Unusual occurrence of non carotenogenic strains of <i>Dunaliella bardawil</i> and<i> Dunaliella parva</i> in India

Abstract

Identification of green algal genus Dunaliella by conventional method is hard target since the strains vary morphologically and physiologically with conditions of growth. In this study, a total of nine different isolates of Dunaliella isolated from the salt pans of Tamil Nadu, India, were identified based on their morphology and cultural characteristics. In addition, the isolates were subjected to molecular identification using genus specific and species specific primers which distinguished the discrepancy in the conventional identification. This study evidently reported the first occurrence of non carotenogenic strains (a new variety) of D. bardawil and D. parva in India.
