Background For many years, bakers have been considered a professional group at risk of developing allergic diseases by factors related to the work environment. In our country, in this employment sector, the frequency of allergic sensitization to dust mites, wheat flour, soy and yeast is not known. This study aimed at assessing the frequency of work-related symptoms and sensitivity to mites and ...

In this study, the feasibility of cruxrhodopsin (CR) production as a multifunctional nanoparticle was investigated and optimized by Halorculasp. IRU1, a novel halophile Archaea isolated from Urmia Lake, Iran in batch experiments. In this case, Taguchi method was used for effect measurement of three important factors (petrochemical wastewater, yeast extract and KH2PO4) on CR production. Results ...

Catalase from bakers’ yeast has been purified to homogeneity in the analytical ultracentrifuge and in gel electrophoresis; sedimentation measurements permit an estimation of its molecular weight as 248,000. Under denaturing conditions, polyacrylamide gel electrophoresis revealed dissociation of a major component of molecular weight 61,000, which constituted 90% of the total protein of the stain...

15N NMR spectra were taken of 15N-enriched tRNA extracted from bakers yeast; ammonium sulfate was used as a nitrogen source. The increase in the degree of denaturation of tRNA, which occurs with increase in temperature from 30 degrees C to 70 degrees C, resulted in no large changes in 15N chemical shifts at acidic and neutral pH but quite pronounced changes in proton-15N nuclear Overhauser effe...

The complete amino acid sequence of chicken heart cytochrome c has been established. This primary structure is typically that of a “mammalian-type” cytochrome c showing the characteristic groupings of hydrophobic and basic residues, and, like the other cytochromes c from vertebrate species, has an acetylated amino-terminal residue. Chicken heart cytochrome c differs from the horse, beef, human,...
