Enhanced growth and lipid productivity by living Chlorella sorokiniana immobilized in Ca-alginate beads

Abstract The bottleneck for the production of biofuels from microalgae consists on costly harvesting processes and low lipid production, immobilization technology could play a part making more feasible. aim this study was to evaluate effect alginate growth productivity Chlorella sorokiniana , so far, main focus has been its use wastewater treatment nutrient removal effluents. cultured in both free immobilized forms under optimal autotrophic conditions. Microalgae were calcium beads generated by mixing algal cells with sodium solution, followed extrusion into CaCl 2 solution. results obtained showed that beads, enhanced achieved dry cell weight 1.4-fold higher than culture, light transmittance also increased 54.21 ± 2.48 mg l −1 d culture 82.22 8.48 culture. These demonstrate effectiveness promoting .
