Abstract excerpt
L-Proline (Pro) is an essential amino acid additive in livestock and aquaculture feeds. Previously, we created a Pro overproducing Halomonas elongata HN6 by introducing an engineered salt-inducible Pro biosynthetic mCherry-proBm1AC operon and deleting a putA gene that encoded a Pro catabolic enzyme in the genome of H. elongata OUT30018. Here, we report a generation of a novel Pro overproducing H. elongata HN10...
