Kinetics of lactose fermentation using a recombinant Saccharomyces cerevisiae strain.
This work presents a multi-route, non-structural kinetic model for interpretation of ethanol fermentation of lactose using a recombinant flocculent Saccharomyces cerevisiae strain expressing both the LAC4 (coding for beta-galactosidase) and LAC12 (coding for lactose permease) genes of Kluyveromyces lactis. In this model, the values of different metabolic pathways are calculated applying a modif...
متن کاملContinuous ethanol fermentation of lactose by a recombinant flocculating Saccharomyces cerevisiae strain.
Alcohol fermentation of lactose was investigated using a recombinant flocculating Saccharomyces cerevisiae, expressing the LAC4 (coding for beta-galactosidase) and LAC12 (coding for lactose permease) genes of Kluyveromyces marxianus. Data on yeast fermentation and growth on a medium containing lactose as the sole carbon source are presented. In the range of studied lactose concentrations, total...
متن کاملMetabolic engineering of Saccharomyces cerevisiae for lactose/whey fermentation.
Lactose is an interesting carbon source for the production of several bio-products by fermentation, primarily because it is the major component of cheese whey, the main by-product of dairy activities. However, the microorganism more widely used in industrial fermentation processes, the yeast Saccharomyces cerevisiae, does not have a lactose metabolization system. Therefore, several metabolic en...
متن کاملKinetics of D-lactic acid production by Sporolactobacillus sp. strain CASD using repeated batch fermentation.
D-lactic acid was produced by Sporolactobacillus sp. strain CASD in repeated batch fermentation with one- and two-reactor systems. The strain showed relatively high energy consumption in its growth-related metabolism in comparison with other lactic acid producers. When the fermentation was repeated with 10% (v/v) of previous culture to start a new batch, D-lactic acid production shifted from be...
متن کاملOptimization of enterokinase fermentation using a recombinant Saccharomyces cerevisiae
The optimization of enterokinase fermentation was performed with a recombinant Saccharomyces cerevisiae. The maximum enterokinase yield and specific yield were obtained when the ratio of yeast extract to bacto peptone was 5:5. However, the fraction of plasmid-containing cells was approximately 65% for most nitrogen source ratios. From batch cultures, the minimum DOT level was found to be a key ...
