Fish Hydrolysates. IV. Microbiological Evaluation

摘要

SUMMARYMicrobiological evaluation was made of three experimental fish hydrolysates (peptones) prepared in this laboratory from a fresh‐water species of fish,Barbus dubious.Ten selected microbial cultures grown in an inorganic basal medium with and without yeast or meat extract and containing different concentrations of hydrolysates, showed more or less the same growth in all the hydrolysate media. Media containing the hydrolysates were sensitive to antibiotics. The hydrolysates were quite suitable as ingredients of culture media for biochemical tests like indole and methyl‐red reactions. Controls were two commercial peptones, one commercial proteose‐peptone, and one commercial try
