Kinetics of Bioethanol Production from Lactose Converted by Kluyveromyces Marxianus
A kinetic model for ethanol fermentation of lactose using yeast Kluyveromyces marxianus DSMZ 5422 is proposed. The model consists of a set of differential equations which account for substrate consumption, ethanol production and biomass production. In the model, it is assumed that alcoholic fermentation is inhibited by ethanol itself and that a different metabolic pathway is set at certain etha...
متن کاملCharacterization of Yeast Protein Enzymatic Hydrolysis and Autolysis in Saccharomyces cerevisiae and Kluyveromyces marxianus
Protein recovery under sonication treatment and autolysis, also protein hydrolysis progress during enzymatic hydrolysis (using trypsin and chymotrypsin) and autolysis (using endogenous enzymes) were investigated in Saccharomyces cerevisiae and Kluyveromyces marxianus. Crude protein content of dried yeast cells were 53.22% and 45.6% for S.cerevisiae and K.marxianus, respectively. After 96 hrs of...
متن کاملHydrolysis of lactose by immobilized microorganisms.
Cells of Lactobacillus bulgaricus, Escherichia coli, and Kluyveromyces (Saccharomyces) lactis immobilized in polyacrylamide gel beads retained 27 to 61% of the beta-galactosidase activity of intact cells. Optimum temperature and pH and thermostability of these microbial beta-galactosidases were negligibly affected by the immobilization. Km values of beta-galactosidase in immobilized cells of L....
متن کاملNUTRIENT BALANCE AND METABOLIC ANALYSIS IN A Kluyveromyces marxianus FERMENTATION WITH LACTOSE-ADDED WHEY
Addition of lactose on whey to produce an alcoholic product by fermentation is optimized in order to maximise final ethanol concentrations and lactose consumption. The effect of the supplementation of the broth with yeast extract, ammonium sulphate, oxygen, protein, peptides and the vitamins nicotinic acid, biotin, pantothenic acid and inositol on aerobic cell growth was also studied. The Crabt...
