et al., 2007); (2) its GRAS (generally regarded as safe) status; (3) its
capacity to grow rapidly under anaerobic conditions, which helps
circumventing the oxygenation problems inherent to large-volume
industrial fermentations (Snoek and Steensma, 2007); (4) the extensive
industrial and scientific knowledge accumulated that makes
it one of the best studied organisms; (5) the possibility to use its
biomass as animal feed (co-product), which is important for industrial
