Scanning electron microscopic examination of a pellet formulation of Bacillus megaterium and B. pumilus,antagonists of Rhizoctonia solani,and survival during storage

Bacterial formulations, produced using both Bacillus megaterium and B. pumilus individually with pharmaceutical technology, were formulated using a wet granular method. Viability testing in the laboratory revealed that bacterial populations rapidly declined during storage at room temperature (26–30 °C) for 6 months. The scanning electron microscope (SEM) was used to observe bacterial formulations. Both endospores and vegetative cells of B. megaterium and B. pumilus were detected on the formulation surfaces.
