Introducing ectoine as compatible solute: biosynthetic pathway, production and applications
Halophilic microorganisms cope with environmental stresses by producing and accumulating compatible solutes. Ectoine is one of the most important members of compatible solutes which have extra protective properties compared to other compatible solutes. Ectoine attracts several scientific and commercial attention because of their multiple industrial applications. This brief review presents appli...
متن کاملGlucosylglycerol, a compatible solute, sustains cell division under salt stress.
The cyanobacterium Synechocystis sp. PCC 6803 accumulates the compatible solute glucosylglycerol (GG) and sucrose under salt stress. Although the molecular mechanisms for GG synthesis including regulation of the GG-phosphate synthase (ggpS) gene, which encodes GgpS, has been intensively investigated, the role of GG in protection against salt stress remains poorly understood. In our study of the...
متن کاملRegulation of compatible solute accumulation in bacteria.
In their natural habitats, microorganisms are often exposed to osmolality changes in the environment. The osmotic stress must be sensed and converted into an activity change of specific enzymes and transport proteins and/or it must trigger their synthesis such that the osmotic imbalance can be rapidly restored. On the basis of the available literature, we conclude that representative gram-negat...
متن کاملGlycine betaine catabolism contributes to Pseudomonas syringae tolerance to hyperosmotic stress by relieving betaine-mediated suppression of compatible solute synthesis.
Many bacteria can accumulate glycine betaine for osmoprotection and catabolize it as a growth substrate, but how they regulate these opposing roles is poorly understood. In Pseudomonas syringae B728a, expression of the betaine catabolism genes was reduced by an osmotic upshift to an intermediate stress level, consistent with betaine accumulation, but was increased by an upshift to a high stress...
متن کاملMannitol, a novel bacterial compatible solute in Pseudomonas putida S12.
The aim of this study was to identify the compatible solutes accumulated by Pseudomonas putida S12 subjected to osmotic stress. In response to reduced water activity, P. putida S12 accumulated Nalpha-acetylglutaminylglutamine amide (NAGGN) simultaneously with a novel compatible solute identified as mannitol (using 13C- and 1H-nuclear magnetic resonance, liquid chromatography-mass spectroscopy a...
