Studies on the amino acids released by phyllosphere diazotrophic bacteria

A variety of amino acids was released into nitrogen free broth by three different phyllosphere diazotrophic bacteria. Glutamic acid, aspartic acid, serine and tryptophan were released into the broth by all the isolates. Azotobacter chroococcum(isolate REN 2) and Beijerinckia indica(isolate JN 1) lib...

Zusammenfassung:	A variety of amino acids was released into nitrogen free broth by three different phyllosphere diazotrophic bacteria. Glutamic acid, aspartic acid, serine and tryptophan were released into the broth by all the isolates. Azotobacter chroococcum(isolate REN 2) and Beijerinckia indica(isolate JN 1) liberated more different amino acids than Corynebacteriumsp. (isolate WN 2). The total amount of amino acids secreted by the different isolates was estimated.
