Recently, BUCK and GREENFIELD have reported that 3 strains of yeast from sea water or a deep-sea core also take part in the precipitation of calcium carbonate. In this report, taxonomic investigation of 32 strains of yeasts from sea water taking part in the precipitation of calcium carbonate were made according to the method of LODDER and KREGER-VAN RIJ. Twenty nine strains of the yeasts belonged to the 3 genera, Rhodotorula, Candida or Debaryomyces as a result of the taxonomic exami-nation based on the various morphological, biochemical and biological properties. Fur-thermore, the 24 strains of the genus Rhodotorula were identifiedas R.mucilaginosa (17 strains), R. glutinis (5 strains), R. minuta (1 strain) or R. rubra (1 strain) and the 4 strains of the genus Candida were C. intermedia (2 strains), C. albicans (1 strain) or C. parapsilosis (1 strain) respectively. One strain of the genus Debaryomyces was identified as D. nicotianae and the 3 strains remaining may be recognized as an imperfect type of Saccharomyces fructuum lacking the ability for ascospore formation.
