Resumen de: US20260327661A1
Disclosed are systems and methods for producing renewable alcohols by fermentative processes using selected promoters that differentially regulate the expression of genes encoding fermentation enzymes during the propagation and production phases of the fermentative processes. These systems and methods are able to increase production efficiency and yield in the conversion of sugars to renewable alcohols by fermentation in microbes. This is accomplished by the use of novel nucleic acid sequences that act as genetic switches to differentially control gene expression based on extra cellular stress; namely, stresses relating to fermentation processes. These sequences present a novel method for controlling endogenous gene expression without the need for the addition of heterlogous chemicals or signaling molecules.
