Methane from sugar

Dear PF Forum,
Can anyone help me?
I'd like to know what is the reaction that produces methane from sugar?
I believe it's reduction.
This is sugar oxydation:
C6H12O6 + 6O2 -> 6CO2 + 6H2O
What is the reaction to produce methane from glucose?
C6H12O6 + ??? -> CH4 + ???
And please if you would be so kind to include how many joules does this reaction produces/absorbs per mol or kg would be fine.
Thank you very much PF Forum, I do appreciate it.
I've googled it but I don't know the keyword to find the reaction.
All Google gives me is methanogenesis.

Thanks again

I'm not sure a direct and efficient pathway is likely to exist since sugar has only two Hs per C and methane needs four. Also consider that however sugar is broken up initially, you need to get rid of oxygen atoms. Oxygen atoms tend to hold on tight.

May be, you need some sort of catalysis in a form of enzymes or bacteria.
Methane is a by-product of sugar or food decomposition (could be from bacteria or fungus)
May be it will help you, seeing the process of decomposition in organic chemistry.
