The effect of ultraviolet light on living yeast cells.

The effect of incoherent ultraviolet light on the renal capsule tissue using dynamic mechanical analysis and FTIR spectroscopy

Photoinactivation and photoreactivation of constitutive and adaptive respiratory systems of Azotobacter.

Acetate grown cells of Azotobacter, like sucrose grown cells (Stone and Wilson, 1952), are unadapted to the oxidation of succinic acid although possessing an enzyme system capable of oxidizing succinate. Hence the adaptation of these cells to succinic acid may be termed a functional change in the physiology of the organism. In contrast, glucose grown cells of Saccharomyces cerevisae are unadapt...

Effect of dietary supplementation with zinc enriched yeast (Saccharomyces cerevisiae) on immunity of rainbow trout (Oncorhynchus mykiss)

Zinc (Zn) is an essential trace element in all living organisms, and the first eukaryotic Zn uptake transporter was discovered in the yeast, Saccharomyces cerevisiae. Zinc-enriched yeast is a currently available Zn supplement. The purpose of the investigation was to compare and evaluate the effect of Zn enriched yeast in rainbow trout. The fish (mean body weight 10 ± 0.5 g) were fed a commercia...

Respiratory mutant and liquid holding recovery inhibition in yeast cells

Background: Cell ability to recover from radiation damage is of great relevance in cancer treatment. It is often believed that the inhibition of cell ability to the liquid holding recovery (LHR) may be an indicator of the overall suppression of cell ability to recover from potentially lethal radiation damage. However, the literature contains no experimental evidence whether the LHR inhibition m...

New type of ultraviolet light-sensitive mutation in yeast.

Four temperature-sensitive ultraviolet light-sensitive mutants of yeast have been isolated. All four mutations show complementation in diploid cells and the phenotypes associated with the rad (ts) mutations are the result of the activities of single mendelian genes.
