Isolation and characterization of cellulolytic bacteria from decomposing rice straw

Rice straw-decomposing fungi and their cellulolytic and xylanolytic enzymes.

Filamentous fungi colonizing rice straw were collected from 11 different sites in Korea and were identified based on characterization of their morphology and molecular properties. The fungi were divided into 25 species belonging to 16 genera, including 14 ascomycetes, one zygomycete, and one basidiomycete. Fungal cellulolytic and xylanolytic enzymes were assessed through a two-step process, whe...

Bioconversion of Straw Into Improved Fodder: Mycoprotein Production and Cellulolytic Acivity of Rice Straw Decomposing Fungi

Sixty two out of the sixty four species of fungal isolates tested could produce both exo-β1,4-gluconase (C1) and endo-β1,4-gluconase (Cx) on pure cellulose and rice straw as carbon source in Czapek's medium. Fifty-eight and fifteen species were able to grow at 25℃ and at 45℃, respectively. Eleven species could grow at both 25℃ and 45℃ while, four species appeared only at 45℃. The most celluloly...

Biochemical characterization and synergism of cellulolytic enzyme system from Chaetomium globosum on rice straw saccharification

BACKGROUND Efficient hydrolysis of lignocellulosic materials to sugars for conversion to biofuels and chemicals is a key step in biorefinery. Designing an active saccharifying enzyme system with synergy among their components is considered a promising approach. RESULTS In this study, a lignocellulose-degrading enzyme system of Chaetomium globosum BCC5776 (CG-Cel) was characterized for its act...

Isolation, Identification and Evaluation of Oil Hydrocarbon Decomposing Bacteria from Contaminated Areas of Oil Fields

Microbialbiodegradation is known as an effective and harmless method to overcome environmental pollution with oil hydrocarbon. Some bacterial species were isolated from the Sarvestan oilfields (Iran, Fars province), then identified and applied for oil hydrocarbon decomposition. A carbon-free minimum medium (CFMM) containing 1% crude oil was used to isolate bacteria through incubation at 30°C in...
