Stable-isotope probing implicates Methylophaga spp and novel Gammaproteobacteria in marine methanol and methylamine metabolism

Predominant DGGE phylotypes, 16S rRNA, methanol and methylamine dehydrogenase gene sequences, and cultured isolates all implicated Methylophaga spp, moderately halophilic marine methylotrophs, in the consumption of both methnol and methamphetamine in coastal sea water.

An evaluation of Thiomicrospira, Hydrogenovibrio and Thioalkalimicrobium: reclassification of four species of Thiomicrospira to each Thiomicrorhabdus gen. nov. and Hydrogenovibrio, and…

It is demonstrated that Thioalkalimicrobium species fall within the genus Thiomicrospira sensu stricto, thus reclassifying them as Tms.

Active methylotrophs in the sediments of Lonar Lake, a saline and alkaline ecosystem formed by meteor impact

This study represents an essential first step towards understanding the relevance of methylotrophy in the soda lake sediments of an unusual impact crater structure and identifies active methylotrophic communities in methane, methanol and methylamine SIP microcosms.

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere.

Current knowledge on the microbial cycling of DMS is examined and areas for future research are pointed out that should shed more light on the role of organisms degrading DMS and related compounds in the biosphere.

Oxidation of dimethylsulfide to tetrathionate by Methylophaga thiooxidans sp. nov.: a new link in the sulfur cycle.

The production of tetrathionate from an organosulfur precursor is previously undocumented and represents a potential step in the biogeochemical sulfur cycle, providing a 'shunt' across the cycle.

  • 8 September 2017
A polyphasic study was undertaken to determine if these two species of obligate autotrophs represent a separate genus and it is proposed that they be circumscribed as a new genus Guyparkeria gen. nov, for which Thioalkalibacter is the type genus.

Substrate-Specific Clades of Active Marine Methylotrophs Associated with a Phytoplankton Bloom in a Temperate Coastal Environment

This study expands the known diversity of marine methylotrophs in surface seawater and provides a comprehensive data set for focused cultivation and metagenomic analyses in the future.

Purification and Characterization of Dimethylsulfide Monooxygenase from Hyphomicrobium sulfonivorans

DMS monooxygenase represents a new class of FMNH₂-dependent Monooxygenases, based on its specificity for dimethylsulfide and the molecular phylogeny of its predicted amino acid sequence.

Reclassification of Thiobacillus aquaesulis (Wood & Kelly, 1995) as Annwoodia aquaesulis gen. nov., comb. nov., transfer of Thiobacillus (Beijerinck, 1904) from the Hydrogenophilales to the…

The genus Thiobacillus is proposed to be moved to a novel genus, Annwoodia aquaesulis gen. nov, and the Hydrogenophilales from the Betaproteobacteria is rejected on the basis of a very low 16S rRNA gene sequence similarity with the class-proper as well as physiological properties, forming the Hydrogensophilalia class.
