Isolasi dan Karakterisasi Bakteri Pendegradasi Herbisida Diuron dan Bromacil dari Area Perkebunan di Lampung

Diuron and bromacil are a broad-spectrum herbicide that widely used in some plantation at Lampung. We collected soil sample from variety location at banana Plantation (NTF), pineapple plantation (GGPC) and sugarcase plantation (GM). Our research’s aim were to isolation and characterization of diuron and bromacil degrading bacteria. The highest diuron resistant bacteria was found in GM soil sample and NTF soil samples have the highest bromacil resistant bacteria. We obtained three isolates for diuron degradation and five isolates for bromacil degradation bacteria from NTF, GGPC and GM. These isolates were tested to explore their ability for diuron and bromacil degradation on different concentrations. Isolation of bacteria used enrichment culture method and degradation of diuron and bromacil were checked by spectrophotometric method. Diuron and bromacil degradation by 5 consortium indicated that all of consorsia have ability to degrade them. Berkala Penelitian Hayati (Journal of Biological Researcher). Vol. 17 No. 1. Desember 2011
