Cycloclasticus sp. strain P1 was isolated from deep-sea sediments of the Pacific Ocean and characterized as a unique bacterium in the degradation of pyrene, a four-ring polycyclic aromatic hydrocarbon (PAH). Here we report the complete genome of P1 and genes associated with PAH degradation.

Sphingobium sp. 22B is a polycyclic aromatic hydrocarbon-degrading strain isolated from Patagonia, Argentina, with capabilities to withstand the environmental factors of that semiarid region. The draft genome shows the presence of genes related with responses to carbon starvation and drying environmental conditions.

Retene, dehydroabietin, and 1,2,3,4-tetrahydroretene have been identi®ed by GC±MS in extractable aromatic hydrocarbon fractions produced by pyrolysis at 200 and 300 C of pure strains of the green alga Chlorella protothecoides and the cyanobacterium Synechocystis sp. The results suggest phytoplankton as a possible source of retene in Recent and ancient sediments. # 2000 Elsevier Science Ltd. All...

Pseudomonas sp. strain Ant30-3, isolated from fuel-contaminated Antarctic soil, exhibited distinctive psychrotolerant attributes and the potential for degrading aromatic hydrocarbon compounds at cold temperatures. We report here the 6.14-Mb draft genome of Ant30-3, which will provide insights into the genomic basis for the psychrotolerant and biodegradative properties of this bacterium.

Two yeast strains are enriched and isolated from industrial refinery wastewater. These strains were observed for their ability to utilize several classes of petroleum hydrocarbons substrates, such as n-alkanes and aromatic hydrocarbons as a sole carbon source. Phylogenetic analysis based on the D1/D2 variable domain and the ITS-region sequences indicated that strains HC1 and HC4 were members of...

Two-dimensional (2D) nucleation and crystallization of the helical aromatic hydrocarbon heptahelicene on the single crystalline copper(100) surface has been studied with scanning tunnelling microscopy. In contrast to previously observed racemic 2D crystals on Cu(111), separation into homochiral domains is observed for Cu(100).

Pannonibacter phragmitetus CGMCC9175 is a halotolerant polycyclic aromatic hydrocarbon (PAH)-degrading bacterium isolated from PAH-contaminated intertidal zone sediment. Here, we report the 5.7-Mb draft genome sequence of this strain, which will provide insights into the diversity of Pannonibacter and the mechanism of PAH degradation in sediments.
