Effects of polyester microfibers (PMFs) and cadmium on lettuce (Lactuca sativa) and the rhizospheric microbial communities: A study involving physio-biochemical properties and metabolomic profiles

The rhizosphere is a microhabitat where there is an intense chemical dialogue between plants and microorganisms. The two coexist and develop synergistic actions, which can promote plants’ functions and productivity, but also their capacity to respond to stress conditions, including heavy metal (HM) contamination. If HMs are present in soils used for agriculture, there is a risk of metal uptake by edible plants with subsequent bioaccumulation in humans and animals and detrimental consequences for their health. Plant productivity can also be negatively affected. Many bacteria have defensive mechanisms for resisting heavy metals and, through various complex processes, can improve plant response to HM stress. Bacteria-plant synergic interactions in the rhizosphere, as a homeostatic ecosystem response to HM disturbance, are common in soil. However, this is hard to achieve in agroecosystems managed with traditional practices, because concentrating on maximizing crop yield does not make it possible to establish rhizosphere interactions. Improving knowledge of the complex interactions mediated by plant exudates and secondary metabolites can lead to nature-based solutions for plant health in HM contaminated soils. This paper reports the main ecotoxicological effects of HMs and the various compounds (including several secondary metabolites) produced by plant-microorganism holobionts for removing, immobilizing and containing toxic elements.

Anaerobic digestion (AD) is a biological process, encompasses the treatment and stabilization of complex organic matter to extract renewable biomethane fuel through microbial interaction in the digester. The main aim of the current study is to investigate the microbial community of anaerobic digestion sludge (ADS), collected at different periods from a mesophilic operating anaerobic digester. The core group of bacteria in ADS including Firmicutes, Bacteroidetes, and Proteobacteria represented more than 60% of the core bacterial community. In ADS (I), the supremacy of Cloacimonetes (18%) was also observed. In ADS (II), the dominance of Anaerobacter (8%) showed the effect of substrate composition on the microbial structure. However, 91% relative abundance of Firmicutes was observed in ADS (III). The hydrogenotrophic methanogens belonging to order Methanomicrobiales and Methanobacteriales exhibited dominance in all three ADSs (> 60%). No specific variations in the archaeal community might be attributed to the presence of beneficial bacterial species. This study provides all the detailed functional roles of microbes involved in AD which can further be used for additional environmental applications.
