Production of Ethanol from Rice Straw using Xylose Fermenting Yeast Isolates
Abstract: With increasing energy demand world-over, there is a need to develop cost effective technologies for the production of bio fuels using renewable sources such as lignocellulosic biomass. However, ethanol productivity is still low and the process is not economically viable. The major limiting factors include the complex and highly crystalline structure of lignocellulosics, low loading rate during saccharification and low amount of hexose and pentose sugars generated during saccharification. Distiller’s …

Ethanol Production by Xylose Fermenting Yeast Cultures Using a Mixture of Dextrose and Xylose
Abstract: Ever-increasing demand for motor fuels has led to the search for alternate sources of energy world over. Lignocellulosic biomass is the most abundant, renewable source which is being replenished through photosynthesis. In many developed countries, a number of “Biorefineries” have been set up to produce ethanol from plant biomass. However, ethanol productivities are still low. Moreover, distiller’s ethanologenic yeast Saccharomyces cerevisiae cannot utilize pentoses, with the result that about 30% …

Enhanced Biodiesel Production Via Encapsulation of Yeast Cells in Biocompatible Polymers
Abstract: Yeast-based biodiesel production offers a sustainable alternative to conventional fossil fuels. However, factors like harsh environmental conditions and shear stress during processing can limit yeast cell viability and overall biodiesel yield. This study explores the potential of encapsulation technology using biocompatible polymers to improve yeast performance in biodiesel production. Encapsulation can create a protective barrier for yeast cells, shielding them from harsh environments and shear stress during processing. This protection …

Saccharomyces Cerevisiae and Pichia Pastoris Optimize NH4NO3 by 50 % in Solanum Lycopersicum Preventing N2O Release.
Abstract: In agriculture, the unregulated application of NH4NO3 for healthy growth of Solanum lycopersicum is associated in the soil with the denitrification of free NO3- (nitrate), with an increase in N2O, a greenhouse gas, that contributes to global warming, loss of soil fertility. An ecological option to avoid denitrification that releases N2O as other environmental problems is to inoculate S. lycopersicum seeds with endophytic yeasts that promote plant growth, such as …
