A Single-Nucleotide Insertion in a Drug Transporter Gene Induces a Thermotolerance Phenotype in Gluconobacter frateurii by Increasing the NADPH/NADP+ Ratio via Metabolic Change.

Abstract excerpt

Thermotolerant microorganisms are beneficial to the fermentation industry because they reduce the need for cooling and offer other operational advantages. Previously, we obtained a thermally adapted Gluconobacter frateurii strain by experimental evolution. In the present study, we found only a single G insertion in the adapted strain, which causes a frameshift in a gene encoding a putative drug transporter. A...
