Ibai Lenitz joined the Industrial Biotechnology Division as a PhD student in September 2019. His research focuses on understanding the regulation of study of tolerance-related genes in yeast for plant biomass conversion. The selected genes contribute to robustness against inhibitors found in lignocellulosic hydrolysates. In this project, the cutting-edge CRISPRi technology is used in order to modulate gene expression. CRISPRi technology allows one to regulate the expression genes in a reversible manner, without any sort of alterations to the sequence, which makes it a great tool for fine-tuning of gene expression levels. The obtained knowledge in this research will lead to a better understanding of how yeast responds to inhibitor-related stress and also contribute towards achieving a more efficient lignocellulose-based bioprocesses.
