Abstract
Ensilation of shrimp .waste was carried out with of Lactobacillus fermentum at room
temperature (30+loC). Formic acid (0.4%) was used to adjust the pH to 5.8 at the start of
the experiment. The pH of the medium fell sharply from 5.8 at the beginning to around
4.5 by 2'ld day and was more or less stable during the remaining part of ensilation. The
protein content of the residue showed a decrease with a proportional increase in chitin content.
The ash and crude fat content registered a decrease. The data on biochemical composition
of the slurry revealed that the protein content, a amino nitrogen and NPN increased
substantially during fermentation. The TVBN value remained constant at about 0.07% on dry
weight basis during the period of observation. Protein solubilization of the order of 60%
obtained during the present study was independent of initial bacterial density and is within
the range of acceptability indicating that L. fermentum is an ideal candidate for use in
biofermentation of shrimp waste
