Biotechnological Valorization of Food Marine Wastes: Microbial Productions on Peptones Obtained from Aquaculture By-Products
Based on a biotechnological strategy, in the present work several peptones are produced from the Alcalase hydrolysis (0.1–0.2% v/w, 56–64 C, pH 8.27–8.98, 3 h) and thermal processing (105 C, 60 min) of wastes generated from the industrial processing of turbot, salmon, trout, seabream and seabass.
