First record of marine phytoplankton, Picochlorum maculatum in the Southeastern coast of India

摘要

The marine phytoplankton Picochlorum maculatum (Chlorophyta:Trebouxiophyceae) is recorded for the first time in the Southeastern coast of India. In this study, marine phytoplankton were collected at Muthukkuda mangrove waters, Tamil Nadu, Southeast coast of India which was then isolated, purified and identified with rDNA sequencing. Recurrence component analysis of marine phytoplankton P. maculatum indicated that the peptides were composed of Beta structure, comprising alpha-helix, extended strand and random coil. The number of amino acids and chemical properties from the marine microalgae P. maculatum are calculated and having composition of Neutral (82.69%), Acidic (10.72%) and Basic (6.57%) amino acids. This species may be introduced by way of shipping and other transport mechanisms where organisms are inadvertently moved out of their home range, e.g., ballast water exchange.
