Cyanobacterial diazotrophs play a significant role in environmental nitrogen economy despite their habitat either tropical or polar. However, the phenomenon by which it copes with temperature induced stress is poorly understood. Temperature response study of psychrophilic and mesophilic Nostoc strains explores their adaptive mechanisms. The selected psychrophilic and mesophilic strains were con...

Increasing wheat output while decreasing the usage of chemical fertilizers is a significant policy considering current economic conditions world going through. Thus, there necessity for encourage eco-friendly techniques to add benefits growth and productivity also reducing requisite. The study was carried out evaluate impact potent strain (Nostoc calcicola), its extract, compost tea solely or i...

Alkaline phosphatase (phosphomonoesterase i.e. PMEase) activity in heterocystous cyanobacteria Anabaena flos-aquae, Nostoc calcicola, Calothrix brevissima, Scytonema javanicum and Hapalosiphon intricatus is known to be temperature and pH dependent. Maximum level of enzyme activity was recorded at either 35 degrees C or 37.5 degrees C. Also, the cell bound phosphomonoesterase enzyme was shown to...
