Glycerol is one of the few carbon sources that can be utilized by Mycoplasma pneumoniae. Glycerol metabolism involves uptake by facilitated diffusion, phosphorylation, and the oxidation of glycerol 3-phosphate to dihydroxyacetone phosphate, a glycolytic intermediate. We have analyzed the expression of the genes involved in glycerol metabolism and observed constitutive expression irrespective of...

The emergence of biological phosphate esters glycerol could have been a crucial step in the origin and evolution life on early Earth as phosphates today play central role biochemistry. We investigate here formation by employing various rock samples, salts, minerals potential catalysts to aid phosphorylation process. report synthesis including glycerol-1-phosphate, glycerol-2-phosphate, cyclic g...

to determine the effect of different levels of l-glutamine and glycerol on freezing coated sperm, semen were collected from 4 taleshi rams through artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. ejaculates were pooled, centrifuged and supernatant was removed, then cell fractions were used. samples were split into 9 equal parts and 3 (g3), 5 (g5) or 7% (g7) glycerol ...

cell lines derived from mammalian are dominant systems for the production of recombinant therapeutic proteins because of their capacity for correct protein folding, assembly and post-translational modification. in the search of an efficient method for the production of  a recombinant protein using animal cell culture, we investigated the effects of different treatment including fetal calf serum...

the effect of different carbon sources on bacterial cellulose production by gluconacetobacter xylinus (ptcc 1734) and two newly isolated strains (from vinegar) under static culture conditions was studied. the production of bacterial cellulose was examined in modified hestrin-shramm medium by replacing d-glucose with other carbon sources. the results showed that the yield and characteristics of ...

Conversion of glycerol from biodiesel production to glycerol carbonate was studied by esterification with dimethyl carbonate in a non-catalytic supercritical condition. It was found that in a non-catalytic supercritical condition, glycerol at higher purity gave higher yield of glycerol carbonate at 98 wt% after reaction at 300 °C/20-40 MPa/15 min. The yield of glycerol carbonate was observed to...
