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 کاملContinuous synthesis and excretion of the compatible solute ectoine by a transgenic, nonhalophilic bacterium.
The compatible solute 1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid (ectoine) acts in microorganisms as an osmotic counterweight against halostress and has attracted commercial attention as a protecting agent. Its production and application are restricted by the drawbacks of the discontinuous harvesting procedure involving salt shocks, which reduces volumetric yield, increases reactor...
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...
متن کاملOsmotically regulated synthesis of the compatible solute ectoine in Bacillus pasteurii and related Bacillus spp.
By using natural-abundance (13)C-nuclear magnetic resonance spectroscopy and high-performance liquid chromatography (HPLC) analysis we have investigated the types of compatible solutes that are synthesized de novo in a variety of Bacillus species under high-osmolality growth conditions. Five different patterns of compatible solute production were found among the 13 Bacillus species we studied. ...
متن کاملSynthesis of the compatible solute ectoine in Virgibacillus pantothenticus is triggered by high salinity and low growth temperature.
The quantification of the intracellular concentration of ectoine in Virgibacillus pantothenticus revealed that the production of this compatible solute is triggered either by an increase in the external salinity or by a reduction in the growth temperature. This finding reflects increased transcription of the ectoine biosynthetic operon (ectABC) under both environmental conditions.
