Study shows brewer's yeast hybridizes in wasp gut

(Phys.org)—A team of researchers from Italy, Uruguay and Spain has found via lab study that common brewer's yeast not only mate in the guts of wasps, but interbreed with other yeast species, producing hybrids. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study and results and why they believe their findings could have implications for both environmentalists and manufactures of yeast based products.
