Bioprocessing of shrimp wastes to obtain chitosan and its antimicrobial potential in the context of ethanolic fermentation against bacterial contamination

摘要

Titratable acidity (gray bars) and optical density (solid line) in the fermentation assays by L. plantarum in MRS medium containing 20 g L–1 (a, d), 100 g L–1 (b, e) and 150 g L–1of glucose (c, f) and 10% (upper panel) and 20% (lower panel) of bacterial inoculum (v/v), at 35 °C, 160 rpm, during 5 days of fermentation
