Anaerobic Digestion Technology for Methane Production Using Deer Manure Under Different Experimental Conditions

Energies, 2019
Anaerobic digestion (AD) is an important technology for the treatment of livestock and poultry manure. The optimal experimental conditions were studied, with deer manure as a fermentation material and mushroom residue as an inoculum.

Evaluation of the methane paradox in four adjacent pre-alpine lakes across a trophic gradient

Nature Communications, 2023
Contrasting the paradigm that methane is only produced in anoxic conditions, recent discoveries show that oxic methane production (OMP, aka the methane paradox) occurs in oxygenated surface waters worldwide.

Production of Bacterial Cells from Methane [PDF]

Applied Microbiology, 1971
A mixed methane-oxidizing bacterial culture capable of stable and predictable growth in continuous culture was isolated. The culture consisted of two types of gram-negative nonsporulating rods resembling pseudomonads. The culture grew well at 45 C on an inorganic medium without asepsis. Specific metal requirements for Ca 2+

Development and Application of Dual-Tubing Jet Pump Full-Process Pressure-Maintained Drainage String in Deep Coal-Rock Gas Wells

Shiyou jixie
Deep coal-rock gas reservoir is sensitive to downhole pressure variation， and implementing kill operation may cause damage to gas production. Consequently， a full-process pressure-maintained operation technique of dual-tubing jet pump for deep coal-rock ...

Evidence for methane production by saprotrophic fungi [PDF]

Nature Communications, 2012
Methane in the biosphere is mainly produced by prokaryotic methanogenic archaea, biomass burning, coal and oil extraction, and to a lesser extent by eukaryotic plants. Here we demonstrate that saprotrophic fungi produce methane without the involvement of methanogenic archaea.

Methyl fluoride, an inhibitor of methane oxidation and methane production [PDF]

FEMS Microbiology Ecology, 1996
Abstract Methyl fluoride (CH 3 F) has been reported to inhibit effectively aerobic CH 4 oxidation, while not affecting methanogenesis. Currently it is applied in a variety of ecosystems, where oxidation and production of CH 4 take place simultaneously.
