“…The fish processing industry generates large quantity of liquid and solid wastes, and due to their high protein content, they have been proposed as alternative for preparation of valuable products (Kim & Wijesekara, ; Ferraro et al., ; Rustad, Storrø, & Slizyte, ). Peptones obtained from fish‐processing waste have demonstrated that can produce high amounts of bacteriocins from L. sakei Lb 706 (Deraz, El‐Fawal, Abd‐Ellatif, & Khalil, ), up to 500% more than the quantity obtained using commercial media.
