Sugar uptake systems in Neurospora crassa are catabolically repressed by glucose. Synthesis of a low K(m) glucose uptake system (system II) in Neurospora is derepressed during starvation for an externally supplied source of carbon and energy. Fasting also results in the derepression of uptake systems for fructose, galactose, and lactose. In contrast to the repression observed when cells were gr...

The effects of cortisone on the dietary induction and repression of serine dehydrase, ornithine transaminase, and tyrosine transaminase were studied. In rats pretreated with cortisone dietary induction was affected relatively little, but carbohydrate repression was largely eliminated. The effects of cortisone and phenobarbital on the dietary induction of serine dehydrase and ornithine transamin...

Several compounds containing reduced nitrogen markedly increased the yields of cell-division compounds extractable from an A6 Vinca rosea L. crown gall tumor tissue. Casein hydrolysate, several amino acids, and ammonium salts were effective. Both trans-zeatin and ribosyl-trans-zeatin were substantially increased in total amount per culture and in concentration. These two compounds have been ide...

Studies by Christensen et wl. (1, 2) and by -4llison and associates (3) have demonstrated that the urinary excretion of peptides is greater than the urinary excretion of free amino acids following the infusion of partial hydrolysates of casein or of fibrin. Christensen and coworkers have shown also that infusion of these hydrolysates results in a greater persistence of peptides in the plasma th...

Expectation for renewable energy is increasing due to environmental pollution such as fossil fuel depletion, CO2 emission, and harmful gases. Therefore, in this study, extracted sugars of microalgae, which cause algal blooms crude glycerol, a biodiesel industry byproduct, were used simultaneously produce 2,3-BDO. The 2,3-BDO production using only was about 4.8 g/L at 18 h, the both sugar glycer...
