Biotechnological deproteinization of shrimp waste (Litopenaeus vannamei) using bacterial consortia

Abstract

Deproteinization of shrimp waste (Litopenaeus vannamei) was achieved by biotechnological treatment using bacterial consortia. Five bacterial consortia (CB01, CB02, CB03, CB04 and CB05) were separately evaluated under a factorial design 23, including the effect of temperature (25 and 35 °C), time (16 and 24 h) and volume of inoculum (2 and 6 mL × 107 CFU/mL). Bacterial consortium CB05 showed the highest deproteinization (DP) effect. The best response was achieved at 35 °C, 6 × 107 CFU/mL, and 16 h of bioprocess. Protein content was reduced by 99.5 %. © 2024 Elsevier B.V., All rights reserved.
