was prepared using the inoculum and allowed to stand for about 15 min. A well of 8 mm diameter was aseptically made at the center of each agar plate and 0.1 g of powder placed in the well. All treated plates including a control with only bacterial inoculation was incubated in an upright position for 48 h at 35 C. After incubation, the diameter of the inhibitions zones was measured, and it was confirmed that a bacterial lawn did form on the control plates. The screening tests were performed in triplicate, and the average results are reported here.
