Secretory expression of cyclohexanone monooxygenase by methylotrophic yeast for efficient omeprazole sulfide bio-oxidation

open access: yesBioresources and Bioprocessing, 2021
Prochiral pyrmetazole can be asymmetrically oxidized into (S)-omeprazole, a proton pump inhibitor that is used to treat gastroesophageal reflux, by an engineered cyclohexanone monooxygenase (CHMO Acineto -Mut) that has high stereoselectivity.

Effects of cadmium sulfide nanoparticles on sulfate bioreduction and oxidative stress in Desulfovibrio desulfuricans

open access: yesBioresources and Bioprocessing, 2022
Highlight Efficiency of bioreduction of sulfate and biomass can be increased by CdS NPs. It is important for the EPS of RSB to improve the sulfate reduction efficiency. Utilization efficiency of extracellular electrons by RSB can be enhanced through EPS.

Two strategies to improve the supply of PKS extender units for ansamitocin P-3 biosynthesis by CRISPR–Cas9

open access: yesBioresources and Bioprocessing, 2022
Ansamitocin P-3 (AP-3) produced by Actinosynnema pretiosum is a potent antitumor agent. However, lack of efficient genome editing tools greatly hinders the AP-3 overproduction in A. pretiosum.
