Most cold-active α-amylases show highest activity at app. 30ºC. However, with a temp. optimum at 5-20ºC, AmyI3C6 outperforms the existing cold-active α-amylases in the market. AmyI3C6 yields societal implications in the detergent, bakery, and beverage industries, as it can make these industries greener. The environmental impact of cold-active α-amylase in detergent amounts to 0.3 kg of CO2 per 3 kg of laundry. Further, if all Danish households reduced laundry temperatures to lukewarm water, annual savings would be EUR 67 mio. For beverages, savings amount to 2.5 kg of CO2 per 100 L of beer produced, and for bread, 5.4 kg of CO2 per 100 units of white bread. Thus, AmyI3C6 goes far beyond state-of-the-art for cold-active α-amylases.
