| Description |
Molybdenum disulfide (MoS2) were widely utilized in environmental application, and were demonstrated low toxicity. MoS2 induce the reactive oxygen species (ROS) in freshwater environment and previously been considered were able to inhibit the growth of freshwater microalgae. Herein, we find MoS2 would remarkable enhance the growth of ocean algae in special concentration. Results showed that 50 μg/L of MoS2 would promote the growth rate of Dunaliella salina most significantly, and the protein content, carbohydrate content and lipid content were improved. Though the low concentration of MoS2 did not cause the cell morphological change, the antioxidant enzyme system was activated. The transcriptome results immaculately in line with the physiology phenomenon and uncover more detail of the molecular regulation mechanism. The MoS2 was able to improve the expression level of porphyrin and chlorophyll synthesis and energy metabolism related genes, to provide more energy and material for DNA replication. We proposed that the ROS dynamic regulation induce the positive function of special concentration of MoS2 in ocean microalgae and ocean algae Dunaliella salina possess diverse reaction to MoS2 from freshwater microalgae. |
