Novozymes adds yeast to bioenergy business
Back to list
Novozymes today revealed its new yeast platform for starch-based ethanol, while also introducing the first product, Innova Drive. A completely new yeast strain, the product can reduce fermentation time by up to two hours compared to current yeasts.
Recent surveys show that more than half of all ethanol plants face operational upsets, many related to yeast. High heat, infections, organic acids, and throughput limitations are stressors that plague current yeasts, requiring plant personnel to increase antibiotics, reduce inputs such as corn solids, and add more yeast-all contributing to process complexity. This leads to a double-impact of increased costs and lost revenue.
