“…Zhu et al [40] optimized the growth of Chlorella zofingiensis in diluted piggery wastewater (initial COD, 1900 mg L −1 ). However, this study utilized undiluted piggery wastewater according to our previous studies [11,21], and the initial concentrations of COD (3100 mg L −1 ) and ammonia-nitrogen (770 mg L −1 ) were much higher than the usual tolerance range for microalgae. Fernández-Linare et al [41] achieved a higher removal rate at a pilot scale relative to this study, but it required 13 days of cultivation.…”

“…To treat raw piggery wastewater efficiently, a two-step (heterotrophic and mixotrophic) microalgal cultivation strategy was employed based on our previous study [21]. For the heterotrophic phase of wastewater treatment, pilot-scale PBRs were covered with aluminum foil to block natural sunlight, and then fresh raw piggery wastewater from Jacob Farms Corporation in South Chungcheong Province were transferred to the PBRs.…”

“…NH4Cl understanding in TAG induction in microalga cells can be applied to improve the microalgal lipid production process and environment bioremediation [20]. The ammonium biochemical mechanisms on microalgal growth and triglyceride production were initially investigated under photoautotrophic and mixotrophic conditions.…”

“…Os perfis lipídicos apontaram predominância na formação de ácido araquídico (C20:0) seguido do α-linolênico (C18:3). Pelos perfis, nota-se que grande parte dos ácidos graxos que compõem os lipídeos são ácidos graxos saturados, matéria-prima com potencial para geração de biodiesel dadas as seguintes propriedades que conferem ao combustível: alta estabilidade oxidativa, baixo retardo de ignição e menor potencial de emissão de NOx, poluente intensamente agressivo para a camada de ozônio (LEE et al, 2021).…”
