Enhancing Bioethanol Productivity from Sugarcane Molasses by Saccharomyces cerevisiae Y17 KP096551

Abstract

is capable of producing approximately 106kg of sugar and 46kg of molasses. A typical molasses to ethanol conversion rate is 4kg of molasses/L ethanol (Lavarack, 2001). However, this rate can vary based on production practices and sugar content of the molasses (Nguyen et al., 2009 andSilalertruksa &Gheewala, 2010).Molasses composition is usually influenced by the variety and maturity of the cane and beet, soil, climate and the processing conditions in the factory (El-Gendy et al., 2013). High yielding and efficient fermentation of molasses with varying composition requires selection of special yeast strains having high tolerances to inhibitory conditions as well as ability of fast fermentation. Other natural requirements like tolerance to high alcohol, sugar and temperature are also necessary (Bazmi et al., 2007

Dynamic consolidated bioprocessing for innovative lab-scale production of bacterial alkaline phosphatase from Bacillus paralicheniformis strain APSO

“…Additionally, industrial sugar production from beets and sugarcane generates molasses, an opaque, nutrient-rich liquid, as a byproduct, thus providing a renewable, reliable, readily available, and low-cost raw material that can be used to feed most microorganisms, as it contains carbon, nitrogen, phosphorus, sodium, potassium, and magnesium. A concentrated sugar substrate such as molasses can be used to obtain a high yield of bio-based products via industrial-scale fermentation 6 .…”

Assessment of Fuel Properties Produced From Tamarix nilotica and Pluchea dioscoridis Plants

“…1). Several investigators reported that, crops contain free sugars make them more cost-effective feedstocks in bioethanol industry (Ensinas et al, 2009;Dhaliwal et al, 2011;Rasmey et al, 2018). Furthermore, the cellulose content recorded in T. nilotica (25.02%) was greater twofold than that of P. dioscoridis (10.04%) ( Fig.…”

Glycerol production by the UV-mutant marine yeast Wickerhamomyces anomalus HH16-MU15 via simultaneous saccharification and fermentation of fruit peels

“…According to [26], steam explosion and liquid hot water pretreatments of fruit peels can generate soluble inhibitors which hamper the cellulase enzymatic activity and hence the released reducing sugars. Toxic and inhibitory compounds vary with the pretreatment method and the waste type that might include soluble sugars, organic acids (levulinic, acetic and formic acid), and furan derivatives (hydroxymethyl fulfural) [9,27].…”
