Abstract

Preliminary study on the preparation of bactopeptone (for use in bacteriological media) from shrimp (Penaeus indicus) head waste by papain treatment and its microbiological evaluation by lactobacilli is presented along with the chemical characteristics of the product. The shrimp head hydrolysate contained 13% N, 29.85% alpha-amino N, 0.60% fat and 0.48% tryptophan. pH was lowered from 8.0 to neutral by adding phosphoric acid; this also reduced the Ca level. Indole production was more marked with shrimp waste peptone than with a commercial sample. The growth rate of Leuconostoc mesenteroides and Streptococcus faecalis over 24 h was comparable to those grown on oxoid peptone.
