Resumo: | This research focuses on the oxylipins with eighteen carbons, compound derived of polyunsaturated fatty acids, produced by twenty-two species of freshwater algae, one cyanobacteria and three species of plants, with emphasis on green microalgae from the Chlorophyta and Charophyta phylum, and also species of the Selenastraceae family (Chlorophyta, Chlorophyceae, Sphaeropleales). The aim was detected, identified and quantified oxylipins derived from linoleic and linolenic acids produced by microorganisms using High-Performance Liquid Chromatography coupled tandem Mass Spectrometry technique. It was used microalgae from the Culture Collection of Freshwater Microalgae (CCMA-UFSCar), species already classified by classic and / or molecular taxonomy, as well as the species of plants for comparative purposes. For the experiments, the material came from the end of stationary phase. Once the compounds were identified by these techniques, it was tested the possibility of using profiles as diacritical characteristics in a chemotaxonomic approach for formation of hierarchical clusters. The pharmacological potential of these compounds was discussed since they present antibiotic and anti-inflammatory activities. Other possible commercial applications were approached since microalgae revealed their potential value as natural sources of hydroxy fatty acids. No oxylipin was exclusively observed to determinated organism that could represents as species indicator. This condition limits the use of oxylipins derived from C18 PUFAs in the taxonomy of the Selenastraceae family, but even so, these compounds provide complementary information for organisms that may be useful in their identification. There was universality regarding the presence of oxylipins analysed in all the taxonomic groups studied. The strains belonging to Chlorophyta division showed the highest total concentrations of oxylipins. Charophyta algae have a concentration of oxylipins dozens of times lower than Chlorophyta, and similar to concentrations found in plants, which may be related to the evolutionary proximity among plants and Charophyta. |

O objetivo principal foi detectar, identificar e quantificar as oxilipinas derivadas de ácidos linoléico e linolênico produzidas por esses organismos utilizando-se de técnicas de cromatografia líquida acoplada à espectrometria de massas. Utilizou-se cepas de microalgas da coleção de culturas do Laboratório de Ficologia da UFSCar, espécies já classificadas através da taxonomia clássica e/ou molecular, como também espécies de plantas para fins comparativos. Para os experimentos, a biomassa algal foi proveniente do final da fase estacionária. Uma vez identificados estes compostos pelas técnicas acima, testou-se a possibilidade de se utilizar estes perfis como características diacríticas em uma abordagem quimiotaxonômica para a formação de clusters hierárquicos. Também foi discutido o potencial farmacológico destes compostos por apresentarem atividades antibióticas e anti-inflamatórias. Outras possíveis aplicações comerciais também foram abordadas uma vez que as microalgas revelaram seu potencial valor como reservas naturais de hidroxi-ácidos. Não foi observada qualquer oxilipina exclusiva para determinado organismo que pudesse servir como um indicador de espécie. Esta condição limita a utilização de oxilipinas derivadas de PUFAs C18 na taxonomia da família Selenastraceae. Porém, mesmo assim, a quantidade e proporções das oxilipinas nos diversos perfis permitem que estes compostos forneçam informações complementares sobre os organismos que podem ser uteis na sua identificação. Houve universalidade quanto à presença das oxilipinas analisadas em todos os grupos taxonômicos estudados. As cepas pertencentes à divisão Chlorophyta apresentaram as maiores concentrações totais de oxilipinas. As algas Charophyta apresentaram concentrações de oxilipinas dezenas de vezes menor que Chlorophyta e semelhantes às concentrações encontradas em plantas, fato que pode estar relacionado à proximidade evolutiva entre plantas e Charophyta.OutraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)CNPQ: 141267/2014-3FAPESP: 2011/50054-4porUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNUFSCarOxilipinasChlorophytaCharophytaSelenastraceaeHidroxi-ácidosOxo-ácidosOxylipinsChlorophytaCharophytaSelenastraceaeHydroxy-acidsOxo-acidsCIENCIAS BIOLOGICAS::BIOQUIMICA::BIOQUIMICA DOS MICROORGANISMOSCIENCIAS BIOLOGICAS::BOTANICA::BOTANICA APLICADACIENCIAS BIOLOGICAS::BOTANICA::TAXONOMIA VEGETALCIENCIAS BIOLOGICAS::BOTANICACIENCIAS BIOLOGICAS::MICROBIOLOGIAOxilipinas no estudo da biodiversidade de microalgas de água doceOxylipins in the study of the biodiversity of freshwater microalgaeinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisOnline6006006b6727ce-acd7-4dc9-b8ab-698199cebaaeinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALTese INGRITT CAROLINE MOREIRA.pdfTese INGRITT CAROLINE MOREIRA.pdfapplication/pdf2137024https://repositorio.ufscar.br/bitstream/ufscar/10853/1/Tese%20INGRITT%20CAROLINE%20MOREIRA.pdf63efdff4c7afd9eeb4db6d7a1a0af110MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/10853/3/license.txtae0398b6f8b235e40ad82cba6c50031dMD53THUMBNAILTese INGRITT CAROLINE MOREIRA.pdf.jpgTese INGRITT CAROLINE MOREIRA.pdf.jpgIM Thumbnailimage/jpeg7735https://repositorio.ufscar.br/bitstream/ufscar/10853/4/Tese%20INGRITT%20CAROLINE%20MOREIRA.pdf.jpgcc7b9d6c59ef049551f593edaca481c4MD54ufscar/108532023-09-18 18:31:22.529oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:22Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

The aim was detected, identified and quantified oxylipins derived from linoleic and linolenic acids produced by microorganisms using High-Performance Liquid Chromatography coupled tandem Mass Spectrometry technique. It was used microalgae from the Culture Collection of Freshwater Microalgae (CCMA-UFSCar), species already classified by classic and / or molecular taxonomy, as well as the species of plants for comparative purposes. For the experiments, the material came from the end of stationary phase.
