SYNONYMY OF CANDIDA-METHYLICA WITH CANDIDA-BOIDINII AND OF CANDIDA-METHANOLOPHAGA WITH CANDIDA-SUCCIPHILA

Some Candida species which can use methanol as a sole carbon source we re studied by performing chemotaxonomic tests; we determined the ubiqu inone systems of these organisms, their DNA base compositions, their e lectrophoretic karyotypes, and their DNA relatedness values. The type strains of Candida methanalophaga and Candida succiphila had similar D NA base compositions and exhibited 90% DNA relatedness. All Candida bo idinii and Candida methylica strains had DNA G+C contents of 30.8 to 3 1.0 mol%, and these organisms exhibited 87 to 101% DNA relatedness to the type strain of C. boidinii. We propose that C. methanolophaga and C. methylica should be synonyms of C. succiphila and C. boidinii, resp ectively.
