I am culturing the big three Phyto strains (Tet, Nanno, and Iso). The problem I am having is that it appears my Iso culture is now contaminated with Nanno which has started taking over. My culture is a light lime green color and getting darker but has lost the distinctive yellow-gold color of more pure Iso.
To those of you who’s culture multiple strains alongside Nanno, how do you avoid contamination? It is possible that my starter culture came contaminated but it was a dark brown when I received it so it should have been pretty pure.
