“…This is in accordance to most literature data, which have shown that high concentrations of PL and AMPL, relative to other lipid classes, are expected in microalgae [56,57] and Parrish and Wangersky [58] investigated lipid class production in several marine phytoplankton and reported these lipid classes as major constituents (~ 70-80%). Similarly, Chia [4] reported high percent contribution of PL and AMPL to total lipids in Chlorella sp. However, TG increase denotes stressing conditions, and according to [57], any TG content higher than 15% of the total lipids can imply nutrient stress, which can justify the increase in TG after 24 h exposure to the biochemical manipulation medium.…”

“…Several studies show lipid increase under nutrient stress [4,5,35,51,52]. Triacylglycerol (TG) accumulation was seen in Stephanodiscus minutulus when the cells were grown under Si, N or P limitation, while polar lipids decreased [53].…”

The aim of this study was to assess the feasibility of a 180 L photobioreactor in which a submerged ultrafiltration system was used to maintain continuous nutrient inflow without biomass loss from the culture. After exponential growth, approximately 15% of the total volume was removed and replaced with a modified medium to induce algal physiological responses as a biochemical manipulation procedure. In this system, Chlorella sorokiniana was kept under healthy conditions, according to protein: carbohydrate ratio. C. sorokiniana was grown exponentially for 4 days up to 8.9x10 6 cells mL -1 . The culture medium used for biochemical manipulation (72 h exposure) consisted of LC Oligo medium without nitrates or phosphates, and with 7x10 -7 molL -1 total copper. The results confirmed the effectiveness of the submerged membrane and showed that algae exposure to a stressing medium resulted in intracellular carbohydrate increase, thus protein: carbohydrate (P:C) ratios, and affected lipid class composition. This novel photobioreactor configuration has the potential to improve microalgal yields and/or specific intracellular constituents, inasmuch as biochemical manipulation of the biomass is facilitated and the continuous system is operated without biomass loss.

“…Considerando que as microalgas possuem grande quantidade de material mucilaginoso higroscópico constituído, principalmente, de polissacarídios (LOMBARDI et al, 2002), proteínas e lipídios (BERTOLDI et al, 2008;CHIA et al, 2013;ROCHA et al, 2014), sua incorporação na peletização de sementes pode contribuir para o desenvolvimento das plantas. Também fornecem materiais orgânicos biodegradáveis ao solo, como ocorre com o biofertilizante produzido por algas marinhas -sobretudo do gênero Lithothamnium, chamado de granulado bioclástico (VASCONCELOS, 2012).…”

Lima 3 RESUMO -Microalgas são consideradas organismos promissores com aplicações em diversas áreas, entre elas para a fixação de CO 2 , indústria alimentícia, cosmética e farmacêutica. A industrialização na produção desses organismos levará à geração de resíduos, cuja utilização é vista como contribuinte na redução de custos de produção. Nesta pesquisa, propôs-se o uso de microalgas como material cimentante para peletização de sementes de Bowdichia virgilioides Kunth, espécie nativa do Cerrado brasileiro. Biomassa das microalgas Selenastrum capricornutum e Chlorella sorokiniana foram obtidas a partir de cultivos semicontrolados em casa de vegetação. Nas microalgas, foi determinada a concentração de clorofila a, proteínas, carboidratos e lipídios totais, e a biomassa para peletização foi obtida com as células em fase estacionária de crescimento. Com relação às sementes, os tratamentos consistiram de semente nua, semente com gesso agrícola, semente com gesso agrícola e S.capricornutum ou com C. sorokiniana. Nessas, analisaram-se a emergência e desenvolvimento das plântulas e ocorrência de nódulos fixadores de nitrogênio. Os resultados indicaram que sementes com gesso e C. sorokiniana apresentaram porcentagem de emergência (76%) estatisticamente similar à obtida para sementes nuas (86%) e que foi mais elevada do que sementes peletizadas com gesso (60%) e com gesso e S. capricornutum (62%). A melhor porcentagem de emergência para C. sorokiniana em comparação com S. capricornutum pode estar relacionada ao maior conteúdo de lipídios (11,4 mgL -1 ) e carboidratos (25,0 mg L -1 ) em C. sorokiniana, em comparação com S. capricornutum (2,2 mg L -1 lipídios e 0,31 mg L -1 carboidratos). Parâmetros como tempo médio de emergência, comprimento e peso da parte aérea fresca e seca e radicular das plântulas de B. virgilioides foram similares para todos os tratamentos. Conclui-se que a biomassa de C. sorokiniana pode ter aplicação promissora como constituinte de material cimentante em peletização de sementes, apresentando resultados posistivos e similares à emergência de sementes nuas.Palavras-chave: Sucupira do Cerrado; Chlorella sorokiniana; Selenastrum capricornutum.

“…Limiting PO 4 3-, for example, may result in higher SAFA, MUFA and 18:2n-6 (linoleic acid) content [30]; Also, in a previous review of PUFA sources, authors highlighted Chlorella (C. minutissima) to be effective for arachidonic acid (AA) and EPA production, but not DHA [31].…”

Polyunsaturated fatty acids (PUFAs) comprise about 35-40% of the total lipid content from green algae Chlorella, reaching up to 24% linoleic acid and 27% α-linolenic acid in C. vulgaris. Also, microalgae nutrient composition may be modulated by changes in the culture medium, increasing fatty acid and microelement concentrations in the algae biomass. PUFAs, such as α-linolenic (n-3) and linoleic (n-6) acids, as well as its derivatives, are considered essential for dietary consumption, and their ability to regulate body chemistry has been recently explored in depth. A balanced fatty acid consumption is shown to counteract the negative effects of western diets, such as chronic inflammation and glucose intolerance. In this brief commentary, technological and practical uses of C. vulgaris are explored as means to improve dietary quality and, ultimately, human health.
