Expression of the bacterial recA gene impairs genetic recombination and sporulation in a Saccharomyces cerevisae diploid strain
(2003) [Artigo de periódico]The Escherichia coli RecA protein (RecAp) has been demonstrated to induce mutagenesis in yeast cells, although there is still little information on the role of the RecAp in yeast recombination events. We evaluated spontaneous ... -
Genotoxic effect of alkaloids
(1991) [Artigo de periódico]Because of the increased use of alkaloids in general medical practice in recent years, it is of interest to determine genotoxic, mutagenic and recombinogenic response to different groups of alkaloids in prokaryotic and ... -
Glutathione peroxidase induction protects Saccharomyces cerevisiae sod1deltasod2delta double mutants against oxidative damage
(2004) [Artigo de periódico]Saccharomyces cerevisiae mutants deficient in superoxide dismutase genes (sod1∆, sod2∆and the double mutant) were subjected to H2O2 stress in the stationary phase. The highest sensitivity was observed in the sod2∆mutant, ... -
High levels of catalase in SOD mutants of Saccharomyces cerevisae in high aeration conditions
(2005) [Artigo de periódico]Saccharomyces cerevisiae mutants deficient in superoxide dismutase genes (sod1Δ, sod2Δ and sod1Δsod2Δ mutants) in a stationary phase of growth under high aeration conditions were subjected to H2O2 stress. All the mutants ... -
Identification by PCR and evaluation of probiotic potential in yeast strains found in kefir samples in the city of Santa Maria, RS, Brazil
(2018) [Artigo de periódico]Kefir is a product elaborated from the symbiotic fermentation of different microorganisms. The Kluyveromyces and Saccharomyces genera are the major representatives of the yeasts found in kefir microbiota. The only pobiotic ... -
Influence of Brettanomyces custersianus upon the activity of Saccharomyces cerevisiae strains during the tumultuous phase of vinification
(2011) [Artigo de periódico]The aim of this work was to evaluate the influence of Brettanomyces custersianus on the metabolic activity of Saccharomyces cerevisiae during the tumultuous stage of wine production. The Cabernet Sauvignon grape must with ... -
Pharmacology and toxicology of diphenyl diselenide in several biological models
(2007) [Artigo de periódico]The pharmacology of synthetic organoselenium compounds indicates that they can be used as antioxidants, enzyme inhibitors, neuroprotectors, anti-tumor and anti-infectious agents, and immunomodulators. In this review, we ... -
Production of functional killer protein in batch cultures upon a shift from aerobic to anaerobic conditions
(2011) [Artigo de periódico]The aim of this work was to study the production of functional protein in yeast culture. The cells of Saccharomyces cerevisiae Embrapa 1B (K+R+) killed a strain of Saccharomyces cerevisiae Embrapa 26B (K-R-)in grape must ... -

Transcriptional profiling of Saccharomyces cerevisiae exposed to propolis
(2012) [Artigo de periódico]Background: Propolis is a natural product of plant resins collected by honeybees (Apis mellifera) from various plant sources. Our previous studies indicated that propolis sensitivity is dependent on the mitochondrial ...
