Next to the biochemical composition, the in vitro digestibility of carbohydrates, proteins, and lipids was studied for <i>Chlamydomonas nivalis</i>, <i>Porphyridium purpureum</i>, <i>Chlorella vulgaris</i>, <i>Nannochloropsis gaditana</i>, and <i>Scenedesmus</i> species biomass. These microalgae were also assessed for their ability to inhibit the angiotensin-1-converting enzyme (ACE-1, EC 3.4.15.1), which is known to play a role in the control of blood pressure in mammals. Large differences in organic matter solubility after digestion suggested that a cell disruption step is needed to unlock the majority of the nutrients from <i>N. gaditana</i> and <i>Scenedesmus</i> species biomass. Significant amounts of free glucose (16.4–25.5 g glucose/100 g dry algae) were detected after the digestion of <i>C. nivalis</i>, <i>P. purpureum</i>, and disrupted <i>Scenedesmus</i>. The fatty acid profiles showed major variations, with particularly high Ω-3 fatty acid levels found in <i>N. gaditana</i> (5.5 ± 0.5 g/100 g dry algae), while lipid digestibility ranged from 33.3 ± 6.5% (disrupted <i>N. gaditana</i>) to 67.1 ± 11.2% (<i>P. purpureum</i>). <i>C. vulgaris</i> and disrupted <i>N. gaditana</i> had the highest protein content (45–46% of dry matter), a nitrogen solubility after digestion of 65–71%, and the degree of protein hydrolysis was determined as 31% and 26%, respectively. Microalgae inhibited ACE-1 by 73.4–87.1% at physiologically relevant concentrations compared to a commercial control. These data can assist algae growers and processors in selecting the most suitable algae species for food or feed applications.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Nutritional profiling and preliminary bioactivity screening of five micro-algae strains cultivated in Northwest Europe","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"digestibility; bioactivity; micro-algae; nutritional profile; cell disruption","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-07-05","DateCreate":"2022-07-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000676211800001","VABBcode":null,"OpenAcc":1,"DOI":"10.3390/foods10071516"},"refs":null,"anarec":{"AnaID":353460,"PubliDate":2021,"Pagination":"1516","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":268336,"SerRR":"Foods.
