Resumo: Cell growth of Saccaromyces cerevisiae is often inhibited by acetic acid when it is associated with high levels of ethanol and other toxic metabolites which block fermentative metabolism by means of feedback mechanisms. Purslane (Portulaca oleracea L. var. sativa) is a green leafy vegetable, used widely in regional dishes, that has a high content and great diversity of biologically active phytochemicals. The fertilisation of purslane using NH4NO3 (60 kg/ha) was found to positively influence its production without negatively impacting its functional value. The simultaneous exposure of S. cerevisiae UE-ME3 to 25 mM acetic acid and 2% (v/v) purslane-leaf extract with high antioxidant activity, during 200 min, resulted in the maintenance of the biomass produced, cell viability, oxidative stress level, antioxidant enzyme activities ALP, GPx and CTA1 and cell damage levels approximate to those of the control group, as well as leading to an increase in GR and SOD1 antioxidant activities. Thus, ethanolic extract of purslane leaf seems to counteract the cell death signature induced by 25 mM acetic acid.
