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...
متن کاملBioconversion 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...
متن کاملBiochemical 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...
متن کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
متن کاملAcetylation Modification of Rice Straw Fiber and Its Thermal Properties
The esterification of rice straw fiber with acetic anhydride, using sulphuric acid as catalyst, under mild conditions in glacial acetic acid, has been investigated. Acetylation conditions, such as dosage of chemicals and catalyst, and time and temperature of acetylation, were optimized. The preferred reaction parameters of acetylation reaction are described as follows: weight ratio of rice stra...
