To improve industrial strain of microalgae Arthrospira platensis (A. platensis), electron beam irradiation was performed. A. platensis cells were exposed to low energy (0.18 MeV, 0.3 mA) and high energy (0.2 MeV, 1.2 mA). Although the cell growth was decreased by high energy electron beam, lipid accumulation was exceedingly increased. In this study, mutants of A. platensis by high energy electron beam, EM240 and EM384, were isolated and characterized. After screening, mutants EM240 and EM384 having higher growth rate, cellular lipid content and phycocyanin pigment than parental strain were isolated. The increased active compounds of mutants, such as phycocyanin and lipids, revealed antioxidant and anticancer activities. It is the first reports on characterization of mutant strains of microalgae by electron beam irradiation. Microalgae species with improved growth rate and enhanced active compounds make the commercial process more feasible in industry. |
