Phylogenetic analyses on the biological crusts of several algae in the Taklimakan Desert

doi:10.11686/cyxb20140310

Abstract

Abstract: The unique biological property of desert algae comes from the extreme environment of the Taklimakan Desert in Xinjiang, but so far there are no related reports on the desert algae. To study the microalgae species of the Takilimakan Desert, 6 desert microalgae were isolated from sand samples using 96-well plate limited dilution and spread plate methods. Morphologically, 5 of the strains investigated were Chlorophyta (TLD2A1,TLD2B,TLD6B,TLD7A-2,TLD7B-5) while TLD5A1 was a Cyanobacterium. TLD2A1 and TLD2B showed a close relationship with Chlorellaceae, TLD2B and TLD7A-2 with Chlamydomonadaceae, and TLD7B-5 with Tetranephris brasiliensis of the Sphaeropleales. TLD5A1 and Nostoc clustered in a single clade, and the TLD5A1 strain was 97% similar to Nostoc ellipsosporum. This study determined the taxonomic status of the 6 strains of microalgae in the desert, providing a theoretical basis for future research of the Taklimakan Desert algae.
