Abstract

lnformation on marine yeasts and their significance in polluted waters is scarce. In this paper we report the results of isolations of yeasts and molds found in marine waters from the Mar Menor (Southeastern Spain) and the mouth of the Segura river. Compositional modifications of various culture media and a critica1 evaluation of the results obtained are also presented. Mold colonies are significantly reduced in the modified media so that direct yeast counting becomes improved. Yeast counts, including red species, have been significantly higher in sediments as compared to free waters. Candida albicans was detected in relatively high numbers in the most polluted sites. The survival ability in natural waters of two yeasts, C. utilis and C. albicans was investigated. The results show that both yeasts present a high death rate in marine and brackish waters. only 1-0'01% remaining viable after 25 days in sea water.
