Studies on developments of microspheres from macroalgal clones and cultivations in airlift photobioreactor
大型海藻无性系微球体构建和反应器培养研究

Three macroalgal clones of Grateloupia filicina, Polysiphonia urceolata and Ulva pertusa, respectively, were obtained by the totipotency of marine algae. From them, three types of algal microspheres suitable for cultivation in a 10-L airlift photobioreactor were developed, which were flossy, netty and fascicular, respectively. The tufted microspheres of U. pertusa were cultivated in the photobioreactor to the biomass density of 5.81 g/L FW L, with the maximum growth rate of 0.36 g/(L?d)FW and specific growth rate of 0.103 d?1. The technology of high-density culture of macroalgae in photobioreactor will have wide applications, including seeding, mass cultivation, integrate-aquaculture, and manufacture of bioactive products.
