21. Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production
Abstract : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. READ MORE

22. Fermentation of lignocellulosic material : a study on bacterial contamination and yeast physiology
Abstract : Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based upon this are classified as 1st generation and 2nd generation. READ MORE

23. Short-term adaptation of S. cerevisiae to lignocellulosic inhibitors: Underlying metabolic and physiological changes
Abstract : The limited tolerance of Saccharomyces cerevisiae (budding yeast) to inhibitors present in lignocellulosic hydrolysates is a major challenge in second-generation bioethanol production. Short-term adaptation of the yeast to lignocellulosic hydrolysates during cell propagation has been shown to improve its tolerance, and thus its performance in lignocellulose fermentation. READ MORE

24. Improving Ethanol Production from Lignocellulose Hydrolyzates: Fed-batch Fermentation, Yeast Cultivation and Strain Development for Increased Tolerance
Abstract : Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. READ MORE

25. Ethanol production by recombinant and natural xylose-utilising yeasts
Abstract : The xylose-fermenting capacity of recombinant Saccharomyces cerevisiae carrying XYL1 and XYL2 from Pichia stipitis, which encode xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, is poor due to high xylitol formation. Whereas, P. READ MORE
