The columns are definitely growing...stuff (ewww....too cool!) It appears that the control is in the lead for stratification, but then I'm a geologist in the making, what would I know about stratifying layers of microbial growth? To restate that, it appears that the control column has the greatest growth of green micro organisms. The layers may be obscured by the prolific growth. A better visual of the layering or stratification can be seen in the 4% saline column; much less growth of the brightly colored, happy looking bacteria though. As stated, this post is behind the times so may be redundant with another post, (apologies again.)
The columns (10/12/15)
Control, window side
4% saline, window side
8% saline, window side (sensing a pattern here?)
12% saline, again from the window side.
Top view of our protein shakes...ewww, just kidding.
