In Norway, five researchers at the University of Bergen (UiB) and Uni Research have found that a certain type of tunicate – ascidiacea – can be used as a renewable source of biofuel and fish food. It is the cellulose, the protein, and the Omega-3 fatty acids in the ascidiacea that is the cause for its many uses. Its mantle consists of cellulose, which is a collection of sugars. When cellulose is cleaved, one can obtain ethanol. And ethanol can be used for biofuel in cars. The animal’s body consists of large amounts of protein and Omega-3. This can be used for fish feed, says Professor Eric Thompson at UiB’s Department of Biology.
