Six species of macroalgae belonging to the Chlorophyta, Phaeophyta, and Rhodophyta divisions were cultivated in a closed system with Guillard's f/2, Walne's, Provasoli Enriched Seawater (PES) medium, and seawater (control) for 6 weeks. The growth rate and parameters of the tested seaweeds showed that all used media enhanced the growth rate and chemical content as compared with other seaweeds cultivated in seawater without addition of any nutrients. There are significant differences in the effect of the used media on the seaweed composition at p = .01; PES is more effective than the f/2 and Walne's media. The results indicate that the cultivation technique of some macroalgae was an efficient tool for increasing the seaweeds' biomass and increasing their chemical compounds, calories, and energy under laboratory conditions.
六种分别属于绿藻门、褐藻门和红藻门的大型海藻，在封闭系统中，使用 Guillard 的 f/2 培养基、Walne 培养基、普洛瓦索利富硒海水（PES）培养基以及海水（对照）培养 6 周。受试海藻的生长速率和参数表明，与在未添加任何营养物质的海水中培养的其他海藻相比，所有使用的培养基均提高了生长速率和化学含量。在 p = 0.01 时，所用培养基对海藻成分的影响存在显著差异；PES 比 f/2 培养基和 Walne 培养基更有效。结果表明，在实验室条件下，某些大型海藻的培养技术是增加海藻生物量以及提高其化学化合物、卡路里和能量的有效工具。
