Abstract

Mangrove wetland is a unique ecosystem and has rich bioresources. In this article, the roots, stems, branches, leaves, barks, fruits, and flowers from 12 species of the mangrove plants and six species of the accompanying mangrove plants, seawater and sediments in mangrove ecosystems in China were used as sources for isolation of yeasts. A total of 269 yeasts strains were obtained from the samples. The results of routine identification and phylogenetic analysis showed that they belonged to 22 genera and 45 species. Of all the 269 strains, Candida spp. was predominant with the proportion of 44.61%, followed by Kluyveromyces spp. (8.55%), Pichia spp. (7.44%), Kodamaea ohmeri (5.58%), Issatchenkia spp. (4.83%) and Debaryomyces hansenii (4.46%). We also found that strains N02-2.3 and ST3-1Y3 belonged to the undescribed species of Pichia sp. and Trichosporon sp. respectively while strain HN-12 was not related to any known yeast strains. This means that different yeast strains of Candida spp. especially C. tropicalis were widely distributed in the mangrove ecosystems and may have an important role in the mangrove ecosystems. The results also showed that some of them may have potential applications.
