第二章 微生物代谢调节微生物的新陈代谢错综复杂，参与代谢的物质又多种多样，即使同一种物质也会有不同的代谢途径，而且各种物质的代谢之间存在着复杂的相互联系和相互影响。微生物的生命活动是由产能与生物合成的各种代谢途径组成的网络，互相协调来维持的。 可以把微生物看作是一个奇妙的超微型化学工厂。Figure 2: Interactions between functional groups. Numbers in parentheses indicate, first, the number of interactions within a group, and second, the number of proteins in a group. Numbers near connecting lines indicate the number of interactions between proteins of the two connected groups. For example, there are 77 interact
