Engineering a stable high-copy episomal plasmid in Yarrowia lipolytica.

Episomal plasmids are widely used in yeast metabolic engineering for their flexibility and high transformation efficiency. However, their application in Yarrowia lipolytica is often limited by low copy number and insufficient genetic stability. In this study, a robust episomal plasmid that balanced genetic stability an...

Palmitoleic Acid Enhances the Tolerance of Lager Yeast to Oxidation Stress by Regulating the Multilevel Defense System

Oxidative stress is a major physiological constraint on industrial lager yeast, compromising fermentation efficiency and flavor quality. Unsaturated fatty acids are known to influence membrane fluidity, but whether exogenous fatty acid supplementation can actively reprogram the yeast defense system, beyond serving as a...

O-glycosylation modification is crucial for the function of T9SS core component protein GldL in Cytophaga hutchinsonii.

This work provides the first evidence of GldL glycosylation and establishes its critical role in T9SS function, and offers a novel perspective for elucidating cellulose degradation in C. hutchinsonii.
