Instrumentation of On-Line Detection of Microbial Density

Abstract:

Microbial density is an important biochemical parameters of the training process. This article adopts the method of online measuring optical density of the reactor to obtain information on the growth of microorganisms, and flow photoelectric colorimetric instrument was developed based on this principles. Through MCU STM32F107VC output PWM to control peristaltic pump, to achieve the culture of continuous flow through the optical flow cuvette, using photocell to detect culture absorbed light intensity. The instrument can display detected parameters independently and adjust the control parameters, also can communicate with the PC by RS485. The instrument can achieve real-time monitoring of the growth of microorganisms in the reactor.
