The flow cytometer allows rapid counting of any bacterial suspension. Combined with fluorescent viability/mortality markers, it is possible to count the total, viable and dead yeasts or bacteria present in a suspension in less than 30 minutes. This allows you to quickly assess the impact of your plastic on microbial development. This technique can be adapted to different types of samples, a set of microbial communities and different biological conditions.

With this technique we can study an entire microbial community, even those viable non-culturable ones (VNC) which cannot be demonstrated on Petri dishes.
