Potential of cellulolytic fungi isolated from the intestine of Asiatic rhinoceros beetle (Oryctes rhinoceros)

Abstract Cellulose is a potential source of fermentable sugars and promising cost-effective for biofuel production. This study aimed to obtain cellulolytic fungi from the intestine Asiatic rhinoceros beetle ( Oryctes L.). The were isolated using Potato Dextrose Agar (PDA) media spread plate method. Qualitative quantitative screening tests carried out 1% CMC (w/v) as sole carbon source. Twelve isolates recovered with varying capabilities. highest activity was obtained KOr-15J an index 1.93 while KOr-23J produced lowest (1.01) based on qualitative screening. cellulase assayed DNS (3,5-Dinitrosalicylic acid) method revealed KOr-21J 0.018 U/mL three (KOr-16J, KOr-19J KOr-22J) (0.003 U/mL). provides multiple verifications ability their in beetle.
