Substantial spatial variability in the degradation rate of the phenyl-urea herbicide isoproturon (IPU) [3-(4-isopropylphenyl)-1,1-dimethylurea] has been shown to occur within agricultural fields, with implications for the longevity of the compound in the soil, and its movement to ground- and surface water. The microbial mechanisms underlying such spatial variability in degradation rate were inv...

Pseudomonas sp. strain YS-1p and Rhizobium sp. strain YS-1r were isolated from a lignin-degrading enrichment culture. The isolates degraded lignin-derived monomers, dimers, alkali lignin, and, to a smaller extent (3% to 5%), lignin in switch grass and alfalfa. Genome analysis revealed the presence of a variety of lignin-degrading genes.

Pseudomonas psychrophila HA-4 is a cold-adaptable, sulfamethoxazole-degrading bacterium. The genes related to its cold adaptation mechanism and sulfamethoxazole metabolism were unknown. We present the draft genome of strain HA-4. It could provide further insight into the sulfamethoxazole-degrading mechanism of strain HA-4.

We report the draft genome sequence of the cellulose-degrading bacterium Clostridium papyrosolvens C7, originally isolated from mud collected below a freshwater pond in Massachusetts. This Gram-positive bacterium grows in a mesophilic anaerobic environment with filter paper as the only carbon source, and it has a simple cellulosome system with multiple carbohydrate-degrading enzymes.

Here we report the development of a whole-cell biosensor to detect and quantify the induction of the SOS response activated by DNA-degrading colicins. This biosensor utilizes the SOS-responsive cda promoter to regulate the expression of green fluorescent protein. The biosensor assay revealed induction of stress for all DNA-degrading reference colicins (E2, E7, and E8).

Alkanes comprise a substantial fraction of crude oil and are prevalent at marine seeps. These environments are typically anoxic and host diverse microbial communities that grow on alkanes. The most widely distributed mechanism of anaerobic alkane activation is the addition of alkanes to fumarate by (1-methylalkyl)succinate synthase (Mas). Here we studied the diversity of MasD, the catalytic sub...

The draft genome of an uncultivated bacterium affiliated with the Peptococcaceae was reconstructed by co-assembling Illumina MiSeq sequences from three single cells sorted by microfluidics from two methanogenic alkane-degrading cultures. Peptococcaceae SCADC (short-chain alkane-degrading culture) may be genetically capable of anaerobic alkane activation by fumarate addition in the absence of su...

Two novel methanesulfonate-degrading bacterial strains of "Candidatus Filomicrobium marinum" (strains Y and W) were isolated from a marine water enrichment, and their complete genome sequences are presented here. These are the first full genomes reported for the genus Filomicrobium and for methanesulfonate (MSA)-degrading bacteria.

We have developed a static analysis to help developers understand the interactions between objects and tasks in Bristlecone applications. The Bristlecone language was designed to help developers construct robust applications out of potentially unreliable components. Bristlecone applications can adapt their behavior, potentially degrading their functionality, in response to software errors in or...

Here, we report the draft genome sequence of Bacillus sp. strain GZT, a 2,4,6-tribromophenol (TBP)-degrading bacterium previously isolated from an electronic waste-dismantling region. The draft genome sequence is 5.18 Mb and has a G+C content of 35.1%. This is the first genome report of a brominated flame retardant-degrading strain.
