| Abstract: | The efficacy of powder formulations derived from Bacillus spp. was evaluated using nine Bacillus spp. isolates: B1-19, B2-2, B2-6, B2-21, B2-32, A1-2, A1-5, A1-12, and A1-15. Each isolate was prepared in three different forms: cell suspensions, culture filtrate, and a combination of cell suspensions and culture filtrate, which were then developed into powder formulations. The results revealed that all three powder forms-cell suspensions, culture filtrate, and the combination of cell suspensions and culture filtrate were able to inhibit the colony growth of Alternaria sp., with inhibition rates ranging from 45.85–71.88%, 48.08–70.07%, and 47.52–70.07%, respectively. |
