摘　　要：选用青霉菌（Pemicillumsp）用于纤维素酶液体深层发酵条件和生产工艺的研究。研究了纤维素酶二级和三级液体培养的条件。确定了种子液和发酵液的配方、产酶活力FPA167单位／毫升、β-葡聚糖酶活力20万单位／毫升。为纤维素酶三级液体深层发酵的工业生产提供了工艺路线和参数。Enicillum sp was uted to study the deep fermentation condition and the preduction technol-goy of cellulase. Two and three stage liquid cultivation of cellulase was studied, and the form ofbreeding medium, fermentation medium was determined too.The activation of cellulase was167u/ml, that of β- glucanase was 200000u/ml.The technological process and the Parameterwere provided for the industrial production of cellulase in three stage deep fermentation.
