Summary dl-Ethionine-resistant mutants of Saccharomyces uvarum ATCC 26602 were found to overproduce exogenous l-methionine. dl-Ethionine-resistant mutant ER 108, carrying a mutation to chloramphenicol resistance was converted to petite form, and protoplasts obtained from it were fused with protoplasts from antibiotic-sensitive S. cerevisiae X2928 carrying six auxotrophies. The resulting fusants maintained four auxotrophies and were capable of overproducing l-methionine. These fusants were stable after ten passages on complete medium.
