Some yeasts enzymatically decarboxylate pyruvate, releasing CO2, and acetaldehyde is subsequently reduced by NADH to form ethanol. The fermentation process generates only a net of 2 moles of ATP per mole of glucose. Other compounds that may be produced fermentatively are alcohols such as butanol,...
EthanolproductionFermentationGlucoseResourceefficiencyXyloseFermentation performance of these biomass hydrolysates is limited by the lack of industrially suitable organisms to convert both glucose and xylose efficiently. To resolve this issue, several methods have been suggested, e.g., co‐cultivation of two...
In the production of 2nd generation ethanol, using Saccharomyces cerevisiae, the highest productivity obtained using C5/C6 fermenting yeast is in the co-fermentation phase, in which xylose and glucose are fermented simultaneously. Extending this phase in a fed-batch process increases the yield, rate...
Analysis of strain performance in semi-aerobic batch culture The strain isolated from continuous culture after 100 generations was designated as strain D5A+H and was grown in batch culture on either xylose or glucose to assess its ability to utilise these carbon sources in the presence of pretreatm...
Beach-cast seaweed has recently garnered attention for its nutrient-rich composition, including proteins, carbohydrates, vitamins, minerals, and phytochemicals. This study focuses on the phenolic content and antioxidant potential of five Australian beach

]. The bioprocesses where yeasts convert glucose to ethanol are known as the glycolytic pathway followed by ethanol fermentation [35]. Fermentation (viz. the “anaerobic”-type transformation of glucose into ethanol) may occur despite the presence of O2 in the culture medium in significant ...
Briefly, 0.33 g of ADY was added to 5.0 mL of Yeast Extract Peptone Dextrose (YEPD) medium (20.0 g/L of glucose, 20.0 g/L of peptone, 10.0 g/L yeast extract), pre-warmed at 37 °C, left static for 30 min and then gently stirred. Thereafter, 3.8 mL of this yeast suspension was...
