PREPATION TOW PROTEIN HYDROLYSATES FROM
Abstract
Abstract
Two protein hydrolysates were prepared from animals by-product (chicken
legs(A) and raw shrimp waste(B)) by chemical method (hydrochloric acid). The
chemical composition of Protein hydrolysates that include percentage of total solid
matter, total nitrogen, Protein,lipid,ash ,yield and degree of analysis were studied, Also
the physical properties of Protein hydrolysates were studied (pH and color), The best
concentration of hydrolysates for preparing media was 4% for A and B, The Protein
hydrolysates were added to two types of media (peptone broth and agar) and (nutrient
broth and agar) instead of their peptone .Their ability to support the growth of
microorganisms by cultivating natural samples (water, soil,milk and meat). The samples
were incubated in 37C
