The aw of saturated trehalose solutions at 20, 25, 30, 35 and 40 1C was also determined and found to be between 0.953 and 0.928. These values agreed well with predictions made using aw data for trehalose solutions calculated at the solubility concentration at the various temperatures. r 2007 Swiss Society of Food Science and Technology.
(PDF) Lack of correlation between trehalose accumulation Lack of correlation between trehalose accumulation, cell viability and intracellular acidification as induced by various stresses in Saccharomyces cerevisiae May 1998 Microbiology 144 ( Pt 4)(4
The intracellular trehalose delivery efficiency was optimized by manipulating the side chain length, degree of substitution, and concentration of the pseudopeptides with different hydrophobic alkyl side chains, the pH, temperature, and time of incubation, as well as the polymer-to-cell ratio and the concentration of extracellular trehalose.
Correlation of Intracellular Trehalose Concentration with FIG 5 Intracellular concentrations of trehalose in 10 soil E. coli strains (designated with an S), four E. coli isolates from municipal wastewater (designated by WW), and the lab strain MG1655 under the desiccation condition (solid bars) or the hydrated condition (open bars). - "Correlation of Intracellular Trehalose Concentration with Desiccation Resistance of Soil Escherichia coli Populations"
Correlation of intracellular trehalose concentration with All E. coli strains produced more intracellular trehalose, proline, and glutamine under the desiccation condition than the hydrated control, and only the trehalose concentration exhibited a significant correlation with the desiccation-contributed die-off coefficients (Spearman's =-1.0; P = 0.02).
Jun 26, 2015 · Once in the cell, intracellular esterases hydrolyzed the 6-O-Ac-Tre molecules, releasing free trehalose into the cytoplasm. The total concentration of intracellular trehalose (plus acetylated variants) reached as high as 10 fold the extracellular concentration of 6-O-Ac-Tre, attaining concentrations suitable for applications in biopreservation.
Influence of intracellular trehalose concentration and pre Aug 01, 2011 · Cellular cryosurvival increased approximately linearly with pre-freeze cell volume up to the normal volume of fresh cells; diminished cell survival correlated with subnormal pre-freeze cell volume in some cases even at >100 mM intracellular trehalose concentration.
MAL62 overeion enhances uridine diphosphoglucose Oct 19, 2020 · Moreover, in strains lacking trehalose synthesis, the cell viability in the late phase of prefermentation freezing coupled with MAL62 overeion was slightly reduced, which can be explained by the increase in the intracellular glycerol concentration. This result was consistent with the elevated transcription of glycerol synthesis pathway
Sep 30, 2016 · This correlation between desiccation tolerance of the microorganism and its ability to protect some plants from drought seems to depend on the microorganisms capacity to finely regulate the concentration of trehalose in the plant as a signal of drying damage, since trehalose triggers the plant-defense system to counteract the damage caused by drought.(PDF) Correlation of Intracellular Trehalose Concentration All E. coli strains produced more intracellular trehalose, proline, and glutamine under the desiccation condition than the hydrated control, and only the trehalose concentration exhibited a
