From the above (table 4 and figure 2), only 3 actinomycetes isolates (CT 4, CT 5 and CT 6) inhibited one or more indicator bacteria. Some of the zones of inhibition were present but not very obvious (figure 2). The widest inhibition zone (diameter = 12.5 mm) was recorded for CT 4 which inhibited only the growth of P. aeruginosa. The narrowest inhibition zone (diameter = 7mm) was observed in CT 6, which also inhibited two other indicator organisms (B. subtilis and S. epidermis) (table 2). Meanwhile CT 1, CT 2 and CT 3 were not seen to inhibit any of the indicator organisms.
