Research was performed to select soil bacteria showing degradation of chlorpyrifos and producing antifungal activities. Strain BPTC-316 had the highest biological activity among 32 potential isolates using selective medium, culture characteristics and 16S rRNA gene sequence analysis. The strain BPTC-316 showed the closest similarity of 99.78% to Rhodococcus tukisamuensisJCM 11308T(AB067734) based on analysis of 16S rRNA gene sequence. BPTC-316 was able to degrade 96.8% chlorpyrifos after 10 days of incubation. In addition, the crude bioactive compound extracted from strain BPTC-316 was able to inhibit growth of Fusarium oxysporumKACC 41083 and Phytophthora capsiciKACC 40483 with antifungal diameters of 17.6 and 16.8mm, respectively.
