions; however, knowledge gaps on the regulation of microorganisms hinder our further understanding of methane dynamics in aquaculture pond sediment.
