Exploring new fields: Lanthanide-using bacteria that turn over methane or methanol in their metabolism can replace essential lanthanides by certain actinides. In Research Article (e202303669), Lena J. Daumann et al. show an extremophile isolated from a volcanic mud-pot as well methylotrophic laboratory strain use americium and curium. vivo growth experiments vitro studies with the key metabolic...

Methylobacterium species are representative of methylotrophic bacteria. Their genomes usually encode two types of methanol dehydrogenases (MDHs): MxaF and XoxF. The former is a Ca2+-dependent enzyme, and the latter was recently determined to be a lanthanide-dependent enzyme that is necessary for the expression of mxaF. This finding revealed the unexpected and important roles of lanthanides in b...

Methanogenic archaeon ISO4-G1 is a methylotrophic methanogen belonging to the orderMethanomassiliicoccalesthat was isolated from a sheep rumen. Its genome has been sequenced to provide information on the genetic diversity of rumen methanogens in order to develop technologies for ruminant methane mitigation.

Cell-free particulate fractions derived from methylotrophic bacteria catalyze the oxygen- and reduced nicotinamide adenine dinucleotide-dependent epoxidation of alkenes and hydroxylation of alkanes. Evidence presented indicates that the hydroxylation and epoxidation reactions are catalyzed by the same or a similar metal-containing monooxygenase.

Methylophaga aminisulfidivorans MP(T) is a restricted facultatively marine methylotrophic bacterium that grows on methanol, methylated amines, dimethyl sulfide, and dimethyl sulfoxide. Here we present the high-quality draft genome sequence of M. aminisulfidivorans MP(T) (KCTC 12909(T) = JCM 14647(T)), consisting of a chromosome (3,092,085 bp) and a plasmid (16,875 bp).

Two aerobic, pink-pigmented, facultatively methylotrophic bacteria, strains F20T and RXM(T), are described taxonomically. On the basis of their phenotypic and genotypic properties, the isolates are proposed as novel species of the genus Methylobacterium, Methylobacterium suomiense sp. nov. (type strain F20T = VKM B-2238T = NCIMB 13778T) and Methylobacterium lusitanum sp. nov. (type strain RXMT ...
