Isolation and identification of a halophilic and alkaliphilic microalgal strain.

ABSTRACT: Halophilic and alkaliphilic microalgal strain SAE1 was isolated from the saline-alkaline soil of Songnen Plain of Northeast China. Morphological observation revealed that SAE1 has a simple cellular structure, single cell, spherical, diameter of four to six μm, cell wall of about 0.22 μm thick, two chloroplasts and one nucleus. Analysis of the phylogenetic tree constructed by 18S sequence homology suggests that SAE1 is highly homologous to Nannochloris sp. BLD-15, with only four base substitutions in the homologous region. SAE1 was initially considered as Nannochloris sp. Analysis of the halophilic and alkaliphilic characteristics of SAE1 indicates that it can grow under one M NaHCO₃ and NaCl concentrations, with optimal growth under 400 mM NaHCO₃
