摘  要:
通过采用连续传代的纳豆芽孢杆菌种子液接种豆粕进行固体发酵,测定发酵产物中的细菌总数及活菌数,发现种子液传代次数对纳豆芽孢杆菌固体发酵的产量有很大的影响,同时菌种在多次连续传代后、会产生菌种退化现象。本试验研究表明,Na和N1型纳豆芽孢杆菌菌株自斜面培养基接种后进行4次传代,是比较合适的。

摘  要:
Bacillus natto passaged in a row,then were carried in solid-state fermentation of soybean residue. Measuring the number of total bacteria,it was showed that the number of spead generation of bacillus natto had strong influence on yield of bacillus natto solid-state fermentation.To two bacillus natto lines(Na and N1) which were used in the experiment,it was necessary to change the liquid inoculated substrate after bacillus natto has four passage times from the inclined plane substrate.
