Rene L Hoover
To understand the ecophysiology and the role of iron-oxidizing bacteria (FeOB) in various ecosystems, we need to identify marker genes of the iron oxidation pathway to track activity in situ. The Gallionellaceae Sideroxydans sp. CL21, an au...
Sporulation kinetics of Bacillus subtilis under pH shift conditions: impact on spore properties and gene expression [0.03%]
芽孢杆菌在pH变化条件下的芽孢形成动力学及其对芽孢性质和基因表达的影响
Kaoutar Hafdane,Noémie Desriac,Clément Trunet et al.
Kaoutar Hafdane et al.
Bacterial spores are highly resistant to environmental stresses, which limits the efficiency of decontamination processes and increases the risk of spoilage and foodborne illness. While pH is a key factor influencing sporulation efficiency ...
Biochemical characterization and X-ray structural and mutagenic analyses of the putative autolysin CdCwlT33800 catalytic domain from Clostridioides difficile [0.03%]

Hiroshi Sekiya,Yasuhiro Nonaka,Shigehiro Kamitori et al.
Hiroshi Sekiya et al.
Clostridioides difficile is a major pathogen of pseudomembranous colitis, and new antimicrobial agents are needed for its treatment. Autolysins are peptidoglycan-degrading enzymes that generally reorganize the cell wall during cell division...
Transcriptomic profiling of Debaryomyces hansenii reveals detoxification and stress responses to benzo(a)pyrene exposure [0.03%]
转录组分析揭示德巴利酵母对苯并(a)芘暴露的解毒和应激反应
