Abstract:
Cyanobacteriaor blue green algae is said to be ubiquitous,as it can live in marine, freshwater, brackish water and even hot spring. Bloom of cyanobacteria is associated with biotoxin risks in water bodies and consequently will affect the food web via bioaccumulation and biomagnificacion. In contrast, some of the non-toxic cyanobacteriaare cultured, processed and sold as supplementary food product, available in shops globally. This preliminary study assessed and documented cyanobacteria composition in two rivers, namely Sungai Semadang and Sungai Bengoh, Padawan, Sarawak. In total, there were 38 genera found with 10 genera listed as potential toxin producers. The common genera found in both rivers were Lyngbya, Oscillatoria, Stigonema and Spirulina. Sorensen’s Quotient of Similarity (%) value ranged from 21.4 to 83.7, indicating that there were some degrees of cyanobacteria similarity in both rivers.
