Phycoerythrin (PE) is a compound with strong potential for both basic research and industrial applications, but short supply and high prices have so far hindered its development. One common problem is a shortage of biomass for extraction. The aim of the present study was to determine a cultivation strategy (optimizing temperature, irradiance, photoperiod, and light quality) to produce greater biomass and higher PE concentrations in the alga Colaconema sp. We found that an optimized culture process could increase algae growth 7-9 fold while allowing extraction of 9-10 mg g total phycobiliproteins, containing 60%-65% PE. Low energy costs make this approach economically feasible and competitive when compared with existing methods. Our results suggest an improved strategy for the large-scale production of PE and offer valuable applications in the algae industry.
藻红蛋白（PE）具有很强的基础研究和工业应用潜力，但供应短缺和价格高昂一直阻碍着它的发展。一个常见的问题是缺乏用于提取的生物质。本研究旨在确定一种培养策略（优化温度、光照度、光周期和光质），以生产更多的生物质和更高浓度的藻类 Colaconema sp. 的 PE。我们发现，优化的培养过程可以使藻类生长增加 7-9 倍，同时可以提取 9-10mg g 总藻胆蛋白，其中含有 60%-65%的 PE。低能源成本使这种方法在经济上可行，并具有竞争力，与现有的方法相比。我们的研究结果为大规模生产 PE 提供了一种改进的策略，并为藻类产业提供了有价值的应用。
