Unveiling the Diversity of Periphytic Cyanobacteria (Cyanophyceae) from Tropical Mangroves in Penang, Malaysia.

Cyanobacteria are one of the most important groups of photoautotrophic organisms, contributing to carbon and nitrogen fixation in mangroves worldwide. They also play an important role in soil retention and stabilisation and contribute to high plant productivity through their secretion of plant growth-promoting substances. However, their diversity and distribution in Malaysian mangrove ecosystems have yet to be studied in detail, despite Malaysia hosting a significant element of remaining mangroves globally. In a floristic survey conducted in Penang, peninsular Malaysia, 33 morphospecies of periphytic cyanobacteria were identified and described for the first time from a mangrove ecosystem in Malaysia. Sixteen genera, comprising Cyanobacteria adalah salah satu kumpulan organisma fotoautotropik yang paling penting yang menyumbang kepada penetapan karbon dan nitrogen dalam paya bakau di seluruh dunia. Mereka juga memainkan peranan yang penting dalam pengekalan dan penstabilan tanah dan menyumbang kepada produktiviti tumbuhan yang tinggi melalui rembesan bahan penggalak pertumbuhan tumbuhan. Walau bagaimanapun, kepelbagaian dan taburannya dalam ekosistem paya bakau Malaysia masih belum dikaji secara terperinci, walaupun Malaysia menjadi tuan rumah elemen penting bagi baki bakau di peringkat global. Dalam tinjauan floristik yang dijalankan di Pulau Pinang, Semenanjung Malaysia, 33 morfospesies cyanobacteria perifit telah dikenal pasti dan diterangkan buat kali pertama daripada ekosistem bakau di Malaysia. Sebanyak 16 genera, yang terdiri daripada
