Infection?? Is yeast still usable?

[GrizBrew]

So, I made this table beer to propagate yeast for a Bier De Garde. I assume this is an infection. If you don't think so please say. If it is an infection, is there any chance that the yeast would still be usable? Thanks

Hate to tell you this, but it definitely looks like an infection. I would not use the yeast again - you'll just carry the infection over with it. Sorry

Yeah...I guess I really knew that, just didn't want to believe it

Thanks

I guess the bright side of all this is that I have an empty fermenter! And it was only a 3 gallon batch. I guess I will have to figure out a different yeast though. Luckily, BDG isn't too particular on it's yeast. Maybe another pack of Wyeast Bier De Garde and some Nottingham would do the trick

Double infection!! A small batch of parti gyled Dunkelweizen had a nasty floater too. I didn't see anything, smell anything or taste anything funky in the 5 gallon batch of Dunkelweizen , so I racked it to a secondary leaving the top layer fairly undisturbed. A touch under attenuated but better sweet than sorry

I had a well used plastic tube that may be the culprit. I tossed it along with some ugly airlocks. Hopefully this will take care of it. This is my first infection in over 30 batches. I suppose I was due. Pretty lame though. I guess I am shopping for some new plastic today...
