Week 11

The other day I realized that there was some interesting white foam in one of my algal containers. I didn’t seem to be air bubbles from aeration. I am almost 100% certain that it was contamination. Fortunately, the presumed contaminated algae culture was an old culture that I wasn’t collecting any data from. Nevertheless, I was very concern. Honestly, I didn’t know what else to do besides adding more algae media.  I thought that maybe I could promote algae growth, and that would eliminate the contamination. I gave it a try, and guess what?? I checked on that same algal culture today, and there wasn’t any white foam!!

I don’t know, maybe it wasn’t contamination, but at least it’s gone. 

White foam is gone!!
