N2 - Methylotrophic yeast Komagataella phaffii is widely used in biotechnology for recombinant protein production. Due to the practical significance of these yeasts, it is extremely important to properly select cultivation conditions and optimize the media composition. In this study the effect of biotin starvation on gene expression in K. phaffii at transcriptome level was investigated. It was demonstrated, that the response of K. phaffii cell to biotin deficiency strongly depends on the carbon source in the medium.
