Evaluating crude whey for bioethanol production using non-Saccharomyces yeast, Kluyveromyces marxianus

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...

Characterization 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...

Ethanol fermentation of sugar beet thick juice diluted with crude cheese whey by the flex yeast Kluyveromyces marxianus KD-15

Studies on the Optimiization of Biomass Production Using Kluyveromyces Marxianus Isolated from Paneer Whey

In the present study Kluyveromyces marxianus isolated from paneer whey was employed for biomass production. Various parameters like pH, temperature and nitrogen source were optimized for maximum biomass yield. The biomass yield was studied to vary with different nitrogen sources, pH and temperature. Ammonium sulphate, ammonium nitrate, beef extract and yeast extract were used as nitrogen source...

Production of inulinase from Kluyveromyces marxianus using dahlia tuber extract

Various carbon sources were evaluated for production of inulinase by yeast, Kluyveromyces marxianus MTCC 3995. Highest inulinase activity was observed with Dahlia extract (25.3 nkat mL(-1)) as carbon source. The enzyme activity was 1.4 folds higher than that observed in media containing pure chicory inulin (17.8 nkat mL(-1)). The yeast showed good growth on a simple medium containing dahlia ext...
