Response mechanisms of Saccharomyces cerevisiae to the stress factors present in lignocellulose hydrolysate and strategies for constructing robust strains

Biotechnology for Biofuels and Bioproducts, Journal Year: 2022, Volume and Issue: 15(1)

Published: March 15, 2022

Abstract Bioconversion of lignocellulosic biomass to biofuels such as bioethanol and high value-added products has attracted great interest in recent decades due the carbon neutral nature feedstock. However, there are still many key technical difficulties for industrial application bioconversion processes. One challenges associated with microorganism Saccharomyces cerevisiae that is usually used production refers inhibition yeast by various stress factors. These inhibitive effects seriously restrict growth fermentation performance strains, resulting reduced efficiency. Therefore, improving response ability strains significance bioethanol. In this article, mechanisms S. hydrolysate-derived factors including organic acids, furan aldehydes, phenolic compounds have been reviewed. Organic acids mainly stimulate cells induce intracellular acidification, aldehydes break redox balance, a greater effect on membrane homeostasis. damages lead inadequate energy supply dysregulation transcription translation processes, then activate series responses. The regulation these discussed regard cell wall/membrane, energy, amino transcriptional translational, regulation. reported target genes contribute improvement strain summarized. Furthermore, genetic engineering strategies constructing multilevel defense eliminating order provide robust construction. It recommended can be constructed intervention metabolic based specific Rational design gene control intensification enzymes good construction strains. Graphical
