One point I noticed is the statement that the 'mud' was high in protien due to the bacteria. This would mean you are eating the dead bacteria bodies. Which is what you are eating when you read "xanthan gum" in any food product label.

The feces has been broken down, consumed in part at least, by the bacteria. The solid waste is most likely made up of other things besides butt biscuts, like toilet paper (YUM!) and garbage disposal scraps, and anything else that goes into the sewer. If you think about what we feed pigs, and we eat the pork, this would be like feeding our wastes to bacteria and eating them. Sans the fact that we don't feed pigs human toilet logs, recycled beer, and used toilet paper of course.

And then theres the urine and sweat recycling done on the space station.

It's all pretty sick sounding, but interesting at the same time.
