Alkalotolerant and Alkalophilic Bacteria in Seawater
Numerous alkalotolerant and alkalophilic bacteria, with concentrations ranging from 10 to 103 cells 100 ml-' water sample, were isolated from seawater in the Pacific and Indian Oceans using a buffered medium of pH 10.6. The pH effects on growth rates were used to define the occurrence of three types of alkalotolerant and alkalophilic bacterial groups: (1) bacteria exhibiting high growth rates t...
متن کاملProton-Electrostatic Localization: Explaining the Bioenergetic Conundrum in Alkalophilic Bacteria
The decades-longstanding energetic conundrum of alkalophilic bacteria as to how they are able to synthesize ATP has now, for the first time, been clearly solved using the proton-electrostatics localization hypothesis [Bioenergetics 1:104; doi:10.4172/2167-7662.1000104]. This is a major breakthrough advance in understanding proton-coupling bioenergetics over the Nobel-prize work of Peter Mitchel...
متن کاملDegumming of ramie fibers by alkalophilic bacteria and their polysaccharide-degrading enzymes.
Three strains of alkalophilic bacteria, Bacillus sp. NT-39, NT-53 and NT-76, were selected for the degumming of ramie fibers and production of polysaccharide-degrading enzymes. After 48 h of incubation with the strains, the loss of the gum might amount to 5.0% or more of the fibers and a number of polysaccharide-degrading enzymes were secreted to the culture supernatants. The residual gum of th...
متن کاملAlkaline pH homeostasis in bacteria: new insights.
The capacity of bacteria to survive and grow at alkaline pH values is of widespread importance in the epidemiology of pathogenic bacteria, in remediation and industrial settings, as well as in marine, plant-associated and extremely alkaline ecological niches. Alkali-tolerance and alkaliphily, in turn, strongly depend upon mechanisms for alkaline pH homeostasis, as shown in pH shift experiments ...
متن کاملAnalysis on evolutionary relationship of amylases from archaea, bacteria and eukaryota
Amylase is one of the earliest characterized enzymes and has many applications in clinical and industrial settings. In biotechnological industries, the amylase activity is enhanced through modifying amylase structure and through cloning and expressing targeted amylases in different species. It is important to understand how engineered amylases can survive from generation to generation. This stu...
