What is Evaluation of potent cyanobacteria species for UV-protecting compound synthesis using bicarbonate-based culture system about?
The present investigation evaluates the potential of three cyanobacteria species Anabaena cylindrica, Nostoc commune and Synechococcus BDUSM-13 for photo-protecting mycosporine-like amino acids (MAAs) synthesis using bicarbonate-based culture system. Current investigations witnessed noteworthy bicarbonate tolerance of all species (NaHCO 3 ; 0.5, 1 and 2 g L - 1 ) in terms of their growth rate, chlorophyll content, biomass productivity and carbon fixation ability. Among all strains, Synechococcus BDUSM-13 showed maximum surge in specific growth rate (i.e. 0.72 day -1 ) at 1 g L -1 , productivity (i.e. 0.92 ± 0.06 g day -1 L -1 ) and chlorophyll content (i.e. 0.09 g L -1 ) at 2 g day -1 L -1 . Synechococcus cells were also has the 0.48 g dw -1 carbon content with highest CO 2 fixation rate (i.e. 0.653 g.CO 2 mL -1 day -1 ) at 2 g L -1 . Though, they were not able to produce MAAs after long UV-B exposure (i.e. 24 and 48 h). A. cylindrica strain was the most competent species for the bicarbonate-based approach, produced UV-protecting iminomycosporine compound (i.e. shinorine, λ max at 334 ± 2 nm) along with carbon fixation (i.e. 0.49 g CO 2 mL -1 day -1 ) at 2 g L -1 NaHCO 3 .
