A bioluminescent Escherichia coli auxotroph for use in an in vitro lysine availability assay.

Journal of microbiological methods - 1 May 2000

Erickson A M, Díaz I B, Kwon Y M, Ricke S C

Abstract excerpt

Microbiological methods have been used to determine the amino acid availability of a variety of animal feed and human food protein sources. Growth of Escherichia coli auxotrophs have been shown to yield a consistent linear response to lysine concentration when compared to chemical measures. Extent of total growth of E. coli lysine mutant (American Type Culture Collection #23812) when measured as optical density...
