Abstract:

Using clodinafop propargyl (CF) as a sole carbon, nitrogen and energy source, a CF-degrading bacterial strain was isolated from crop soil field. This strain was identified as Pseudomonas sp. strain B2 by 16S rRNA gene sequence analysis. 87.14 % CF was degraded out of initial provided 80 mg/L CF. Degradation of CF was accompanied by release of chloride ion. The optimal pH and temperature for the growth of B2 were 7.0 and 30°C, respectively in the mineral salts medium supplemented with CF. An actively growing culture of strain B2 degraded CF to clodinafop acid and 4-(4-Chloro-2-fluoro-phenoxy)-phenol within 9 h, as determined by GC-MS analysis. A metabolic pathway for the degradation of CF by B2 has been proposed
