复合菌株发酵猪血粉的条件研究*

利用筛选出的2株高产蛋白酶的米曲霉(Aspergillus oryzae)菌株AS100、AS102作猪血粉发酵的主发酵菌株，配以1株酵母菌(Saocharomyces cereisiae)菌株Y113和1株细菌(Bacilus sp．)菌株Asp007为辅助菌株，研究了这四株菌的产酶性能，同时确定了它们在发酵血粉过程中的一系列参数。通过猪血粉发酵，获得了一种高蛋白发酵饲料，其香味浓郁，蛋白质含量高达69％，且富含游离氨基酸，VitD3、烟酸等维生素及Fe等无机元素，可作为禽畜高蛋白源或饲料添加剂。

STUDY ON CONDITIONS OF SWINE BLOOD MEAL FERMENTATION WITH COMPOUND STRAINS

Two high protease producing strains, whic h are desi gnated Aspergillus oryzae AS100 and AS102, were screened and applied as main fermentation strains of swine blood meal. A Saccharomyces cerevisiae Y113 and a Bacillus Asp007 were also used as assistant fermentation strains. The enzyme production abilities we re studied,and a series of parameters of the fermentation technology were deter mined. Through swine blood meal fermentation, a high-protein fermented feed wa s produced, which is strong soy flavor and was rich in protein(69%), free amino acid, vitamin such as VitD 3 and niacin and organic elements such as Fe. It is a kind of high-protein feed for animals and it could be used as feedstuff addi tive.
