Abstract

Nitrogenase activity ( = acetylene reduction activity) was observed in Azospirillum brasilense cultures grown on conditioned medium obtained from embryogenic pearl millet (Pennisetum americanum) and Guinea grass (Panicum maximum) cell suspension cultures, but no bacterial growth or activity was observed on unconditioned medium. A peak of maximum activity was obtained with medium harvested mid-way through a 13 d culture period. Non-embryogenic suspension cultures of pearl millet and Guinea grass supported little or no bacterial growth or nitrogenase activity
