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 beberapa isolat Azotobacter dari lahan Eco Urban Farming ITS dalam mendegradasi karbohidrat (amilum dan selulosa). Kemampuan isolat dalam mendegradasi karbohidrat ditentukan dengan pengukuran Indeks Biodegradasi (IB). Isolat yang digunakan yaitu A1a, A1b, A2, A3, A5, A6, A7, A8, A9, dan A10. Semua isolat mampu mendegradasi amilum dan selulosa kecuali A8. Indeks Biodegradasi (IB) tertinggi terdapat pada isolat A5 yaitu 5,50 untuk amilum dan 3,50 untuk selulosa

Keywords


Azotobacter spp.; karbohidrat; biodegradasi
