Efficient lipid synthesis of Chlorella pyrenoidosa<\/em> promoted under heavy metals from electric arc furnace slag<\/strong><\/p>\n

Recently, Dr Yi-Tong Wang (female, Associate Professor, College of Metallurgy and Energy, North China University of Science and Technology) and Prof. Zhen Fang<\/strong> published an article in Journal of Cleaner Production (IF: 11.072, Q1) about using efficient lipid synthesis of Chlorella pyrenoidosa<\/em> microalgae promoted under heavy metals from electric arc furnace slag.<\/p>\n

Electric arc furnace slag is highly productive and rich in elements, which can be used as a nutrient source for microalgae. The study investigated the regulation of growth and lipid synthesis of Chlorella pyrenoidosa<\/em> in electric arc furnace slag leaching solution, and citric acid electric arc furnace slag co-leaching solution, to achieve lipid production while treating metallurgical solid waste. The results showed that the highest biomass and lipid contents were 0.23 g\/L and 45.89 wt%, respectively, when BG11 was added to the electric arc furnace slag leaching solution. The highest biomass and lipid contents were 0.25 g\/L and 33.37 wt%, respectively, for the addition of citric acid electric arc furnace slag leaching solution at BG11. Various metal ions in the electric arc furnace slag leaching solution increased the biomass lipid content by modulating acetyl-CoA carboxylase, malic enzyme, and phosphoenolpyruvate carboxylase activities. This study helps to solve the problem of the high cost of microalgae culture and metallurgical solid waste treatment while generating lipids and provides a new green pathway for the commercialization of microalgae.<\/p>\n

High lipid content (45.89 wt%) was obtained by adding EAFS leaching solution into BG11. High biomass content (0.44 g\/L) was achieved by citric acid assisting EAFS leaching. \u5728BG11\u4e2d\u52a0\u5165EAFS\u6d78\u51fa\u6db2\uff0c\u83b7\u5f97\u4e86\u8f83\u9ad8\u7684\u8102\u8d28\u542b\u91cf(45.89 wt%)\u3002\u67e0\u6aac\u9178\u8f85\u52a9EAFS\u6d78\u51fa\u53ef\u83b7\u5f97\u8f83\u9ad8\u7684\u751f\u7269\u8d28\u542b\u91cf(0.44 g\/L)\u3002<\/p>\n
