Abstract


Desertifilum, a filamentous cyanobacterial genus, was initially described from biological crusts in Thar crusts in India. In this study, we isolated a novel cyanobacterial strain (CHAB7200) from a alkaline pool in Zhejiang province, China. The strain showed an identical 16S rRNA gene sequence to Desertifilum tharense, but was distinctly different in cellular morphology, ultrastructure and ecology. In addition, the strain exhibited growth ability at different alkalinities during 4.5 ~ 54 g/L, and the optimum growth was shown at 1% salinity, indicating its stronger tolerance to wider range of alkalinities and salinities than D. tharense. Ecological niche is an important criterion used to separate and define cyanobacterial species. In this case, the strain was proposed as a novel cyanobacterial species, Desertifilum salkalinema. sp. nov.
