TL;DR: A hypothesis regarding the level of the ATP-ADP pool as a regulating mechanism for the glycolytic flux and product formation in L. lactis is discussed and inhibition of alcohol dehydrogenase might be partially responsible for the homolactic behavior of resting cells.

TL;DR: Enhanced xylose consumption was furthermore observed when the GXF1-strain was assessed in simultaneous saccharification and co-fermentation of pretreated wheat straw, however, the ethanol yield remained unchanged due to increased by-product formation.

TL;DR: The growth and production of lactic acid by two of three L. lactis strains in a two-phase system with 5.5% EO-PO and HPS100 were reduced by less than 10% compared with a reference fermentation in a normal growth medium, and when cell density reached the stationary phase in the first extractive fermentation, the lactate production was maintained.

TL;DR: In this article, an ethanol producing microbial strain, such as Saccharomyces cerevisiae strain, being able to grow and produce ethanol from lignocellulosic hydrolysates comprising growth inhibiting compounds of the group furfural and 5- hydroxy-methyl fur fural, in a batch, fed-batch or continuous fermentation, said microbial strain being tolerant to such inhibiting compound, which strain is upregulated and/or over expressed with regard to one or more of the following genes.
