Anyone want to help me pan for gold here?

I have prospected & mined for years. Your enclosed quote receives no further explanation in the article linked; I simply have no idea what it means to "prime through co-metabolism of added glucose".
On the other hand, the link does offer some temperature-for-charcoal-production info that is interesting in regard to our attempts to build solar trough ovens for charcoal production.
