This review provides an overview of current knowledge concerning type IVb pili in Gram-negative bacteria. The number of these pili identified is steadily increasing with genome sequencing and mining studies, but studies of these pili are so...
Effects of intracellular poly(3-hydroxybutyrate) reserves on physiological-biochemical properties and growth of Ralstonia eutropha [0.03%]

Microbial polyhydroxyalkanoates (PHAs), because of their well studied complex physiology and commercial potential, are vehicles for carbon and potential storage reduction for many microbial species. Even with the wealth of studies about mic...
Thioridazine potentiates the effect of a beta-lactam antibiotic against Staphylococcus aureus independently of mecA expression [0.03%]
奋乃静通过独立于mecA表达的方式增强β-内酰胺抗生素对金黄色葡萄球菌的效果

Here we characterize the first step in methionine biosynthesis in Agrobacterium tumefaciens, an α-proteobacterium. We explored the metA gene and its products and found several unique properties. Although the gene was annotated as a homoser...
Mutation of crp mediates Serratia marcescens serralysin and global secreted protein production [0.03%]
crp基因突变介导了Serratia marcescens菌的serralysin和其他全局分泌蛋白的产生
Robert M Q Shanks,Nicholas A Stella,Kristin E Arena et al.
Robert M Q Shanks et al.
The bacterial species Serratia marcescens secretes both beneficial and cytotoxic proteins. Here we report that a crp mutant exhibited elevated secreted protease activity. A genetic screen revealed that the gene coding for the metalloproteas...
Colorimetric microbial diversity analysis and halotolerance along a soil salinity gradient at the Great Salt Plains of Oklahoma [0.03%]

Microbial diversity was measured along a salinity gradient at the Great Salt Plains of Oklahoma using colony color quantified as RGB components of microbial isolate streaks. Numerical taxonomy was performed using a UPGMA method to create tr...
Atomic force and super-resolution microscopy support a role for LapA as a cell-surface biofilm adhesin of Pseudomonas fluorescens [0.03%]
原子力和超分辨率显微术支持黄荧假单胞菌LapA作为细胞表面生物膜黏附蛋白的作用

Ivan E Ivanov et al.
Pseudomonas fluorescence Pf0-1 requires the large repeat protein LapA for stable surface attachment. This study presents direct evidence that LapA is a cell-surface-localized adhesin. Atomic force microscopy (AFM) revealed a significant 2-f...
Evidence of a plasmid-encoded oxidative xylose-catabolic pathway in Arthrobacter nicotinovorans pAO1 [0.03%]
葡萄糖球菌pAO1中尼古丁诱导的可移动遗传元件携带一个新的木糖氧化发酵途径

Due to its high abundance, the D-xylose fraction of lignocellulose provides a promising resource for production of various chemicals. Examples of efficient utilization of d-xylose are nevertheless rare, mainly due to the lack of enzymes wit...
Re-sequencing of a virulent strain of Campylobacter jejuni NCTC11168 reveals potential virulence factors [0.03%]
劳森菌NCTC11168毒力菌株的重新测序揭示了潜在的毒力因子

Kerry K Cooper et al.
In vitro passage of Campylobacter jejuni strains results in phenotypic changes and a general loss of virulence, as is the case with the genome-sequenced strain C. jejuni NCTC11168. Re-sequencing of a virulent strain of NCTC11168 identified ...
