Effect of the heterologous expression of the MatBC enzymes upon malonate feeding. The S. albidoflavus UO-FLAV-002 strains bearing one or two copies of the naringenin BGC were cultured in NL333 (white) and NL333 with malonate 20 mM (grey). Naringenin concentration was measured 48 h after inoculation. The folds of the increase in naringenin production are depicted
