摘要：为进一步提高肉桂叶发酵过程中各种饲用酶活性,通过I-optimal混匀设计考察了不同食用菌菌种间,以及食用菌与米曲霉间混合发酵产饲用酶活性的协同与拮抗效应。研究结果表明:特殊立方模型可以作为实验设计的回归模型,拟合结果可靠。在平菇、金针菇、木耳与米曲霉间,金针菇与木耳的菌丝产酶过程中存在拮抗效应,其余菌种生长过程中显示出明显的协同效应。通过数值优化算法得出2个最佳接种配比方案:配方一为17.6%木耳、44.4%平菇和38.0%米曲霉,对应的木聚糖酶酶活为9.14 U/g、纤维素酶酶活为1.56 U/g、植酸酶酶活为67.37 U/g;配方二为60%金针菇和40%米曲霉,对应的木聚糖酶酶活为5.74 U/g、纤维素酶酶活为1.34 U/g、植酸酶酶活为58.39 U/g。
To achieve higher enzymes activities during fermentation process of cinnamon leaves,the synergetic and antagonistic effects among different edible fungi,as well as between edible fungi and Aspergillus oryzae,were estimated by I-optimal mixture design.The results demonstratedthat special cubic models fit the mixture design methods well.Among Pleurotus ostreatus,Flammulina velutipes,Auricularia auricular and A.oryzae,antagonistic effects were found between F.velutipes and A.auricular during enzyme production,and synergistic effects were found among the rest species.Thus,by taking advantage of synergetic effects and avoiding of antagonistic effects,two formulas were made as following:A.auricular 17.6%,P.ostreatus 44.3%and A.oryzae 38%(9.14 U/g xylanase,1.56 U/g cellulose,67.37 U/g plant enzyme);or F.velutipes 60%and A.oryzae 40%(5.74 U/g xylanase,1.34 U/g cellulase,58.39 U/g plant enzyme).
