Is it a random stock photo?
It could be, but it is actually a portrait of our bacteria. They are kinda small, so we needed a good zoom - so we used a microscope.
To differ one thing from another we used a colouring. Nile Blue(some colouring stuff) staining of the sample allows the lipids to be observed. As a result of the dye application, fatty acids turn blue, while neutral lipids turn red or orange.
