    Abstract
    An isolation and examination of crude chitinase of thermofilic bacteria were carried out in Laboratory of Microbiology, Departement of Biologi, FMIPA, USU from Februari to June 2008. The objective of the study was to isolated and to know the optimum temperature of the chitinase activity of bacterial isolates from Tinggi Raja hot spring. Five isolates (TR1, TR2, TR3, TR4, TR5) were selected for futher study. TR4 and TR5 showed optimum temperature of chitinase activity at 60oC by releasing 0.042 μmol/ml and 0.030 μmol/ml N-acetylglucosamine, respectively, while TR2 and TR3 showed optimum temperature at 65oC by releasing 0.025 μmol/ml and 0,019 μmol/ml N- acetylglucosamine, respectively. However, chitinase activity of TR1 have not been determinate yet since by of 70oC the activity was still increase .
     
    Isolasi dan pengujian kitinase kasar bakteri termofilik penghasil kitinase telah dilaksanakan di Laboratorium Mikrobiologi Departemen Biologi, FMIPA USU dari Bulan Februari 2008 sampai dengan Juni 2008. Tujuan penelitian ini adalah untuk mengisolasi dan mengetahui suhu optimum aktifitas kitinase bakteri yang diisolasi dari sumber air panas Tinggi Raja. Lima isolat (TR1, TR2, TR3, TR4, TR5) telah diseleksi untuk pemeriksaan lebih lanjut. TR 4 dan TR 5 menunjukkan suhu optimum dari aktifitas kitinase adalah 60oC dengan melepaskan 0.042 μmol/ml dan 0.030 μmol/ml N- asetilglukosamin,berturut-turut, kemudian TR 2 dan TR 3 menunjukan suhu optimum 65oC dengan melepaskan 0.025 μmol/ml dan 0,019 μmol/ml N-asetilglukosamin. Aktifitas kitinase TR1 belum dapat ditetapkan, sebab pada suhu 70oC aktifitas masih meningkat
