Applications and Technical Notes

SMOD is ideal for Anaerobic culture monitoring

The SMOD can be used to monitor the growth of anaerobic cultures. The growth of the obligate anaerobe Clostridium difficile CCOS 941 was monitored using the SMOD. Cells were grown at a constant temperature (370C) with agitation (200rpm) and the Optical Density (OD600) and temperature measured by the SMOD over 14 hours is graphed. (data provided by Dr. G. Dasen, CCOS – Culture Collection of Switzerland AG) and ZHAW – Zurich University of Applied Sciences).

SMOD is ideal in experiments to obtain the optimum induction time for protein expression and monitoring of the culture during protein expression.

Figure 1. Using the SMOD for protein expression in Escherichia coli. To demonstrate the use of the SMOD to monitor E. coli cultures during induction and expression of proteins. E. coli BLIM cells were inoculated into LB medium at an OD600 of 0.05 and the growth was monitored with the SMOD at a 15 minute time interval until an optical density of 0.5 was reached (Black arrows) . The culture was grown at constant temperature (370C) with agitation (200rpm). Then the cultures were removed from the incubator to cool to room temperature before induction. Once the temperature had dropped, protein expression was induced by adding Arabinose (concentration, Red arrows), and the cultures were returned to a 200C incubator and incubated for 10 hours at constant temperature (200C) with agitation (200rpm). The Optical Density (OD600) and temperature measured by the two SMODs during the experiment is graphed.
