Potensi Pemanfaatan Isolat Bakteri Kitinolltik Lokal Untuk Pengendalian Hayati Jamur
MetadataShow full item record
A study on isolation of chitinolytic bacteria and an assay on their chitinolytic activity have been conducted. The purpose of the study was to isolate chitinolytic bacteria and to examine their chitinolytic activity, and also to know their potential in inhibiting growth of Fuforium semitectum, Ganoderma boninense, and Penicillium citrinum. The bacteria were isolated from soil of North Sumatra (Asahan, Deli Serdang, Labuhan Batu, Langkat, Medan, Padang Sidempuan, Tapanuli Utara, Toba Samosir). Twenty two chitinolytic bacteria were isolated. DS01 and LK01, and TS01 and KR01 showed similar morphological and biochemical characterization. PS01 has relatively high hydrolytic activity compared to others. DS01 and LK01, and LB02, KR03 and LK03 were able to inhibit growth. F. Semitectum and G. boninense growth, respectively, while LB01, LK01, KR03, KR05, and LK03 were able to inhibit P. citrinum growth. Some isolates were able inhibit growth of 2 different fungi.
