Transcriptome Profiling of the Response of Arabidopsis Suspension Culture Cells to Suc Starvation1[w]

Upon encountering nutrient stress conditions, plant cells undergo extensive metabolic changes and induce nutrient recycling pathways for their continued survival. The role of nutrient mobilization in…

Altererythrobacter epoxidivorans gen. nov., sp. nov., an epoxide hydrolase-active, mesophilic marine bacterium isolated from cold-seep sediment, and reclassification of Erythrobacter luteolus Yoon et…

On the basis of the evidence of this polyphasic taxonomic study, strain JCS350(T) should be classified in a novel genus and species in the family Erythrobacteraceae, for which the name Altereryth Robacter epoxidivorans gen. nov. is proposed.

Novosphingobium pentaromativorans sp. nov., a high-molecular-mass polycyclic aromatic hydrocarbon-degrading bacterium isolated from estuarine sediment.

A Gram-negative, yellow-pigmented, halophilic bacterial strain US6-1T, which degrades high-molecular-mass polycyclic aromatic hydrocarbons of two to five rings, was isolated from muddy sediment of Ulsan Bay, Republic of Korea and is proposed to represent a novel species in the genus Novosphingobium.

Minke whale genome and aquatic adaptation in cetaceans

Overall the whale-genome sequences exhibited distinct features that are associated with the physiological and morphological changes needed for life in an aquatic environment, marked by resistance to physiological stresses caused by a lack of oxygen, increased amounts of reactive oxygen species and high salt levels.

Purification and characterization of NADPH-dependent Cr(VI) reductase from Escherichia coli ATCC 33456.

A soluble Cr(VI) reductase was purified from the cytoplasm of Escherichia coli ATCC 33456, and the activity was strongly inhibited by N-ethylmalemide, Ag2+, Cd2+, Hg2+, and Zn2+.

Microbial Decomposition in Aquatic Environments: Combined Process of Extracellular Enzyme Activity and Substrate Uptake

A model for the coupling between extracellular enzyme activity and substrate uptake by bacterial populations in natural waters is defined and it was found that turnover rates of leucine and hydrolysis rates of Leu-MCA, as well as the quotient T(r)/H(r), reflect the impact of environmental conditions on decomposition processes at both sampling sites.
