Kohlmeyer and Kohlmeyer (1979) have compiled 177 species of yeasts
which, were isolated from water sediment algae,,,, Animals and other organic
matter in the marine habitat. Of these only 26, species were regarded as obligate
marine, forms. The most important genera of true marine yeast are Metchnikowia
Kluyveromyces Rhodosporidium Candida,,,,,, Cryptococcus Rhodotorula And
Torulopsis.These studies established that marine yeasts do not belong to a
specific genus or group but are, distributed among a wide. Variety of well known
genera such as Candida Cryptococcus Debaryomyces Pichia,,,,,,, Hansenula
Rhodotorula Saccharomyces. Trichosporon and Torulopsis. The isolation
frequency of yeasts fall with depth and it was found that yeasts in the class
Ascomycetes. Candida (eg,.,, Debaryomyces Kluyveromyces Pichia and
Saccharomyces) are common in shallow waters whilst yeasts, belonging to
Basidiomycetes. ,,, (Cryptococcus Rhodosporidium Rhodotorula Sporobolomyces)
are common in deep waters. For example Rhodotorula has been. Isolated from a
depth, of 11 000 m Munn 2004 (,).
