2019/6/6/ · The fermentation performance for SS120 is not yet comparable to the GS1.11-26 strain. To develop strains with superior fermentation performance in terms of d-xylose consumption and ethanol production rates, expression of d-xylose metabolism genes must first be optimized. Selection of a promoter to drive expression of a foreign gene is also
2017/11/1/ · Introduction. The aerobic microorganisms used in industrial fermentation processes generally demand a large quantity of oxygen in order to re-oxidize nicotinamide adenine dinucleotide phosphate (NADPH) and/or flavin adenine dinucleotide (FADH) to generate metabolic adenosine triphosphate (ATP) along with by-product synthesis (Huang
