发酵菌

We selected the 2nd and the 3rd generation yeast with powerful vitality from the yeast mud fermented in tanks in working field as the ideal species source separated from yeast monoplast in beer and the ways to obtain them were as follows: 24 hours after deoxidisation of diacetyl to threshold value and decrease of its temperature to 5℃ was the best time for selection and sample－extraction location was at the nozzle of pressure－discharge pipes.

摘 要：从生产现场大罐发酵的酵母泥中选取第2～3代生命力强的酵母作为啤酒酵母单细胞分离的理想种源，选取的最好时间为双乙酰还原至阈值后降温至5℃，并让其停留24h时取样位置为排压酵母的管口，最后将所得菌种进行初选、复选或模拟生产恒温培养鉴定，选出优良菌株。

Meanwhile, we evaluated parameters involved in the models for Morchella growth, EPS production and substrate consumption.
