Microbial cycling of volatile organic sulfur compounds
TLDR
Inhibition studies have revealed that the major part of the endogenously produced MT and DMS is degraded anaerobically by methanogens, and the major bacterial groups involved in formation and consumption of VOSCs are described. Expand
Isolation and Characterization of Methanomethylovorans hollandica gen. nov., sp. nov., Isolated from Freshwater Sediment, a Methylotrophic Methanogen Able To Grow on Dimethyl Sulfide and Methanethiol
TLDR
It is proposed that strain DMS1T is a representative of a novel genus which was directly enriched and isolated from a freshwater sediment in defined minimal medium containing dimethyl sulfide as the sole carbon and energy source and was named Methanomethylovorans hollandica. Expand
Formation of dimethyl sulfide and methanethiol in anoxic freshwater sediments.
TLDR
Findings and the observed stimulation of methanethiol formation in sediment slurry incubations provided strong evidence that the anaerobic methylation of hydrogen sulfide is the main mechanism for VOSC formation in most freshwater systems. Expand
Promicromonospora pachnodae sp. nov., a member of the (hemi)cellulolytic hindgut flora of larvae of the scarab beetle Pachnoda marginata
TLDR
Comparative 16S rDNA analysis and phenotypic features revealed that the isolate represented a new species for which the name Promicromonospora pachnodae is proposed, both under aerobic and anaerobic conditions. Expand
Effect of Host Diet and Hindgut Microbial Composition on Cellulolytic Activity in the Hindgut of the American Cockroach, Periplaneta americana.
TLDR
A close correlation was found between the number of Nyctotherus ovalis organisms, the major protozoans in the hindgut, and both FPase and CMCase activity, and it appears that N. ovalis is responsible for the major part of cellulolytic and methanogenic activity found in the hindergut of P. americana. Expand
Involvement of an activation protein in the methanol:2-mercaptoethanesulfonic acid methyltransferase reaction in Methanosarcina barkeri.
TLDR
The finding that one more protein fraction was found essential for the overall reaction and, more specifically, for formation of the methylated MT1 intermediate demonstrated that the protein was involved in the activation of MT1 and was called methyltransferase activation protein. Expand
A protonmotive force drives bacterial flagella.
TLDR
It is concluded that the flagella are driven by a protonmotive force, and when starved cells are suspended in a potassium-free medium containing both valinomycin and an attractant, many cells initially run rather than twiddle. Expand
Degradation of purines and pyrimidines by microorganisms.

Bacteria in the Intestinal Tract of Different Species of Arthropods
TLDR
The population of bacteria in some parts of the intestinal tract of several arthropods were high enough to suggest a potential contribution to digestive processes. Expand
Microbial Populations Involved in Cycling of Dimethyl Sulfide and Methanethiol in Freshwater Sediments
TLDR
The data from sediment incubation experiments, MPN series, and molecular-genetics detection correlated well and provide convincing evidence for the suggested mechanisms for MT and DMS cycling and the common presence of the DMS-degrading methanogen M. hollandica in freshwater sediments. Expand
