| Abstract: | 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.
