“The new method from Finland is based on bacteria that grow under aerobic conditions, using methane as a source of carbon and energy. The end product is a single-cell protein biomass with a protein content of around 60 percent. Filtered, pasteurized and dried, the material has potential as a high-quality feed ingredient. Previous studies have shown that single-cell proteins can be an effective substitute for ingredients such as meat, soybean, egg whites or fish in animal feeds and human food.” – via WATTAgNet.com
The Technical Research Centre of Finland has come up with a method to convert methane-rich biogas into high-protein raw material for animal feeds.
