The aim of the present work was to evaluate the feasibility of microalgae cultivation using secondary treated domestic wastewater. Two Chlorella vulgaris strains (CICESE and UTEX) and an indigenous consortium, were cultivated on treated wastewater enriched with and without the fertilizer Bayfolan®. Biomass production for C. vulgaris UTEX, CICESE and the indigenous consortium grown in treated wastewater was 1.167±0.057, 1.575±0.434 and 1.125±0.250g/L, with a total lipid content of 25.70±1.24, 23.35±3.01and 20.54±1.23% dw, respectively. The fatty acids profiles were mainly composed of C16 and C18. Regardless of the media used, in all three strains unsaturated fatty acids were the main FAME (fatty acids methyl esters) accumulated in a range of 45-62%. An enrichment of treated wastewater with Bayfolan® significantly increased the production of biomass along with an increase in pigments and proteins of ten and threefold, respectively.
本研究旨在评估利用二级处理生活污水培养微藻的可行性。使用两种普通小球藻（CICESE 和 UTEX）和一个本土共生体，在添加和不添加肥料 Bayfolan®的富营养化处理废水中进行培养。在处理废水中生长的普通小球藻 UTEX、CICESE 和本土共生体的生物量产量分别为 1.167±0.057、1.575±0.434 和 1.125±0.250g/L，总脂含量分别为 25.70±1.24%、23.35±3.01%和 20.54±1.23%dw。脂肪酸谱主要由 C16 和 C18 组成。无论使用何种培养基，在所有三种菌株中，不饱和脂肪酸都是主要的 FAME（脂肪酸甲酯），积累范围在 45-62%之间。用 Bayfolan®富化处理废水显著提高了生物量的产量，并使色素和蛋白质分别增加了 10 倍和 3 倍。
