|Filamentous bacteria from soil, seen with phase contrast microscopy.|
The isolated bacterial species will vary with the conditions (type of medium, temperature); here I found many filamentous bacteria on the plate. They look a little bit like filamentous fungi (since they also form a mycelium), but usually you can easily tell them apart (with a microscope) because of their smaller diameter.

As seen with phase contrast microscopy, spores are bright and refractile objects that are easily recognizable, for instance in the images below.

It is good to remember that not all bacteria look like E. coli!
