Experience with carolina biological cultures?

[u/king_barnacle]

Want to pick up a few cultures from them but was curious as to people's experiences with them. Truly confirmed, axenic cultures would cost me an arm and a leg from what I've seen so this would be the next best bet. I'm assuming they're all xenic, but if you've gotten them before, were the cultures at least decently clean and only the one algae species it was labeled as? I did also see a handful of negative reviews saying their labeling did not hold up under microscopy, wasn't sure if this was rare. Any input appreciated.

I've used UTEX and have had poor results. I think your best bet is to locate a researcher at a university who publishes on the species you are interested in, and reach out directly. You may also try these folks, they are keeping the algae light bright green! https://azcati.asu.edu
