Phylogeny of Dissimilatory Sulfite Reductases Supports an Early Origin of Sulfate Respiration
It is concluded that the high similarity of bacterial and archaeal DSRs reflects their common origin from a conserved DSR, which was either present before the split between the domains Bacteria, Archaea, and Eucarya or laterally transferred between Bacteria and Archaea soon after domain divergence.

Biodegradation of trichloroethylene by Methylosinus trichosporium OB3b
Cells capable oxidizing trichloroethylene contained components of soluble methane monooxygenase as demonstrated by Western blot (immunoblot) analysis with antibodies prepared against the purified enzyme. Expand
Optimization of trichloroethylene oxidation by methanotrophs and the use of a colorimetric assay to detect soluble methane monooxygenase activity
Methylosinus trichosporium OB3b biosynthesizes a broad specificity soluble methane monooxygenase that rapidly oxidizes trichloroethylene (TCE) and test several methanotrophic bacteria for the ability to oxidize TCE and naphthalene. Expand
Phylogenetic analysis and development of probes for differentiating methylotrophic bacteria
Fifteen small-subunit rRNAs from methylotrophic bacteria have been sequenced. Comparisons of these sequences with 22 previously published sequences further defined the phylogenetic relationshipsExpand
Survey of microbial oxygenases: trichloroethylene degradation by propane-oxidizing bacteria
The results indicated that TCE oxidation is not a common property of broad-specificity microbial oxygenases and one new unique class of microorganisms removed TCE from incubation mixtures. Expand
Use of 16S rRNA analysis to investigate phylogeny of methylotrophic bacteria.
Small-subunit rRNAS from 24 gran-negative methylotropic bacteria have been sequenced. A phylogenetic tree was constructed on the basis of sequence similarities by using a weighted least-mean-squareExpand
Biodegradation of low-molecular-weight halogenated hydrocarbons by methanotrophic bacteria.
The methanotrophic bacterium Methylosinus trichosporium 0B3b degrades trichloroethylene more rapidly than other bacteria examined to date and expression of soluble methane monooxygenase (MMO) is correlated with high rates of biodegradation. Expand
Characterization of a methane-utilizing bacterium from a bacterial consortium that rapidly degrades trichloroethylene and chloroform
It was concluded that a type II methanotrophic bacterium phylogenetically related to Methylosinus species synthesizes soluble methane monooxygenase and is responsible for trichloroethylene oxidation in the bioreactor. Expand
Addressing the Microbial Ecology of Marine Biofilms
Stated simply, biofilms are microorganisms attached to a solid surface. Biofilms pervade virtually all environments, often dominating the microbial activity distributed between the individualExpand
