Di-(2-ethylhexyl) phthalate (DEHP) exposure significantly decreased soil nitrification through inhibiting ammonia-oxidizing bacteria and destabilizing their co-occurrence networks

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103682 - 103682

Di-(2-ethylhexyl) phthalate (DEHP) has increasingly accumulated in soils due to DEHP-containing plastic film been extensively used agriculture. However, the exposure of DEHP on calcareous soil nitrification potential, ammonia-oxidizing archaea (AOA) and bacteria (AOB) are poorly investigated. Here, an incubation experiment was established containing four treatments:(ⅰ) unfertilized blank control, (ⅱ) urea addition alone, (ⅲ) plus (10 mg kg-1), (ⅳ) (100 kg-1). The influences NH4+-N, NO3--N, potential rate (PNR), ammonia monooxygenase (AMO) activity, AOA AOB were analyzed. We found that 100 kg-1) lowered NO3--N treatments DEHP10 DEHP100, it significantly decreased PNR AMO activity. Also, reduced numbers gene copies, community's α-diversity. Moreover, destabilized co-occurrence network key module abundance, but its community not significant. Taken together, inhibited a through decreasing copies weakening community. Our findings provide novel insights into microbial mechanisms about detrimental effects pollution process soil.

Multiple Factors Jointly Lead to the Lower Soil Microbial Carbon Use Efficiency of Abies fanjingshanensis in a Typical Subtropical Forest in Southwest China

Forests, Journal Year: 2023, Volume and Issue: 14(9), P. 1716 - 1716

Abies fanjingshanensis trees are the only remaining species in a type of subtropical forest southwest China and imminent danger. Previous studies suggested that massive death was caused by unbalanced chemometrics nutrients soil. To best our knowledge, for first time, we evaluated microbial carbon use efficiency (CUE) rhizospheric topsoil subsoil A. fanjingshanensis, at high elevation, middle low elevation as well investigated their physicochemical indices, soil enzyme activities, bacteria, fungi, biomass. The results showed parameters (TP, SOC, AK, AP, MC, TN, NO3-N, NH4-N cation exchange capacity) were higher than those subsoil. Acidobacteria, Proteobacteria, Planctomycetes, Actinobacteria dominant phyla two layers. Candidatus_Koribacter main indicator positive correlation bacterial co-occurrence networks implied cooperation between bacteria four types, same phenomenon found fungi. A structural equation model confirmed pH most important factor affecting CUE We inferred microorganisms acidic environment forced to consume more energy maintain cellular pH, while less used growth. increased solubility some toxic metals affected microbes, resulting lower Our highlight values mainly CUE, may be another large numbers fanjingshanensis. Several measures must carried out improve department management, such adding appropriate biochar nitrogenous fertilizer.
