Cyanobacterial Diversity In Selected
Tropical And Polar Environments.
Masters thesis, Universiti Sains Malaysia.
Abstract
Cyanobacteria are the most ancient and widespread group of photosynthetic
prokaryotes and had a major role in the evolution of the plant kingdom and Earth’s
atmosphere. They are primary producers in a wide variety of habitats and are able to
thrive in harsh environments. This study explored the cyanobacterial communities in
sediment and soil samples collected from selected areas from Antarctic (Browning
Peninsula, Dee Island, Greenwich Island and Reeve Hill), Arctic (Kvartsitsletta and
Polish Polar Station) and Tropical (Air Terjun River, Air Itam River, Dondang River,
Jelutong River and Pinang River) regions, by identifying taxa via 16S rRNA gene
amplicon sequence data. 16S rRNA gene amplicons generated from 11 samples were
sequenced using illumina Miseq, with the targeted V3 and V4 regions yielding
approximately 1 million reads per sample. East Antarctica (Browning Peninsula and
Reeve Hill) recorded nine genera of cyanobacteria and west Antarctica (Dee Island
and Greenwich Island) recorded seven genera. The two Arctic sampling sites recorded
the lowest number of genera, five.
