Morphology and Phylogeny of a New Species of Anaerobic Ciliate, Trimyema finlayi n. sp., with Endosymbiotic Methanogens

Frontiers in Microbiology, 2018
Many anaerobic ciliated protozoa contain organelles of mitochondrial ancestry called hydrogenosomes. These organelles generate molecular hydrogen that is consumed by methanogenic Archaea, living in endosymbiosis within many of these ciliates.

Ecological and Technological Insights to Enhance Rice Production: A Machine Learning Approach for Sustainable Agriculture in Granma, Cuba

Sustainable Development, EarlyView.
ABSTRACT Amid the quest for sustainable agriculture, this study explores key ecological and technological factors influencing crop production under climate change. We conduct a comprehensive assessment of temperature, biomass, farmer education, renewable energy devices, greenhouse gas emissions and their effects on rice yields in Granma, Cuba, from ...

Responses of methanogenic and methanotrophic communities to elevated atmospheric CO2 and temperature in a paddy field

Frontiers in Microbiology, 2016
Although climate change is predicted to affect methane (CH4) emissions in paddy soil, the dynamics of methanogens and methanotrophs in paddy fields under climate change have not yet been fully investigated.

Cryptic Methane-Cycling by Methanogens During Multi-Year Incubation of Estuarine Sediment

Frontiers in Microbiology, 2022
As marine sediments are buried, microbial communities transition from sulfate-reduction to methane-production after sulfate is depleted. When this biogenic methane diffuses into the overlying sulfate-rich sediments, it forms a sulfate-methane transition ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

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

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

Agricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Environmental drivers of gaseous carbon fluxes in drained and rewetted Minnesota peatlands, U. S. A.

Restoration Ecology, EarlyView.
Abstract Introduction Rewetting shows promise for mitigating carbon loss from drained peatlands. However, knowledge gaps remain in rewetting impacts on gaseous carbon fluxes and factors affecting rewetting success, especially in Minnesota and the Upper Midwest, United States, despite abundant degraded peatlands presenting restoration opportunities ...
