摘要
以新鲜的猪血制取的猪血粉作为培养主要基质进行产纤溶酶菌株的筛选,经平板法初筛,从3个不同来源的豆豉样品中筛选出10株较高纤溶活性的菌株。通过摇瓶复筛确定1个产酶活性最高的菌株HN3,液体发酵确定其产酶最适温度、时间分别为30℃9、6 h。
With the fibrin plate method, ten strains which have fibrinolytic activity were screened from three different souices of lobster sauce samples collected from H unan, Jiangxi and Guizhou respectively. The pig blood powder which prepared from the fresh pig blood were the main substrate for the strains screening. After further selection, one strain named HN10 with the highest fibrinolytic activity was found. The optimal fermentation condition was 30 ℃, 96h.
