The effects of toxicity on ethanol production
The production of ethanol is often impacted by the toxicity of feedstocks used. It is essential to understand feedstock-related toxicities’ adverse effects on ethanol production and to take measures to minimize their effects. Feedstock toxicity, a challenge for productivity and yield Organic acids, the principal inhibitors of fermentation Organic acids – such as lactic acid, […]
The effects of temperature on ethanol production
The success of ethanol production relies, partly, on various factors that can affect fermentation, with temperature playing a pivotal role. Yeast performance in converting feedstocks to ethanol is strongly linked to fermentation temperature, as it can only satisfy its needs under a suitable temperature environment. In this article, we will explore the effects of temperature […]

How does fermentation stress affect plant profitability? – Through the study of industrial ethanol production
Like all biochemical processes, we can evaluate fermentation performance using the following 3 Key Performance Indicators (KPIs): productivity, yield and titer. These 3 KPIs have a direct impact on industrial ethanol production cost and thus plant profitability. All fermentation stresses leading to an impact on one or several of these KPIs will also impact plant […]
How to choose the ethanol yeast?
Yeast is a key element in industrial ethanol production and each cell works like a production unit. From fermentable materials, yeast produces the major product ethanol and several co-products, such as CO2 and glycerol. As in the case of the production unit, the choice of yeast is an important technological decision that will have a […]
What is Yeast?
Yeast is a key element in the production of industrial ethanol, but do you know the specificities of this microorganism? Yeast is a unicellular fungus Yeast belongs to the family of the fungi. It consists of a large and diverse group of eukaryotic organisms, i.e. they possess organelles that divide the cell space into specialized […]
De-risking fermentation
“2014 was the year of second generation ethanol with the openings of several plants in North and South America. A number of other multi-partner global projects have also been announced or are currently under construction by major actors of the cellulosic ethanol scene. In the US alone, the E2 advanced biofuel market report published in […]
