“…Additional research indicated that the dry biomass of Chlorella zofingiensis cultured in media that was recycled three times was approximately 80% less than that cultured in fresh media [13]. Compared with the results of earlier studies, recent studies have demonstrated that the reuse of culture media had positive effects on microalgal growth [14][15][16][17]. Kim et al [14] reported that flocculated medium with coagulants and bioflocculants showed a b8% decrease in the growth yield in subsequent algal cultivations, which might have been related to a reduction in the nutrients in the flocculated medium.…”

In this paper, we describe the synthesis of magnesium aminoclay-iron oxide (MgAC-Fe 3 O 4) hybrid composites for microalgae-harvesting application. MgAC-templated Fe 3 O 4 nanoparticles (NPs) were synthesized in different ratios of MgAC and Fe 3 O 4 NPs. The uniform distribution of Fe 3 O 4 NPs in the MgAC matrix was confirmed by transmission electron microscopy (TEM). According to obtained X-ray diffraction (XRD) patterns, increased MgAC loading leads to decreased intensity of the composites' (311) plane of Fe 3 O 4 NPs. For harvesting of Chlorella sp. KR-1, Scenedesmus obliquus and mixed microalgae (Chlorella sp. KR-1/ Scenedesmus obliquus), the optimal pH was 4.0. At higher pHs, the microalgae-harvesting efficiencies fell. Sample #1, which had the highest MgAC concentration, showed the most stability: the harvesting efficiencies for Chlorella sp. KR-1, Scenedesmus obliquus, and mixed microalgae were reduced only to~50% at pH = 10.0. The electrostatic interaction between MgAC and the Fe 3 O 4 NPs in the hybrid samples by microalgae, as confirmed by zeta potential measurements, were attributed to the harvesting mechanisms. Moreover, the zeta potentials of the MgAC-Fe 3 O 4 hybrid composites were reduced as pH was increased, thus diminishing the microalgae-harvesting efficiencies.

“…As microalgas acumulam lipídios em sua composição, que são extraídos e posteriormente esterificados, produzindo biodiesel (Francisco et al, 2014). Recentemente, a microalga Chlorella vulgaris vem sendo altamente estudada para a produção de biodiesel (Al-lwayzy et al, 2014;Farooq et al, 2015;Josephine et al, 2015), assim como a microalga Desmodesmus sp. (Rios et al, 2015;Ji et al, 2015).…”

RESUMO -Neste trabalho, estudou-se o crescimento de três diferentes cepas de microalgas: Chlorella vulgaris, Desmodesmus sp e Desmodesmus brasiliensis, visando a produção de biodiesel. As microalgas foram crescidas em cultivo autotrófico, no meio de cultivo BG-11. As taxas de crescimento destas microalgas foram calculadas e comparadas entre estas três cepas. Quanto maior for a taxa de crescimento da microalga, mais interessante é seu uso na produção de biodiesel, e mais viável se torna o processo de produção deste biocombustível. As microalgas que apresentaram maiores taxas de crescimento e menores tempo de duplicação foram Desmodesmus sp e Chlorella vulgaris.
