摘要：
This study aimed at applying different intensities (30 and 60 mT) and exposure times (24 and 1 h d (1)) of MF to cultures of Chlorella kessleri and evaluated their effects on cell growth, proximate composition of biomass, pigment production and antioxidant activity. The condition of 60 mT for 1 h d (1) stimulated biomass concentration of 83.2% by comparison with control culture (CC). Besides stimulated 13.7% lipid synthesis, 38.9% chlorophyll a and 59.1% chlorophyll b, 25.0% total carotenoids and antioxidants up to 185.7%. Thus MF application is an excellent alternative to stimulate cell growth and high biotechnological interest biocompounds. (C) 2017 Elsevier Ltd. All rights reserved.
