Nutrition in bioethanol production – White Paper

Addressing micro- and macronutrition deficiencies in bioethanol production to maintain yields and secure fermentations

Like any industrial process, ethanol production comes with high costs. With the feedstocks accounting for 50% of production costs and energy for 25%, it is crucial to reach maximum yields during production. Thus, optimizing every stage of ethanol production is very important to reduce feedstock waste and energy expenditure, which also have a major impact on a plant’s carbon footprint.

Addressing micro- and macronutrition deficiencies in biotechnol production to maintain yields and secure fermentations

While optimization can happen through various ways – temperature and pH optimization, propagation time, contamination monitoring, etc. -, addressing any nutrient deficiency in yeast is also crucial.

This paper details:

  • Micro- and macronutrition’s impact on yield, feedstock consumption and waste reduction
  • Nutrition deficiencies’ impact on fermentation completion and plant performances
  • Nutrition particularities in the cases of cellulosic feedstocks
