[Microbiology] methanosarcina cultivation

[David Dietz]

Hello,
does anyone know, if there is a methanosarcina-strain that grows on a 
synthetic medium with a sensible growth rate - without addition of 
vitamins or complex medium components.
I want to ween my M. mazei Goe1 to acetate from methanol, but up to now 
I was not successful. Did anyone of you observe similar problems and can 
you tell me, how you solved the problem?
That would be a great help!
David
