In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。
