Methanosarcina thermophila bioaugmentation and its synergy with biochar growth support particles versus polypropylene microplastics in thermophilic food waste anaerobic digestion.

Bioresource Technology, 2022
Both biochar supplementation as well as bioaugmentation have been shown in literature to improve the methane yield of anaerobic digestion. In this study, the combination of both are evaluated by growing Methanosarcina thermophila on biochar support ...

Bioaugmentation of Methanosarcina thermophila grown on biochar particles during semi-continuous thermophilic food waste anaerobic digestion under two different bioaugmentation regimes.

Bioresource Technology, 2022
This study presents the effect of bioaugmentation of thermophilic anaerobic digestion of food waste with Methanosarcina thermophila grown on a wood-derived biochar. Two different supplementation regimes were tested, namely a single bioaugmentation (SBABC)

Metabolic Regulation of Mesophilic Methanosarcina barkeri to Ammonium Inhibition.

Environmental Science and Technology, 2022
Undesirable ammonium concentrations can lead to unstable anaerobic digestion processes, and Methanosarcina spp. are the representative methanogens under inhibition.

Genetic Methods for Methanosarcina Species

2011
Unlike most methanogenic microorganisms, Methanosarcina species are capable of utilizing a variety of growth substrates, a trait that greatly simplifies genetic analysis of the methanogenic process. The genetic tools and techniques discussed in this chapter form the basis for all genetic experiments in Methanosarcina acetivorans C2A and Methanosarcina ...

Mixotrophic growth of two thermophilic Methanosarcina strains, Methanosarcina thermophila TM-1 and Methanosarcina sp. SO-2P, on methanol and hydrogen/carbon dioxide

Applied Microbiology and Biotechnology, 1997
Two thermophilic strains, Methanosarcina thermophila TM-1 and Methanosarcina sp. SO-2P, were capable of mixotrophic growth on methanol and H2/CO2. Activated carbon was, however, found to be necessary to support good growth. Both strains used hydrogen and methanol simultaneously. When methanol was depleted, hydrogen utilization continued and methane was

Redox Cycling of Fe(II) and Fe(III) in Magnetite Accelerates Aceticlastic Methanogenesis by Methanosarcina mazei.

Environmental Microbiology Reports, 2019
It has been recently shown that magnetite nanoparticles (nanoFe3 O4 ) can facilitate methanogenic syntrophy but the effect of magnetite on methanogenesis alone remains elusive.

Two F 420 -reducing hydrogenases in Methanosarcina barkeri

Archives of Microbiology, 1998
F420-reducing hydrogenases are nickel iron-sulfur flavoproteins involved in CO2 reduction with H2 to methane in methanogenic archaea. Evidence is presented that Methanosarcina barkeri contains two isoenzymes for which the encoding genes have been cloned and sequenced.

Reductive nitrosylation of Methanosarcina acetivorans protoglobin: A comparative study

Biochemical and Biophysical Research Communications, 2013
Methanosarcina acetivorans is a strictly anaerobic non-motile methane-producing Archaea expressing protoglobin (Pgb) which might either facilitate O(2) detoxification or act as a CO sensor/supplier in methanogenesis. Unusually, M. acetivorans Pgb (MaPgb) binds preferentially O(2) rather than CO and displays anticooperativity in ligand binding.
