A survey of two temperate estuaries (Rivers Tagus and Sado, Portugal) and the adjacent Atlantic Ocean revealed that the numbers of yeasts and yeast species decreased with increasing distance from the estuaries. The species common in both the estuaries and the adjacent ocean belonged to genera ( Debaryomyces and Rhodotorula ) that are widespread in the seas. The species exclusively or predominantly estuarine were Candida intermedia, C. lambica, C. silvicola, and Torulopsis candida. The maximum temperatures for growth of these species is about 10C lower than those of intestinal species ( Candida albicans, C. krusei, C. tropicalis, and Torulopsis glabrata ) previously found to occur in subtropical and tropical waters. The apparent role of water temperature as a selective factor for yeast growth is discussed.
