Abstract: In this paper,rice straw was used as main material to produce feed enzyme-complex by solid state fermentation of Neurospora sitophila,then the effective factors on pH and temperature were decided. The results showed that the stability of feed enzyme-complex activity is the optimization under the condition of pH 3.0~5.5 and 30~40℃.
