| 摘 要： | 为了筛选到发酵猪血的优良菌株，利用平板划线法，从农村个体屠宰场土壤中分离获得了菌株B60，该菌株在以猪血为惟一氮源的培养基上生长旺盛且蛋白酶活力强，利用B60菌株发酵猪血粉，使猪血粉的蛋白质含量下降了44．8％，氨基酸态氮含量上升了8．25倍，可溶蛋白含量上升了190％，说明B60菌株是1株发酵猪血的优良菌株。

| Abstract: | To find fine strains to ferment swine blood,by filtering the fermentable blood meal strains,we have obtained some strain B60 which grow bloomingly on culture medium and its protease activity are superior.Quality of B60 strains fermenting swine blood meal showed that protein of blood meal decreased 44.8% while N of amino in blood meal increased 8.25 times,soluble protein of blood meal increased 190%.All indicate that B60 is a fine strain to ferment swine blood. |
