Microalgal cell viability analysis using MTT assay and SYTOX ® Green method. a MTT result comparison of control (BG 11), 1% silicone oil nanoemulsion (1% SE) and 1% paraffin oil nanoemulsion (1% PE) in terms of optical density at 570 nm with corresponding vials showing purple formazan during the MTT Assay. Dark purple color represents greater cell viability. Errors bars are shown ± SD in MTT analysis. b SYTOX® Green-stained fluorescent micrographs of C. pyrenoidosa to differentiate live and dead cells: b control (BG 11), b2 1% silicone oil nanoemulsion, b3 1% paraffin oil nanoemulsion. Live cells appear red while dead cells appear green in color
