However, most microalgae commercially cultivated are difficult to grow in colder climates. To overcome this problem one could cultivate cold tolerant algae. One such alga is the red marine alga <i>Porphyridium purpureum</i>. It is currently often cultivated in bag systems in limited volumes. In this study we cultivated <i>P. purpureum</i> at pilot-scale in horizontal tubular reactors in a greenhouse. <i>P. purpureum</i> was grown in batch mode in a total volume of either 350, 500, 1000 or 1500 L. A total of 28 batches, spread over two years, were cultivated reaching a maximum dry weight of 1.94&nbsp;g L<sup>−1</sup>. The growth was continuously monitored to calculate the productivities and growth rates. The P and N concentrations were measured frequently during four batches to calculate the P and N usage per gram biomass. To calculate CO<sub>2</sub> fixation efficiencies the total CO<sub>2</sub> consumption was monitored during 6 of the 28 batches. A maximum productivity and growth rate of respectively 0.195&nbsp;g L<sup>−1</sup>&nbsp;day<sup>−1</sup> and 0.233&nbsp;day<sup>−1</sup> were achieved while the P and N usage varied from 3.2–6.19 and 14.5–36.6&nbsp;mg&nbsp;g<sup>−1</sup> biomass for P and N, respectively. Growth was supported between 10&nbsp;°C and 30&nbsp;°C, while temperatures above 34—35&nbsp;°C proved to be detrimental. The CO<sub>2</sub> efficiencies differed among the 6 tested periods with the highest utilization efficiency being 13.5% and the lowest a mere 1.5%. Further large-scale, continuous, tests would be needed to fully optimize the cultivation of <i>P. purpureum</i> in larger volumes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Pilot-scale cultivation of the red alga <i>Porphyridium purpureum</i> over a two-year period in a greenhouse","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:32:37.757444","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Biomass production;Greenhouse;Microalgae;CO2-utilization;Porphyridium cruentum;Rhodophyta;FATTY-ACID-COMPOSITION;MICROALGAL CULTURES;WASTE-WATER;PHOTOSYNTHETIC EFFICIENCY;SEMICONTINUOUS CULTURE;OUTDOOR CULTIVATION;CLOSED SYSTEM;MASS-CULTURES;LIGHT;BIOMASS","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2023-10-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001039714200001","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s10811-023-03045-5"},"refs":null,"anarec":{"AnaID":367787,"PubliDate":2023,"Pagination":"2095-2109","XtraPublOfAnaID":null,"ISBN":null,"Volume":"35","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43025,"SerRR":"Journal of Applied Phycology.
