Hi David,

Im not sure if you are looking for yeast that can actually metabolise
methane, but there are definitely yeast that can utalise methanol as there
primary carbon source.
I know that a pichia pasturis strain has been used in our lab in the past as
an over expression system for correct folding of proteins. I think that
Invitrogen or perhaps strategene might have been the supplier. Also try the
nation strains collection.
Oh one final thing ..beware of the smell! These things are terible,
generally worse when they are killed!!
Good luck in your search.
