| 1 | Straw bio-degradation by acidogenic bacteria and composite fungi显示文摘A composite microbial system, including a strain of Candida tropicalis(W3), a strain of Lactobacillus plantarm(WY3) and three strains of basidiomycete pL104, pL113 and C33, was chosen to degrade corn straw. The final pH was acid owing to the inoculation of acidogenic bacteria, and under this condition the composite fungi system could produce complex enzyme to destroy the compact structure of corn straw. The experimental results showed that the biomass of composite fungi could reach up to maximum when the pH value was 4.5. Through the bio-degradation by combining acidogenic bacteria with the composite fungi system, the cellulose, hemi-cellulose and lignin degradation rates of corn straw powder were 26.36%, 43.30% and 26.96%, respectively. And the gross crude protein content increased 60.41%. This study provided the evidence for the feasibility of developing a composite microbial system with high capability of degrading straw lignocelluloses in order to make reasonable use of straw resource and protect rural eco-environment. | ZHANGKe-qiang CHENXiu-wei JIMin NINGAn-rong FANHuan ZHOUKe | 2004 | Journal of Environmental Sciences2004，16，4： | 3 |
| 2 | Screening of Cellulase Producing Fungus ZDTJ097-1-(7) from Bohai Bay and Its Yielding Conditions显示文摘[Objective] This study aimed to screen a marine-derived cellulase producing filamentous fungus and to investigate the yielding conditions and celluase activity.[Method] A total of 25 marine-derived filamentous fungus were screened out of from Bohai Bay,and one producing cellulase was obtained through Congo red transparent circle method and cellulase activity assay.After that,optimum conditions were examined for cellulase producing and catalyzing.[Result] CMC-Na could induce ZDTJ097-1-(7) strain to produce filter paper cellulase,CMC cellulase and β-glucosidase.The optimum conditions for ZDTJ097-1-(7) to produce enzymes were 0.5% CMC-Na,0.2% NH4NO3,pH 6.0 at 25 ℃.[Conclusion] This study provided reference for further development and utilization of cellulase producing fungus ZDTJ097-1-(7). | Shuang LI Fanhuan MENG Dan LIU Xin FENG Qingheng MENG Jianhua SUN | 2012 | Agricultural Biotechnology2012，1，1： | 0 |
