To monitor eukaryotic mRNA metabolism, we developed comparative dynamic transcriptome analysis (cDTA). cDTA provides absolute rates of mRNA synthesis and decay in Saccharomyces cerevisiae (Sc) cells with the use of Schizosaccharomyces pombe (Sp) as an internal standard. cDTA uses nonperturbing metabolic labeling that supersedes conventional methods for mRNA turnover analysis. cDTA reveals that ...
The demand for ethanol in Brazil is growing. However, although the country one of largest producers this fuel, it still necessary to diversify production matrix. In that regard, studies with different raw materials are needed, mainly use low cost and high available wastes such as lignocellulosic residues from agriculture. Therefore, study aimed analyze bioethanol corn stover. An alkaline pretre...
Background: Birds are considered as a reservoir for pathogenic and non-pathogenic fungi. Pigeon droppings have the potential for spreading these fungi to the environment. Cryptococcus species are important fungi associated with pigeon droppings. In this regard, there are many types of yeast associated with guano that is important for human and animal health. Ai...
several strains of saccharomyces cerevisiae were isolated from different sources. these strains were under taken for ethanol tolerance analysis and growth under stress condition. exponential phase to various concentrations of ethanol (2–26% v/v) for 1 h was used for isolation of resistant strains. viable cells were isolated and purified by inoculation of diluted samples on yeast extract peptone...
background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
Regulation of the levels of the five enzymes required for the biosynthesis of isoleucine and valine was studied in a Saccharomyces sp. When a mixture of isoleucine, valine, and leucine was added to the medium, the enzymes in the wild-type strain were repressed from about 30% (transaminase B) to about 90% (acetohydroxy acid synthetase) relative to the level in minimal medium-grown cells. Repress...
Four sourdoughs (A to D) were produced under practical conditions, using a starter obtained from a mixture of three commercially available sourdough starters and baker's yeast. The doughs were continuously propagated until the composition of the microbiota remained stable. A fungi-specific PCR-denaturing gradient gel electrophoresis (DGGE) system was established to monitor the development of th...
The temperature range of growth was 5-39.5 C. Candida krusei was able to grow at 46 C. Torulopsis albida was able to grow at 0 C. The sugar tolerance was 50-55O Brix syrup. Saccharomyces ro8ei and Torulopsis lactis-condensi were able to tolerate 600 Brix syrup. Attractivity tests with dried-fruit beetles indicated that they responded most to Candida krusei, then Hanseniaspora valbyensis, fig ti...
A gene fusion between the Saccharomyces cerevisiae actin gene promoter and the cDNA of the Fusarium solani f. sp. pisi pelA gene has been constructed. This expression cassette has been introduced into the industrial wine yeast strain T73. The resulting recombinant strain is able to secrete active PELA enzyme into the culture medium. In preliminary microvinification experiments the wine produced...
