Mold types

I work for a group home and recently was made aware of a toilet backup in February that caused an inch or so of water to sit in the basement, which has hardwood panelling on the walls. I did an airborne mold test a month ago, and it came back with many varieties of mold. The owner bleached the room, and I completed another home mold test - same result. Could anyone give an idea to what kinds of mold are in this picture after 96hrs? I know it needs to be sent to a lab, but pending results I would like more information for the safety of our residents. Thank you!
