Microalgal phytoremediation is a promising bioremediation approach that can achieve significant resource recovery while effectively removing pollutants. However, the toxicity of some pollutants in wastewater often induces stress responses in microalgae, reducing their pollutant removal efficiency. Recently, phytohormones have been identified as a novel solution to reduce these stress responses, enhancing microalgae growth and improving their ability to remove various pollutants from wastewater. This advancement significantly boosts the efficiency and viability of microalgal phytoremediation. In this paper, the pathways and challenges related to microalgal phytoremediation were systematically analyzed. On this basis, the promoting effects of phytohormones on the removal of nutrients, heavy metals, and emerging contaminants by microalgae and the related mechanisms were discussed. Additionally, the review also discusses the optimal use strategy of phytohormones, the ecological risks that may be faced in the use of phytohormones, and the feasible strategies to control the use cost of phytohormones. The goal is to provide insights and guidance for future research on the application of phytohormones in microalgal phytoremediation.

This study reports the isolation and characterization of highly resistant bacterial and microalgal strains from an Egyptian wastewater treatment station to cyanide-containing compounds. The bacterial strain was identified as Bacillus licheniformis by 16S rRNA gene sequencing. The isolate removed up to 1 g L potassium cyanide, 3 g L benzonitrile, and 1 g L sodium salicylate when incubated as 10% v/v in MSM at 30 ℃.
