I attempted to do a yeast starter from a bottle I had. It was commercial beer. I started trying to build the colony by using some left over wort from a brew. It took 4-5 days to get any activity and started to see a couple of bubbles on top. I put it on a stir plate and cracked open the lid. I had a little yeast cake and closed the lid tight. Put it in the fridge. Now I have some test tubes to store the yeast in. I opened the jar and it was under pressure,Ike it had been fermenting. It is an ale. The top of the lid has what appears to be fungus, or mold on it. Did I get something bad or could it be ok? What am I looking for?
