PROPERTIES OF MICROALGAE OIL FROM THE SPECIES Chlorella protothecoides AND ITS ETHYLIC BIODIESEL

Abstract: Microalgae oil of the species Chlorella protothecoides was obtained via a donation of the Soley Biotechnology Institute (SOLEYBIO) and characterized according to the fatty acid profile. Ethylic biodiesel was prepared using methods adapted by the research group. Analysis of acidity, water content, and density and viscosity temperature dependence (293.15 K to 368.15 K) were performed for the oil and ethylic biodiesel. The biofuel was characterized in terms of its flash and cloud points, heat capacity and cetane … Show more

“…Estudos recentes revelaram que o cultivo de microalgas permite, também, incorporar o dióxido de carbono gerado em processos industriais no processo de fotossíntese e, assim, contribuir com o aumento do volume de biomassa das microalgas que, por sua vez, proverá mais volume de matéria-prima para extração do bio-óleo (SADATSHOJAEI et al, 2020). Essa inovação baseia-se na capacidade das microalgas autotróficas de consumir CO2 e produzir carboidratos, hidrogênio, proteínas e lipídios que podem ser posteriormente convertidos em biocombustíveis (BENEMANN et al, 2018).…”

“…No geral, as espécies de microalgas primárias usadas para a produção de biodiesel são dos gêneros Botryococcus (PRATHIMA e KARTHIKEYAN, 2017), Chlorella (CHI et al, 2019), Scenedesmus (PUGAZHENDHI et al, 2020), Chlamydomonas (SCRANTON et al, 2015, Dunaliella (PATEL et al, 2021) e Nannochloropsis (CANCELA et al, 2019). Algumas espécies de microalgas podem proporcionar elevados volumes de biocombustíveis direcionados como, por exemplo, a espécie Chlorella protothecoides, que é considerada uma matéria-prima excelente para a produção de biodiesel por poder acumular 55% de lipídios quando cultivada de forma heterotrófica perante limitação de nitrogênio (PARSAEIMEHR et al, 2017;BATISTA et al, 2018). Em contraste às biomassas lignocelulósicas, algumas microalgas podem acumular grandes quantidades de carboidratos na forma de amido ou celulose durante períodos de estresse ambiental extremo (NIPHADKAR et al, 2018;DAVE et al, 2019;DA MAIA et al, 2020).…”

“…The most common raw materials used for the production of biodiesel have been the basic vegetable oils, however, this presents multiple problems such as competition with the use of basic oils for nutritional purposes, the use of agricultural land, the use of pesticides and fertilizers necessary for crops, which in turn can leach out and contaminate the groundwater [2,4]. One potential alternative renewable raw material for the production of lipids to produce biodiesel are microalgae, which have the potential to overcome many limitations, they are capable of satisfying the world demand for transportation fuels [5] and they seem to be the only source able to completely displace diesel fossil [6]. Microalgae are photosynthetic microorganisms [7] with simple growth requirements that can produce around 80% lipid by dry mass weight, although the levels commonly obtained are 20-50% [8].…”

“…Unlike terrestrial crops, microalgae grow 10-50 times faster [5], which leads to higher biofuel volumes per hectare, for example the yield of microalgae oil (58,700 L ha −1) is about 31 times higher than that of jatropha (1892 L ha −1 ) [2]. For the cultivation of microalgae, there are different systems [9], which use light (as an energy source), water and carbon dioxide (as a carbon source) to cultivate microorganisms, these in turn perform photosynthesis to generate biomass and oxygen [10].…”

“…Third-generation biofuels that are produced from algae have gained popularity recently mainly due to 20-80% (dry weight) lipid accumulation in their cells (Singh et al, 2016), no competition with food, the high biomass production per hectare of cultivation and strong absorption of CO2 (Batista et al, 2018). It can generate biohydrogen, biomethane and bioethanol.…”
