Amino Acids and Related Compounds 



a-aminoadipic acid, 3,4-dihydroxyphenylalanine, ethanolamine 

 and taurine. 



The amino acids of some algae have been reported,^ and also 

 those of Fusariinn lycopersici:' A quantitative study was made 

 of the amino acid composition of Usiilago maydis fermentation 

 broth.' Of the 3.5 mg. per milliliter of NH4" nitrogen added, 

 2.9 mg. per milliliter remained extracellular. This extracellular 

 nitrogen contained 1.17 mg. per milliliter of organic nitrogen 

 and 1.74 mg. of residual NH4* nitrogen.

 Amino Add Composifion of Usfilago maydis Fermenfafion Broth 



* The amino acids in the hydrolyzed broth and the bosic amino acids in the unhydrolyzed broth were 

 separated chromatographically and assayed colorimetrlcally. The other amino acids in the unhydrolyzed 

 broth were assayed microbially. 



t Values expressed as ^gm. per milliliter in terms of original broth. 



t Valid microbial assays were not obtained.
