Biotechnological properties of distillery and laboratory yeasts in response to industrial stresses

摘要: The stress sensitivity of different wild-type strains was evaluated, as well the response cells arrested at cell cycle positions to high hydrostatic pressure (HPP). HHP chosen both for its importance in food decontamination and assessment suitability a model general understanding yeast response. Studies were conducted with four industrial laboratory (two haploid two diploid) that differed their backgrounds. Fundamental differences found between populations. Industrial clearly more sensitive ethanol stresses than strains. However, production higher Furthermore, no correlation observed ploidy resistance. Yeast G1 phase led an enhancement tolerance compared unarrested, G2 arrested, S cells. Moreover, phase. Again, responses yeasts correlated concentration temperature stress, which suggests it would be useful stress.
