Effect of Peptone on Azotobacter Morphology

Vela, G. R.
RESUMO
Pleomorphism in cultures of Azotobacter vinelandii was induced by addition of Difco peptone to the growth medium. Under the conditions of the study, 5% peptone gave rise to transient forms described as “fungoid cells” which were osmotically fragile. After some 48 hr of culture, they became osmotically stable and resumed a more typical morphology. It was shown that the pleomorphism-inducing principle in peptone was glycine.
