Sea lettuce is grown in tanks (IMAGE) Chalmers University of Technology Caption Proteins from seaweed, such as sea lettuce, have the potential to become an important food component. However, the proteins are often tightly bound, but now researchers at Chalmers University of Technology, in Sweden, have found a new way to extract these proteins three times more efficiently than before. Here, sea lettuce is grown in tanks containing water that was previously used in the seafood industry. Through this cultivation, they take up nutrients that would otherwise have been discarded.
