摘要：

An LKB-2277 Bioactivity Monitor was used to determine thermogenic curve of the growth metabolism of Escherichia coli at 37℃. The experimental results indicate that the relation between cell concentration and power output can be characterized by the equations:C=kP+a,dC/dP0=KC1 where P is the power output (μW), C is cell concentration (mg·mL-1),P0 is the power output produced by the metabolism of one unit of cell (P0=P/0.6 C),k, a and K are constants which depend on the culture condition and physiological state of the cells.
