Astragalin from cassia alata induces dna adducts in vitro and repairable dna damage in the yeast saccharomyces cerevisiae
(2012) [Journal article]Reverse phase-solid phase extraction from Cassia alata leaves (CaRP) was used to obtain a refined extract. Higher than wild-type sensitivity to CaRP was exhibited by 16 haploid Saccharomyces cerevisiae mutants with defects ... -
Comparative genomics supports that brazilian bioethanol Saccharomyces cerevisiae comprise a unified group of domesticated strains related to cachaça spirit yeasts
(2021) [Journal article]Ethanol production from sugarcane is a key renewable fuel industry in Brazil. Major drivers of this alcoholic fermentation are Saccharomyces cerevisiae strains that originally were contaminants to the system and yet prevail ... -
Efeito de um composto de leveduras na incidência de diarreia em bezerras criadas em diferentes sistemas de alojamento
(2020) [Journal article]O objetivo do presente estudo foi avaliar o efeito da suplementação de um produto composto de cultura de levedura e levedura enzimaticamente hidrolisada na incidência de diarreia e no desenvol¬vimento corporal de bezerras ... -
Expression of the bacterial recA gene impairs genetic recombination and sporulation in a Saccharomyces cerevisae diploid strain
(2003) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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 ... -
Metabolic and ruminal fluid markers of dairy cows supplemented with a combination of yeast culture and hydrolyzed yeast
(2017) [Journal article]Background: In order to reduce the effects of a negative energy balance, some measures have been taken into account in nutritional management during the transition period. The use of yeast, has been a good alternative used ... -
Pharmacology and toxicology of diphenyl diselenide in several biological models
(2007) [Journal article]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) [Journal article]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 ... -
Saccharomyces cerevisiae, a pérola dourada da microbiologia
(2022) [Journal article] -
Transcriptional profiling of Saccharomyces cerevisiae exposed to propolis
(2012) [Journal article]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 ...
