Amino acid analysis is widely applied in research, clinical facilities, and industry. It is a fundamental technique in biotechnology, used to determine the concentration of peptide solutions, to confirm protein binding in antibody conjugates, and for end-terminal analysis following enzymatic digestion. Clinical applications include diagnosing metabolic disorders in newborns. In industry, it is used for quality control of products ranging from animal feed to infant formula. 

This continual modification of the process allowed it to compete with the petrochemical synthesis of butanol and acetone (see sections 9.8.1 and 9.9.7 of Vol. I) (Figure 6.6), until molasses found a competing use as an animal feed and its price began to rise. British production stopped in 1957, but the process survives in South Africa and Taiwan, where oil supplies are limited. A process which made use of waste cellulose might still be economic. However, its main legacy to biotechnology lies in that early phase of its development which laid the foundations of the modern fermentation industry.
