A / -
Trying to make a flow chart for these bacteria and I'm have trouble. I'm not even sure if my test results are correct. It'd be much apreciated if someone could fill me in on the test results for these microbes (including checking what is already filled). It'd be even more appreciated if someone could actually do the flow chart since I have some drafts on paper but keep getting mixed up. Thanks in advance!!
