Effects of culture conditions on ergosterol biosynthesis by Saccharomyces cerevisiae.
Ergosterol is an essential component of yeast cells that maintains the integrity of the membrane. It was investigated as an important factor in the ethanol tolerance of yeast cells. We investigated the effects of brewing conditions on the ergosterol contents of S. cerevisiae K-9, sake yeast, several kinds of Saccharomyces cerevisiae that produce more than 20% ethanol, and X2180-1A, laboratory y...
متن کاملRegulation of early enzymes of ergosterol biosynthesis in Saccharomyces cerevisiae.
In order to determine the regulation mechanisms of ergosterol biosynthesis in yeast, we developed growth conditions leading to high or limiting ergosterol levels in wild type and sterol-auxotrophic mutant strains. An excess of sterol is obtained in anaerobic sterol-supplemented cultures of mutant and wild type strains. A low sterol level is obtained in aerobic growth conditions in mutant strain...
متن کاملEffect of culture conditions on ergosterol as an indicator of biomass in the aquatic hyphomycetes.
Ergosterol is a membrane component specific to fungi that can be used to estimate fungal biomass using appropriate factors of conversion. Our objectives were to determine the limits of use of ergosterol content as a measure of biomass for aquatic hyphomycetes, and to evaluate a previously established ergosterol-to-biomass conversion factor. We varied inoculum quality, growth medium, and degree ...

15 صفحه اولInvestigation of Culture Conditions for Biosynthesis of Silver Nanoparticles Using Aspergillus fumigatus
In this study, silver nanoparticles were synthesized using the fungus, Aspergillus fumigatus. The effects of three independent variables including glucose content of culture media, initial pH and initial spore concentration on biosynthesis of silver nanoparticles were investigated. These variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...
