How can I test my bacteria at home?
The most common way would probably be to swab your solid surface and then rub that swab over a petri dish with bacterial growth agar. Then you just let the plates incubate and grow. Keep in mind that different types of bacteria grow on different growth mediums and at different temperatures, etc.
