  1. You guys have made reference several times to the cellular energy system, the need to find a place to put the extra electrons, etc. Do you have a good reference to a writeup about this, for those of us whose last biology class was a very long time ago? It’s clear that this is a really important thing to understand.

    Is the effect of silver nanoparticles related to this? What determines which metals will be antimicrobial (copper, silver) and which won’t be (iron)?

    If this Desulfouibrio bacteria is a contributor to autism how can this be killed off and with what specifi antibiotican fo what period of time, would you also suggest molybdnum supplmentation?
