Curious how Saccharomyces pastorianus (lager yeast) came into being, microbiologist Duccio Cavalieri and entomologist Stefano Turrillazzi had a hunch that the fungi were getting some matchmaking help from wasps.
Common ale yeast actually possesses resistant cell walls that makes it difficult to digest. New research now suggests that the principal reason our bodies are able to derive nutrients from yeast is with help from friendly bacteria that resides almost exclusively in our gut.
