摘要:The present investigation is aimed to understand how a bloom-forming cyanobacterium Microcystis aeruginosa adapts to changing climatic conditions. The cyanobacterium was exposed to stresses of UV-B (2 Wm−2) radiation and temperature (45 °C) for desired time interv...

摘要:Abstract(#br)In the present work, we describe a cheap, unexplored and simple procedure for the synthesis of zinc oxide nanoparticles (ZnONPs) using the cell extract of the cyanobacterium, Anabaena strain L31. An attempt was also made to conjugate synthesized ZnONPs with a UV...

摘要:Abstract(#br)Enzymatic and non-enzymatic defense strategies against ultraviolet-B radiation (UV-B, 280–315 nm) were studied in Anabaena doliolum and Anabaena strain L31, two of the most common strains of Indian cyanobacteria. Upon UV-B irradiation, both strains showed a 2–5-...

摘要:Abstract(#br)The effects of various irradiances of artificial UV-B (280–315 nm) in the presence or absence of visible light (photosynthetically active radiation) on growth, survival, 14 CO 2 uptake and ribulose 1,5-bisphosphate carboxylase (RuBISCO) activity were studied in ...

摘要:Abstract(#br)The shielding role of ferric iron (FeCl3) and certain cyanobacterial pigments (a brown‐colored pigment from Scytonema hofmanii culture filtrate and a pink extract from Nostoc spongiaeforme ) against UVB‐induced damage in the filamentous, nitrogen...

摘要:DNA is one of the prime molecules, and its stability is of utmost importance for proper functioning and existence of all living systems. Genotoxic chemicals and radiations exert adverse effects on genome stability. Ultraviolet radiation (UVR) (mainly UV-B: 280–315 nm) is one...
