A Polyphasic Characterisation of Tetradesmus almeriensis sp. nov. (Chlorophyta: Scenedesmaceae)

The microalga Tetradesmus almeriensis, previously known as Scenedesmus has been isolated and cultivated a highly productive, fast-growing strain natural source of different products commercial interest, including bioactive compounds such lutein. This produces up to 40 g·m−2·day−1 lutein under optimal conditions is recommendable for outdoor production in temperate warm climates, showing maximal performance at temperatures 35 °C with no photo-inhibition taking place irradiances greater than 1000 μE·m−2·s−1. Morphological molecular data allow its assignment the Chlorophycean genus Tetradesmus. new species can be distinguished from similar taxa due unique combination features that are seen light microscopy. We present herein robust comprehensive phylogenetic analysis T. together several additional Scenedesmaceae species, using maximum likelihood Bayesian approaches. Our results confirm almeriensis distinct consistently clustering other Scenedesmaceae.
