Optimization of an integrated grain-biomass-ethanol supply chain with event-based decision-making
… renewable energy in the US, but high investment costs and low energy yield often slow the adoption of renewable technologies. When considering biomass for fuel production, farm and distribution management become key in turning such renewable alternatives into successful large-scale systems. This …

Bio-enrichment of vitamin B12 in plant-based food via fermentation
Vitamin B12 deficiency is common among individuals following strictly plant-based diets. This issue is amplified by the growing preference for organic products, which are often not vitamin-fortified. As vitamin B12 is naturally produced by bacteria, fermentation offers a sustainable strategy to …

GENERATING BIOENERGY AND HIGH-VALUE PRODUCTS FROM HIGH SALINITY FOOD WASTE
… were explored using anaerobic digestion and dark fermentation processes, respectively. This study tested adding value to three organic waste streams: household food waste, high salinity food processing waste (composed of glycerin sludge from biodiesel production), and residual solids from VFAs …

Development of fortified blended food and the effect of selected parameters on its composition and functionality
… blending heat-treated, dehulled cereal (wheat, corn or rice), dehulled beans, skim milk powder, sugar, soya bean oil, vitamin/mineral mix, dicalcium phosphate and potassium chloride. FBF is reconstituted and cooked to a porridge or soup prior to consumption. The consistency of the porridge is …

Engineering Zymomonas mobilis for efficient fuel ethanol production from lignocellulosic feedstocks
… Zymomonas mobilis is of interest for the commercial production of fuel ethanol from lignocellulosic feedstocks due to its high ethanol productivity. Z. mobilis has been engineered to ferment all of the sugars present in cellulosic biomass, but the digestion of five carbon sugars by the …

Improving advanced biofuels production in Saccharomyces cerevisiae via protein engineering and synthetic biology approaches
… lignocellulosic biomass. However, we are still encountering several challenges to achieve cost-effective production of cellulosic biofuels, such as the sequential utilization of sugar mixtures caused by glucose repression and the low efficiency of synthesizing fatty acid derived advanced biofuels. …

Design of a Saccharomyces cerevisiae strain capable of simultaneously utilizing cellobiose and xylose
… production from lignocelluloses. However, glucose repression limits efficient ethanol production because glucose in lignocellulosic hydrolysates inhibits xylose and other sugars’ utilization. As a result, it is attractive to construct a glucose derepressed S. cerevisiae strain for efficient …

Engineering and evaluation of yeast strains for the production of lactic acid from cellulosic sugars
Terrestrial biomass consists largely of lignocellulosic materials. Abundant in nature, lignocellulosic biomass can be cultivated easily on land otherwise unsuitable for traditional crops or be harvested from crop waste, such as corn stover. After pretreatment and hydrolysis, the lignocellulosic …

Engineering Saccharomyces cerevisiae for cellulosic ethanol production
… one is inefficient xylose utilization and the second one is sequential fermentation of glucose and xylose in engineered Saccharomyces cerevisiae. This study mainly focused on solving these two problems by using cutting edge synthetic biology tools.

Enhanced bioethanol fermentation from mixed xylose and glucose using free and immobilized cultures: mathematical model and experimental observation
… is produced from edible food crops such as corn and sugarcane that causes an increase in demand for vacant lands for food production and, subsequently, increase in the cost of food manufacturing. Therefore, alternative raw materials for bioethanol production are sought after, such as …
