Algae may replace fish oil in salmon feed

Fish oil is an ideal source of omega-3 in salmon feed, but the capacity to produce farmed salmon using fish oil as the main source of omega-3 in feed is limited, if the farmed salmon itself is to remain a rich source of omega-3. This means that the salmon feed industry needs access to large volumes of new ingredients that contain omega-3. Experiments at Nofima have shown that a type of algae known as “heterotrophic algae” can fully replace fish oil in feed used for small salmon. Continue Reading →

Efficient production of hydrogen by algae

Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. In the current issue of Energy and Environmental Science scientists from the AG Photobiotechnology of the Ruhr University Bochum and the Max Planck Institutes in Mülheim present how an improvement in efficiency can be achieved.
