利用多层薄层贴壁光生物反应器室外培养螺旋藻的研究
Cultivation of Spirulina sp. in a photobioreactor attached with thin multilayers
摘要
Abstract
A new cultivation device attached with thin multilayers was designed for the outdoor cultivation of Spirulina sp. This study aimed to determine a suitable substratum for attachment and the light dilution rate for Spirulina sp. cultivation. The results showed that the biomass productivity of Spirulina sp. attached onto a superfine fiber towel (30–60 g/(m2·d)) was higher than that of Spirulina sp. attached onto a flocking cloth (10–40 g/m2/day). In addition, the cells of Spirulina sp. were cultivated in a device with different light dilution rates (2.5×, 5×, and 10×), and the highest biomass productivity (45–60 g/(m2·d)) after daily harvesting was observed at the dilution rate of 10×. The average biomass productivity of Spirulina sp. reached approximately 30.3 g/(m2·d) on the eighth day of cultivation, and the nutrients in the cells of Spirulina sp. were similar to those in cells cultivated in the conventional suspended medium. Thus, the results supported the idea of improving the production scale of the reactor.关键词
