to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...

Introduction: The purpose of this study was formulation and preparation of a proper culture medium for Saccharomyces cerevisiae var. boulardii with molasses and animal serum. Methods: A fully-crossed factorial design contain 5%, 10% and 20% of molasses (M) with 0, 1% and 5% animal serum (S) was used in this study. The pH of all culture medias were adjusted to 5.6 with acetic acid. The seed was ...

background and purpose: by using advanced detection/identification methods, the list of emerging uncommon opportunistic yeast infections is rapidly expanding worldwide. our aim in the present study was sequence-based species delineation of previously unidentified yeasts obtained from a clinically yeast collection. materials and methods: a total of twenty three out of the 855 (5.7%) yeast isolat...

The study was conducted in Completely Randomized Design with eight treatments replicated three times. were T1 (Indian olive 500 g +250 ml water +150 sugar), T2 +200 T3 T4 +300 T5 sugar +1.5 yeast), T6 T7 yeast) and T8 yeast). Total soluble solids, pH specific gravity decreased while alcohol content, acidity sensory qualities increased increasing length of fermentation. From the above experiment...

Yeast switches for glucose and galactose Some organisms can switch metabolic pathways depending on their environment. One such example is yeast, which transition between the sugars as carbon sources. Boocock et al. show that this ability has undergone selection, resulting in maintenance of two incompatible a select set yeast strains within single species. A phylogenetic analysis supports these ...

Background: Enhancing the industrial yeast strains ethyl acetate yield through a precise and seamless genetic manipulation strategy without any extraneous DNA sequences is an essential requisite and significant demand. Objectives: For increasing the ethyl acetate yield of industrial brewer’s yeast strain, all the ATF1 alleles were overexpressed t...

The influence of two yeast strains and the addition copper sulphate on aroma Riesling wines was monitored. Two commercially available strains, Zymaflore VL3 X-Pure, were applied. General composition, volatile thiols, norisoprenoids, free terpenes, fermentation, sulphur compounds content determined, sensory attributes assessed by 22 tasters in a balanced incomplete block design (BIBD). produced ...

 Abstract Background: The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast spec...
