In the present study, Anabaena PCC550, Anabaena PCC574 and Cylindrospermum PCC518, Cylindrospermum PCC 567 have been subjected to 7 different inorganic culture media. In order to identify the best growth medium i.e.; optimized medium, the nutrient requirement of these two algae have been evaluated as prime requisite. The present investigation analyzed the growth of wet biomass of the four microalgae. In order to attain optimal growth of Anabaena and Cylindrospermum species, the 7 culture media employed in the current study were (i) BG11 medium (ii) Knoops medium (iii) Cyanophycean agar medium (iv) Modified Bristols medium (v) Prigsheims Medium (vi) Foggs Medium and (vii) Algal culture medium. Highest growth on 60th day was seen in Cylindrospermum PCC 518 (0.134mg/100ml), Anabaena PCC 574 (0123mg/100ml), Cylindrospermum PCC 567 (0.098mg/100ml), Anabaena PCC 550 (0.094mg/100ml) in Algal culture media which shows luxurient growth when compared to BG11, Foggs Media, Modified Bristols media, Knoops media. While, Prigsheims medium did not show any growth of Anabaena PCC550, Anabaena PCC574 and Cylindrospermum PCC518, Cylindrospermum PCC 567.

Western ghats (Biodiversity hotspot) of Kerala is abundant in cyanobacterial species diversity. The cyanobacterial genus Nostoc inhabits on natural rock surfaces, thus play an important role in terrestrial ecosystems by colonizing in new and unsettled ecological niches. The abiotic factors like temperature, pH, humidity, micro and macro nutrients contribute to the abundance of Nostoc spp. on the rock surface. Nostoc spp. act as a potential candidates for eco-friendly and sustainable agriculture. Even though, their substantial importance to the environment most of the Nostoc spp. are unexplored, especially from Western ghats region of Kerala. Hence, the present study investigated the diversity of epilithic Nostoc spp. from Western ghats regions of Kerala. A total of 25 epilithic Nostoc spp. were identified in this study. Among the 25 species, Nostoc tibeticum and N. indistinguindem are new records from India.

In the arid suburbs of Rawalpindi, we found as many as thirty species that belonged to seventeen genera and three major orders in the class Cyanophyceae. Based on species count, the orders Nostocales and Oscillatorales revealed more diverse (36.6%) as compared to the Chroococcales (16.6%). The genera Oscillatoria and Nostoc with 6 species (16.6%) were the most represented followed by Anabaena (10%), Chroococcus (10%), Phormidium, and Lyngbya (6.6% each). Several genera such as Calothrix, Parakomarekiella, Gloeothecca, Aphanotheca, Leptolyngbya, Synechococcus, Spirulina, Planktothrix, Westilliopsis and Compactonostoc with one species (33%) each remained least represented. Most interestingly, Nostoc pruniforme, Anabaena oryzae, Anabaena gelatinicola, Calothrix javanica, Westiellopsis prolifica, Parakomarekiella sesnandensi, Compactonostoc shennongjiaensis, Oscillatoria lutea, Planktothrix agardhii, and Leptolyngbya boryana are being reported for the first time as residents of biocrust soil substrate. Data collation on species distribution did not reveal any endemic species however recognized the occurrence of species in Pakistan that are not yet reported from Asia. Hence, the arid suburbs of Rawalpindi are rich in cyanophytes, exhibiting local variation with several new records. Most of these strains showed an in vitro culturing response, and therefore warrants probing their ecological functioning in the arid environments of the Asian continent.
