Disposal of polythene into waste water poses a serious problem as they get accumulated in the environment. Submerged polythene in waste water offers an ideal substratum for algae to colonize. The present paper highlights the biochemical composition of five cyanobacteria isolated from submerged polythene surface in domestic sewage water, Silchar town, Assam, (India). The carbohydrate, protein, lipid, vitamin C and pigments (Chla, carotenoids, phycobiliproteins) contents of five cyanobacterial species, Phormidium lucidum, Oscillatoria subbrevis, Lyngbya diguetii, Nostoc carneum, and Cylindrospermum muscicola isolated from submerged polythene surface were analysed. Maximum amount of total protein, carbohydrate and lipid content were found in Oscillatoria subbrevis and minimum in Cylindrospermum muscicola. Vitamin C was found to be highest in Oscillatoria subbrevis and Nostoc carneum and minimum in Cylindrospermum muscicola. The total phycobiliproteins was maximum in Oscillatoria subbrevis and minimum in Cylindrospermum muscicola. One-way analysis of variance (ANOVA) showed significant differences among the biochemical parameters of cyanobacteria isolated from polythene surface.
