Abstract The seaweeds Hypnea spp have been used as a direct human food, for carrageenan extraction, and exploitation of chemical compounds of interest. Nevertheless, its culture is still undeveloped because of difficulties in managing the epiphytic habit. Therefore, this study focuses on obtaining a suitable substrate for Hypnea pseudomusciformis settling and developing associated to a simple and efficient system to produce this red alga in tropical coastal regions of South Atlantic. We developed a substrate comprised of a 1 cm diameter polypropylene cable with 60 cm length, which was totally shredded. This structure allows that the epiphytic algae grow settled on the substrates and not only appended to it. A modular long-line structure comprised of 1 m polypropylene braided cables with two substrates spaced 30 cm each. Testing the prototype in a seaweed small-farm resulted in a growth rate of 5.66 % day−1 and a productivity of 0.64 kg m−1 in 45 days. This simple patented technology may base used the development of the culture of H. pseudomusciformis in familiar or industrial scales.

一种生产热带附生藻类 Hypnea pseudomusciformis 的简单基质

摘要 海藻 Hypnea spp 已被用作人类的直接食物，用于提取角叉菜胶和开发感兴趣的化合物。尽管如此，由于难以管理附生习性，其文化仍未得到发展。因此，本研究的重点是获得适合 Hypnea pseudomusciformis 沉降和发育的基质，该基质与在南大西洋热带沿海地区生产这种红藻的简单有效系统相关。我们开发了一种由直径为 1 厘米、长度为 60 厘米的聚丙烯电缆组成的基材，该电缆被完全切碎。这种结构允许附生藻类生长在基质上，而不仅仅是附着在基质上。一种模块化长线结构，由 1 m 聚丙烯编织电缆组成，其中两个基板的间距为 30 cm。在海藻小型农场中测试原型导致第 1 天的增长率为 5.66 %，45 天的生产率为 0.64 kg m-1。这种简单的专利技术可用于以熟悉的或工业规模的 H. pseudomusciformis 培养物的开发。
