Interaction effects of different chemical forms of lanthanum, cerium, and fluorine on the taxonomic composition of soil microbial community

In our study, we hypothesize that the various interactions of different chemical forms of La, Ce, and F in the combined pollution soils have significant effects on the taxonomic composition of bacterial and fungal communities. Based on the pot experiments of four different combined pollution soils of two or three elements, i.e., La + Ce, Ce + F, La + F, and La + Ce + F, the high-throughput sequencing was performed on the soil samples with the goals to: (1) investigate the interaction effects of various chemical forms of these three elements on microbial community composition; (2) identify the sensitive and tolerant microbes under these interaction effects; and (3) detect the key driving factors (i.e., the different chemical forms of these elements) responsible for the sensitive and tolerant microbes.
