A novel strategy to promote microalgal growth and lipid productivity by supplementation of lignin related phenolic elicitors

An environment-friendly and cost-effective approach to improving lipid productivity without sacrificing microalgal growth was established. Syringic acid (SA) and p-coumaric acid (p-CA) are two major lignin hydrolysates, widely distributed in the wastewater from downstream industries of lignin. In th...
