Potensi Bakteri Denitrifikasi Dalam Biodegradasi Carbaryl Pada Kondisi Anaerobik

Potency of denitrifying bacteria on carbaryl degradation under anaerobic condition was studied. Firstly, we acclimated and isolated denitrifying bacteria from the pesticide polluted-agriculture soil at Lembang and Dieng. Three microbe culture of denitrifying (C.L, C.D and D3) was obtained and all of the cultures indicated having growth capability on media containing 1000 ppm of carbaryl. Ten isolate of denitrifying bacteria was obtained from those three microbe cultures. Furthermore, the denitrifying activity and capability of carbaryl degradation of six isolate of denitrifying bacteria (CL1, CL2, CD1, CD2, D3.1, D3.2) were tested under anaerobic condition. The result shows that the denitrifying reaction and carbaryl degradation were carried out simultaneously. From the experiment found that there were two kind pathway of carbaryl degradation. The first pathway was carbaryl to 1-Naphtol, the second was carbaryl to 1-Naphtol, and 1-Naphtol to certain compound (was not detected yet). Jurnal Teknologi Lingkungan, Vol. 12, No. 3. 2011.
