“…Among phytoplankton, the Bacillariophyta (diatoms) contributes at least 40% of the global annual primary productivity (Field et al 1998). These diatoms are ubiquitous occurrence in marine environment (Sunesen et al 2008). Genus Chaetoceros Ehrenberg is considered as most diverse and wide spread centric diatom (Cupp 1943, Rines 1999, Hasle & Syvertsen 1997.…”

Abstract:The present study investigated the morphology and taxonomy of marine centric diatom Chaetoceros lorenzianus from Karachi Harbor, Pakistan for the first time for the first time during the incident of Tasman Spirit Oil Spill (2003) in the area. Phytoplankton samples were collected from 5 different locations from the study area. Chaetoceros lorenzianus was found only at one station collected after Tasman Spirit Oil Spill. Moreover morphometric measurements of present record showed narrow range as compared to the records investigated by other workers.

The objective of this study was to identify morphological and molecular comparison of three marine Chaetoceros species using microscopic observations, sequence analysis of 18S rDNA, random amplified polymorphic DNA (RAPD-PCR) barcoding and nuclear magnetic resonance (NMR) spectroscopy. Chaetoceros were obtained from three different algae laboratories: Center of Excellence for Marine Biotechnology (CEMB), Chanthaburi Coastal Fisheries Research and Development (CHAN) and Institute of Marine Science, Burapha University (BIM). Genomic DNA for the RAPD-PCR analysis was extracted using the phenol–chloroform method, followed by 18S rDNA amplification. The blast results of 18S rDNA sequence confirmed the significantly matched to C. gracilis for Chaetoceros BIM and CHAN and C. muelleri for Chaetoceros CEMB(e-value = 0.0, identity = 99%). The RAPD-PCR results revealed differences in the three Chaetoceros isolates with polymorphisms between 30.43% and 60.00%, and Chaetoceros CEMB showed high polymorphic bands. Scanning electron microscopy revealed that Chaetoceros CEMB were larger and had larger setae compared to the other isolates ( P < 0.05). The results of the NMR characterization of metabolites were consistent with the results of the sequence and morphological analyses. The concentrations of several metabolites, including chlorophyll c 1 , chlorophyll a, Myo-inositol, fucoxanthin, astaxanthin, lutein and zeaxanthin, were lower in Chaetoceros CEMB than in Chaetoceros BIM and CHAN. However, high concentrations of fatty acids, such as oleic acid, linoleic acid, α-linolenic acid and arachidic acid, were observed in all isolates. Generally, the results of this study will aid future studies examining the diversity of Chaetoceros in various cultural environments.
