The first microbial rhodopsin, a light-driven proton pump bacteriorhodopsin from Halobacterium salinarum (HsBR), was discovered in 1971. Since then, this seven-α-helical protein, comprising a retinal molecule as a cofactor, became a major driver of groundbreaking developments in membrane protein research.

Mass spectrometry-based "-omics" technologies are important tools for global and detailed mapping of post-translational modifications. Protein glycosylation is an abundant and important post translational modification widespread throughout all domains of life.

Temperature is among the most important of the parameters that free-living microbes monitor. Microbial physiology needs to be readjusted in response to sudden temperature changes. When the ambient temperature rises or drops to potentially harmful levels, cells mount protective stress responses--so-called heat or cold shock responses, respectively ...

Xanthophylls are oxygenated carotenoids abundant in the human food supply. Lutein, zeaxanthin, and cryptoxanthin are major xanthophyll carotenoids in human plasma. The consumption of these xanthophylls is directly associated with reduction in the risk of cancers, cardiovascular disease, age-related macular degeneration, and cataract formation ...

Bacterial metallothioneins bind, sequester and buffer excess intracellular zinc. At present, the vast majority of the available experimental data relate to cyanobacterial metallothionein, SmtA, from Synechococcus PCC 7942. SmtA is required for normal resistance to zinc and smtA-mediated zinc resistance has been used as a selectable marker.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1980 An understanding of the mechanisms by which bacteria derive their energy is clearly important for the prediction of growth yields. Bacteria can synthesize ATP by a variety of routes, by fermentation, by oxidative phosphorylation, and possibly by the excretion of metabolic end products. The bacterium Escherichia coli

crobial mats are laminated microbial communities that generally develop in aqueous environments under conditions that exclude fauna. The biogeochemical cycles in microbial mats are usually largely closed, although small fluxes of elements are exchanged with the geo-, bio-, and atmosphere.

Microbial systematics and taxonomy: relevance for a microbial commons
Research in Microbiology, 2010The issues of microbial taxonomy and potential interactions with a microbial commons are discussed, with emphasis on three components: characterization; classification; and nomenclature. The current state of technology and the spectrum of methods that are used for phenotypic and genotypic characterization of prokaryotes, classification at different ...

The article discusses a lack of knowledge among scientists on how antibiotics work. Topics include a study by biomedical engineer James Collins at Boston University that suggests antibiotics increase bacterial levels of reactive oxygen species, fatally corroding the bacteria's DNA and studies by genome scientist Colin Manoil at the University of ...
