“…We highlighted various correlations between PAH pollution and the proportions of some phyla or OTU abundance, but found no relationship with functional metabolic diversity, suggesting a limited impact of PAH on microbial community carbon-cycle related functions in our soils. Total and available PAH contents were both positively correlated to the proportions of Proteobacteria (mostly Gamma-Proteobacteria) and Nitrospirae phyla, even if in the literature the Nitrospirae phylum seemed to be negatively impacted by PAH content and bioavailability [79]. Proteobacteria and Gamma-Proteobacteria were previously found in greater proportions in pyrene-amended soil [80] and can be involved in PAH degradation [81].…”

The intensive industrial activities of the 20th century have left behind highly contaminated wasteland soils. It is well known that soil parameters and the presence of pollutants shape microbial communities. But in such industrial waste sites, the soil multi-contamination with organic (polycyclic aromatic hydrocarbons, PAH) and metallic (Zn, Pb, Cd) pollutants and long-term exposure may induce a selection pressure on microbial communities that may modify soil functioning. The aim of our study was to evaluate the impact of long-term multi-contamination and soil characteristics on bacterial taxonomic and functional diversity as related to the carbon cycle. We worked on 10 soils from northeast of France distributed into 3 groups (low anthropised controls, slag heaps, and settling ponds) based on their physico-chemical properties (texture, C, N) and pollution level. We assessed bacterial taxonomic diversity by 16S rDNA Illumina sequencing, and functional diversity using Biolog® and MicroResp™ microtiter plate tools. Although taxonomic diversity at the phylum level was not different among the soil groups, many OTUs were influenced by metal or PAH pollution, and by soil texture and total nitrogen content. Functional diversity was not influenced by PAH contamination while metal pollution selected microbial communities with reduced metabolic functional diversity but more tolerant to zinc. Limited microbial utilisation of carbon substrates in metal-polluted soils was mainly due to the nitrogen content. Based on these two observations, we hypothesised that reduced microbial activity and lower carbon-cycle-related functional diversity may have contributed to the accumulation of organic matter in the soils that exhibited the highest levels of metal pollution.

“…However, the petroleum-degrading bacteria gives better results than biochar alone during 60 days incubation, suggesting that the degrading bacteria could adapt to soil environment quickly and have a higher ability of petroleum degradation than biochar. 6,30 The relative abundance of n-alkanes (C 12-18 ) of oil is presented in Fig. 2a-e.…”
