More than 70 species of halotolerant and halophilic actinomycetes belonging to at least 24 genera have been validly described. Halophilic actinomycetes are a less explored source of actinomycetes for discovery of novel bioactive secondary m...
Purification and biochemical characterisation of a glucose-6-phosphate dehydrogenase from the psychrophilic green alga Koliella antarctica [0.03%]
来自 Antarcticia koliella 的葡萄糖-6-磷酸脱氢酶的提纯及生化性质表征

Heat- and solvent-tolerant enzymes from halophiles, potentially important industrially, offer a robust framework for protein engineering, but few solved halophilic structures exist to guide this. Homology modelling has guided mutations in g...
A hydrolytic γ-glutamyl transpeptidase from thermo-acidophilic archaeon Picrophilus torridus: binding pocket mutagenesis and transpeptidation [0.03%]
来源于嗜酸热栖菌Picrophilus torridus的水解型γ-谷氨酰转肽酶：结合袋诱变和转肽作用

A wide variety of microhabitats within the extremely acidic abandoned underground copper mine Zlaté Hory (Czech Republic) was investigated. SSU rDNA libraries were analyzed from 15 samples representing gossan, sulfide-leaching environments...
Distribution of CO(2) fixation and acetate mineralization pathways in microorganisms from extremophilic anaerobic biotopes [0.03%]
极端厌氧生物群落中微生物的CO₂固定和醋酸盐矿化途径分布
Lilia Montoya,Lourdes B Celis,Elías Razo-Flores et al.
Lilia Montoya et al.
Extremophilic anaerobes are widespread in saline, acid, alkaline, and high or low temperature environments. Carbon is essential to living organisms and its fixation, degradation, or mineralization is driven by, up to now, six metabolic path...
