Abstract

Purpose

Oxybenzone has received widespread attention owing to its extensive accumulation in the soil and adverse effects on plant growth. The aim of the study was to verify the potential of tobacco (Nicotiana tabacum) combined with the use of adenine and plant growth-promoting rhizobacteria (PGPR) (Methylophilus sp. strain FP-6) to enhance the efficiency of oxybenzone removal from the soil, and investigate the interaction between adenine and strain FP-6 that occurred during the phytoremediation process.

Methods

First, we determined whether the presence of adenine stimulated the growth and plant growth-promoting (PGP) traits of strain FP-6, which was isolated in our previous study and demonstrated considerable potential for the degradation of oxybenzone. The combined effects of strain FP-6 and adenine on the growth of tobacco and the efficiency of oxybenzone removal from the soil were then investigated. Furthermore, we evaluated the soil enzyme activities and microbial community composition in tobacco-growing soil containing oxybenzone.

Results

The adenine-FP6 amendment significantly improved photosynthetic efficiency and maintained the ion homeostasis of tobacco, which was destroyed by oxybenzone, thereby promoting the efficiency of phytoremediation of oxybenzone by tobacco (97.99%). Furthermore, a series of hydrolases involved in nutrient cycles and oxidoreductases with high reactivity to phenolic compounds in the soil were significantly up-regulated under this remediation strategy, which might be attributed to the increased relative abundance of some rhizosphere bacteria, such as Faecalibacterium, Agathobacter, and Sphingomonas.

Conclusion

The findings of this study provide an economical and ecological phytoremediation strategy for the efficient remediation of oxybenzone -contaminated soils.
