Degradation of fenitrothion by Bacillus stearothermophilus adhering to silica.
B. stearothermophilus strain AG-49, when cultivated in mineral medium in the presence of silica (SA), adhered to SA. Adhesion depended on age of culture, contact time and glucose concentration of the culture medium. Mid-exponential phase culture (5 h) required minimum contact time (30 min) for maximum adhesion. 0.6% glucose concentration was optimum. Quantitative variation in protein and saccharide extractable in sodium chloride and sodium dodecyl sulfate (SDS) was observed. Five % degradation of fenitrothion by adherent B. stearothermophilus could be achieved in 4 d.
