Comparison of Growth Performance, Pigment Synthesis, and Esterase Activity of Synechococcus sp. HS01 and Limnothrix sp. KO01 in Response to Cadmium Toxicity.

Various studies have been conducted to understand the impact of environmental pollutants on cyanobacteria due to their abundant presence in aquatic and terrestrial environments, specific morphological and physiological characteristics, and high ecological flexibility in response to environmental changes. Here, the effect of different concentrations of cadmium on two native strains of cyanobacteria, namely Synechococcus sp. HS01 and Limnothrix sp.

Cadmium uptake capacity of an indigenous cyanobacterial strain, Nostoc entophytum ISC32: new insight into metal uptake in microgravity-simulating conditions.

Among nine cyanobacterial strains isolated from oil-contaminated regions in southern Iran, an isolate with maximum cadmium uptake capacity was selected and identified on the basis of analysis of morphological criteria and 16S rRNA gene sequence similarity as Nostoc entophytum (with 99% similarity). The isolate was tentatively designated N. entophytum ISC32.

Lipid production and mixotrophic growth features of cyanobacterial strains isolated from various aquatic sites.

The present study was conducted to determine the potential of five cyanobacteria strains isolated from aquatic zones to induce lipid production. The phylogenetic affiliation of the isolates was determined by 16S rRNA gene sequencing. Amongst the isolates, an efficient cyanobacterium, Synechococcus sp.
