    S.cerevisiae is an industrially important organism known for its ability to produce ethanol as the demand for ethanol is increasing day by day all over the world, the need to find better and alternative ways to increase ethanol production is also rising. In this work we have proposed such alternative but effective method for producing ethanol by S.cerevisiae. Here, we are reporting for the first time the effect of nitrosative stress on ethanol production. Under in vivo condition, nitrosative stress is marked by the modification of macromolecules in the presence of reactive nitrogen species (RNS). Our result showed that treated cells were more capable for ethanol production compared with untreated cells. Our result also showed enhanced alcohol dehydrogenase activity under stressed condition. Further ethanol production was also optimized by using Response Surface Methodology (RSM) with stressed cells. Further, production of ethanol with immobilized beads of stress affected Saccharomyces cerevisiae was also determined. Overall, the obtained data showed that under nitrosative stress, the maximum ethanol production is 34.4 g/l after 24 h and such higher production was observed even after several cycles of fermentation. This is the first report of this kind showing the relation between nitrosative stress and ethanol production in Saccharomyces cerevisiae which may have important industrial application.

    Abstract Aims The work aimed to understand the important changes during glucose metabolism in Saccharomyces cerevisiae under acidified sodium nitrite (ac.NaNO2) mediated nitrosative stress. Methods and Results Confocal microscopy and fluorescence-activated cell sorting analysis were performed to investigate the generation of reactive nitrogen and oxygen species, and redox homeostasis under nitrosative stress was also characterized. Quantitative PCR analysis revealed that the expression of ADH genes was upregulated under such condition, whereas the ACO2 gene was downregulated. Some of the enzymes of the tricarboxylic acid cycle were partially inhibited, whereas malate metabolism and alcoholic fermentation were increased under nitrosative stress. Kinetics of ethanol production was also characterized. A network analysis was conducted to validate our findings. In the presence of ac.NaNO2, in vitro protein tyrosine nitration formation was checked by western blotting using pure alcohol dehydrogenase and aconitase. Conclusions Alcoholic fermentation rate was increased under stress condition and this altered metabolism might be conjoined with the defence machinery to overcome the nitrosative stress. Significance and Impact of the Study This is the first work of this kind where the role of metabolism under nitrosative stress has been characterized in S. cerevisiae and it will provide a base to develop an alternative method of industrial ethanol production.
