Seventy-six bacterial isolates were obtained
from soils surrounding Zingiberaceae plants.
Among these, 28 isolates were cocci, 16 were
short rods and 32 were rods. After testing
their ability to inhibit growth of the pathogenic
bacteria PT1J, only five, namely N9C8, N9A,
N11IV, Ba3 and Ba4, displayed a high ability,
with inhibition zones ranging from 15-22 mm
(Table 1 and Figure 2).
