title: Effect of amino acids on rapamycin biosynthesis by Streptomyces hygroscopicus.
abstract: In a chemically defined medium containing aspartate, arginie and histidine to support good growth, addition of L-lysine stimulated rapamycin production by 150%. This was probably due to its conversion to pipecolic acid, a rapamycin precursor. Phenylalanine and methionine interfered in rapamycin production by unknown mechanisms.
