Article Synopsis
- Kluyveromyces marxianus, a yeast strain, shows promise for producing yeast extracts due to its effective fermentation and nutritional features.
- The study investigates the process of yeast autolysis, which is critical for extract production, and reveals that vacuum negative pressure and higher temperatures trigger this breakdown, but the molecular mechanisms are not yet fully understood.
- RNA-seq analysis identified numerous differentially expressed genes related to RNA synthesis and protein translation during autolysis, indicating that stress leads to cell damage through activated pathways like ERAD and autophagy, ultimately contributing to yeast cell autolysis.
Yeast autolysis refers to the process in which cells degrade and release intracellular contents under specific conditions by endogenous enzymes such as proteases, nucleases and lipid enzymes. Protein-rich baker's yeast is widely used to produce yeast extract in food industry, however, the molecular mechanism related to baker's yeast autolysis is still unclear. In this study, RNA-seq technology and biochemical analysis were performed to analyze the autolysis processes in baker's yeast.
