Only supplementation of <i>Nannochloropsis</i> led to significant differences in enrichment by supplementation of the two forms, with the highest enrichment obtained with the HPH-disrupted form. This confirms the presence of a rigid cell wall for this species, which reduces the bioaccessibility of the n − 3 PUFA. The needed conversion reaction from EPA to DHA on the other hand did not seem to effect the enrichment, since the same n − 3 LC-PUFA enrichment was obtained with the supplementation of the DHA source <i>Isochrysis</i> and the EPA source <i>Nannochloropsis</i>, the last in HPH-disrupted form.Next to the microalgal species, fish oil was also supplemented to the diet of the laying hens. Fish oil resulted in a higher enrichment in comparison with the microalgal species, either non-disrupted or HPH-disrupted. This might suggest a difference in bioaccessibility of the n − 3 PUFA when added as oil or biomass.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The cell wall of autotrophic microalgae influences the enrichment of long chain omega-3 fatty acids in the egg","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":"n-3 LC-PUFA enrichment; HPH disruption; Nannochloropsis oculata;Isochrysis galbana; Fish oil; Eggs","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2022-05-10","DateCreate":"2016-10-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000375610000024","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.algal.2016.03.015"},"refs":null,"anarec":{"AnaID":280617,"PubliDate":2016,"Pagination":"209-215","XtraPublOfAnaID":null,"ISBN":null,"Volume":"16","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":247867,"SerRR":"Algal Research.
