Succinic Acid Production With -Influence of an Electric Potential on the Intercellular NADH/NAD Balance.

Bioelectrochemical systems (BESs) offer a sustainable method for chemical production, including the enhanced production of succinic acid. By combining fermentation with BES, it could be possible to achieve sustainable succinic acid production and CO fixation using . In literature, the potential application of BES is commonly associated with increased succinate yields, as it is expected to enhance the availability of NADH, thereby influencing the intracellular nicotinamide adenine dinucleotide (NADH/NAD) balance.

Brewers' spent grain as carbon source for itaconate production with engineered Ustilago maydis.

Brewers' spent grain (BSG) is produced worldwide in millions of tons during the beer brewing process. Due to its high content of structural carbohydrates, BSG is a promising material for being valorised in biorefineries. In this study three process routes for producing itaconate from BSG hydrolysates are presented using the previously engineered smut fungi UstilagomaydisMB215Δcyp3ΔP::P as whole-cell biocatalyst.
