【摘要】RpoS(σs或σ38)是迄今发现的E.coli的7种转录起始因子之一,可在E.coli生长率下降、进入静止期或受到饥饿、热击、低温、高渗、氧化等环境压力时被诱导表达,从而或直接或间接的促进或抑制上千个基因的转录,以使E.coli能够对(现存和未来可能遇到的)多种环境压力做出响应。RpoS主导的一般压力反应伴有能耗且...
E. coliMPP+ and paraquat (PQ+2) are two structurally analogous and highly toxic pyridinium compounds. The mechanism of PQ+2 toxicity is best understood in the bacterial model system. While numerous studies, in a variety of systems, have indicated the causative role of free radicals and other...
This work demonstrates such a workflow, aimed at establishing a metabolomics platform applied to study the differences in metabolomes between anaerobic and aerobic growth of Escherichia coli. Constraint-based modeling was utilized to deduce a target list of compounds for downstream method development. An...
Aerobic and anaerobic metabolism during activity in the lizardDipsosaurus dorsalis 1. Oxygen consumption and lactate content of the lizard Dipsosaurus dorsalis were determined under standard conditions and for a bout of maximal activity induced by a 2-min period of electrical stimulation. Observations ...
A novel aerobic/anaerobic/aerobic treatment was implemented in batch reactors containing aquifer materials from a site contaminated by tetrachloroethylene (PCE), trichloroethylene (TCE), vinyl chloride (VC), 1,1,2-trichloroethane (1,1,2-TCA) and chloroform (CF). Consortia grown aerobically on metha...
Here, we introduce a mechanism of anaerobic biofilm formation by investigating the antibiofilm activity of tyrosol, a component in wine. Tyrosol inhibits E. coli and Pseudomonas aeruginosa biofilm formation by enhancing NO production. YbfA is identified as a target of tyrosol and its downstream ...
These compounds are used as electron donors for anaerobic phototrophic and aerobic chemotrophic growth, and are mostly oxidized to sulfate... CG Friedrich - 《Advances in Microbial Physiology》 被引量: 336发表: 1997年 Aerobic bacterial pyrite oxidation and acid rock drainage during ...
coli can be spread through feces as the bacteria pass out of the body. These two habitats are about as opposite as you can get. The colon is relatively stable, warm, anaerobic, and nutrient-rich. Outside of the colon, conditions can be extremely harsh and variable, much colder, aerobic,...

aThus, biological treatment composed of anaerobic-anaerobic-aerobic MBBR using PU-AC foam as carrier is a viable technique for dyeing wastewater treatment without using further chemical treatment (e.g., coagulation and flocculation). 因此,生物治疗组成由绝氧绝氧有氧MBBR使用PU-AC泡沫作为载体是洗染废水...
