Background:

Traditional bulk bioreactors are reagent-intensive and difficult to maintain.
Miniaturized systems are needed to overcome the limitations of conventional microbial culture methods.

Purpose of the Study:

To develop a microfluidic bioreactor that mimics macroscopic serial dilution transfer culture.
To enable automated, long-term microbial cultures with minimal reagent consumption and real-time monitoring.

Main Methods:

A microfluidic device with two compartments and discrete time, periodic dilution steps was designed.
The device operates at a nanoliter-scale working volume.
Real-time monitoring of microbial populations at single-cell resolution was implemented.

Main Results:

The microfluidic bioreactor successfully mimicked macroscopic serial dilution transfer culture.
Automated, long-term microbial cultures were achieved with nanoliter volumes.
The device facilitated real-time, single-cell resolution monitoring of microbial populations.
The high surface-to-volume ratio enabled effective biofilm-flow reactor operation, supporting cogrowth of planktonic and biofilm populations.

Conclusions:

The developed microfluidic bioreactor offers an efficient and automated platform for microbial culture.
This technology reduces reagent consumption and maintenance efforts compared to bulk bioreactors.
The device's capabilities are expected to advance various fields within microbiology, including fundamental research and applied biotechnology.
