Abstract
Total nitrogen, chlorophyll-a, crude proteins,
lipids contents of filamentous, heterocystous soil cyanobacterial
species was estimated by standard methods. Cyanobacteria when grown under
laboratory conditions total nitrogen, chlorophyll-a, crude proteins, lipids
contents were obtained in the range of 1.52- 5.28%, 0.52- 5.67 μg gm-1,
9.50- 33% and 1.4- 19.2% respectively on fresh weight basis. Anabaena
circinalis, Nostoc punctiforme, Nostoc muscorum, Nostoc
carneum, Anabaena orientalis were found to be the dominant nitrogen
fixers encountered from the soils of the study area. However as far as
chlorophyll-a content was concerned not much variation was found in the tested
cyanobacterial species. Nostoc and Anabaena were found to be the
alternative sources of algal proteins and could be effectively used as protein
rich food. Almost all cyanobacterial species exhibited better lipids content
and therefore could be considered as good sources of biodisel. In most species
of Nostoc and Anabaena growth appeared to be correlated to
crude proteins and lipids contents. A general trend of more crude proteins
content than the lipids was observed in all the studied cyanobacterial forms.
