Cadmium (Cd) is a highly toxic pollutant and nonessential element for plant growth. Here, we investigated the levels of malondialdehyde (MDA), H2O2, sugars, activity gene expression antioxidant enzymes sugar metabolism-related in mycelia Pleurotus eryngii grown presence 0, 0.5, 1, 1.5, 2.0, 4.0 mg·L−1 Cd. Raising Cd concentration resulted increases, followed by decreases (MDA) H2O2 mycelia. The...

1. Certain sugars were transported across the buccal mucosa by a carrier-mediated mechanism. 2. The metabolic loss of sugars from the mouth in a 5 min test period was negligible. 3. The buccal mucosal transport process was stereospecific for D-glucose and L-arabinose. 4. The absorption of D-glucose, galactose and 3-O-methyl-D-glucose was at least partly dependent on the presence of sodium ions ...

The stop flow technique was used to investigate the permeability characteristics of the dog nephron to various C(14)-labeled non-electrolytes. 12 minutes after clamping the ureter, creatinine, PAH, and C(14) compound were injected intravenously. 2 minutes later, urine samples were collected. Urea and glycerol were able to enter the tubular urine along the entire nephron at rates which were comm...

Two polysaccharides (APS-I and APS-II) were isolated from the water extract of Radix Astragali and purified through ethanol precipitation, deproteination and by ion-exchange and gel-filtration chromatography. Their molecular weight was determined using high performance liquid chromatography and gel permeation chromatography (HPLC-GPC) and their monosaccharide composition was analyzed by TLC and...

We report development of a method for the direct measurement of the interaction between the N-terminal arm and the remainder of the dimerization domain in the Escherichia coli AraC protein, the regulator of the l-arabinose operon. The interaction was measured using surface plasmon resonance to monitor the association between the immobilized peptide arm and the dimerization domain, truncated of ...

A nonspecific cellobiose phosphorylase from Clostridium thermocellum, which has been purified over loo-fold, is active on 10 different glucosyl acceptors, D-glucose, Z-deoxyglucose, 6-deoxyglucose, D-glucosamine, D-mannose, D-a&rose, L-galactose, L-fucose, D-arabinose, and D-xylose. Following electrophoresis on polyacrylamide gels, the activity with various acceptors occurs at the location of t...

Sugar beet pulp (SBP) is a major byproduct from the sugar industries and consists of >20% w/w arabinose. The current work evaluated potential Enterobacter ludwigii assimilating pure arabinose rich hydrolysate SBP pellets for 2,3-butanediol (BDO) production. was obtained through dilute acid pretreatment (DAP) with sulphuric acid. process optimized solid loading to obtain free furan derivatives. ...
