The microbiological assay of the “essential” amino-acids in compound feedingstuffs
Abstract
A re-examination has been made of the methods in current use for the microbiological assay of the “essential” amino-acids arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine, and improvements in basal media and methods of hydrolysis are suggested.
