“…For example, the relative abundance of genes for most functional pathways changed significantly at pH = 6.53. We suggested that the transition of functional pathway around neutral pH is important for nutrient cycling, supporting the previous finding that availability of inorganic P is controlled by soil pH and reaches a maximum near pH 6.5 (Wang et al, 2022).…”

“…We observed that α-diversity indices of microbial community in the PLA group was significantly higher compared to other groups at day 20 according to one-way ANOVA at p < 0.05 (Figure S8). The increase in microbial community richness may be due to the fact that PLA can be biodegraded as carbon sources to increase microbial community activity in sediments . Nevertheless, nonmetric multidimensional scaling (NMDS) plots based on the Bray–Curtis dissimilarity matrix of all samples showed a clear cluster of communities in microplastic-amended groups and control but changed across time (Figure S8D).…”

“…The increase in microbial community richness may be due to the fact that PLA can be biodegraded as carbon sources to increase microbial community activity in sediments. 42 Nevertheless, nonmetric multidimensional scaling (NMDS) plots based on the Bray− Curtis dissimilarity matrix of all samples showed a clear cluster of communities in microplastic-amended groups and control but changed across time (Figure S8D). Despite the significant differences observed in α-diversity indices at day 20, the addition of microplastics generally caused negligible differences between treatments.…”

“…Dactylosporangium genus has antimicrobial properties against Gram-Positive bacteria [ 68 ]. Ellin 6067 converts ammonia to nitrite, and it is tolerant to Cd pollution [ 69 ]. The above demonstrated temporal decrease of some genera with beneficial functions for the soil and plant growth in control but not in humic-supplemented soils and may account for some of the dry mass and plant morphometric long-term benefits.…”
