What level of bacteria/yeast classification is possible using SEM?

02 February 2019 1 3K Report

I am working to use SEM to image bacteria/yeast in lichens to find where they live within lichens. We have images of bacteria as of now but it seams that without ultra-structural analysis higher levels of classification would be difficult.

What is your experience with imaging microbes in SEM and using morphological traits to identify them?

Nicolas Barois

Hello,

Talking about bacteria, SEM will give you the shape of the bacteria (cocci, bacilli, vibrio, filamentous etc.) as well as their behavior (mono, diplo, tetra, staphylo, strepto etc.)

For further classification, you will need genomic analysis. The shapes and behaviors will help you for what genomes you should look for.
