Abstract

Azotobacter spp. merupakan salah satu genus bakteri nonsimbiotik yang berperan penting dalam bidang agrikultur terkait kemampuannya memfiksasi nitrogen. Penelitian ini bertujuan untuk mengetahui potensi isolat Azotobacter dari lahan Eco Urban Farming ITS dalam mendegradasi lipid dan protein. Kemampuan isolat dalam mendegradasi lipid dan protein ditentukan dengan pengukuran Indeks Biodegradasi (IB). Isolat yang digunakan adalah A1a, A1b, A2, A3, A5, A6, A7, A8, A9, dan A10. Semua isolat mampu mendegradasi lipid kecuali A5, dengan IB tertinggi pada isolat A1b (1,00). Semua isolat dapat mendegradasi protein kecuali A7, dengan IB tertinggi terdapat pada isolat A8 (3,00).

Keywords

Azotobacter spp.; lipid; protein; biodegradasi
