“…Bacteria living in the rhizosphere are relevant not only because they are responsible for denitrification but also because they can promote plant growth via phosphate solubilization, releasing plant hormones, producing some enzymes like 1-aminocyclopropane-1-carboxylate deaminase or acting as biocontrol agents (Glick 1995;Lingua et al 2008b). Bacteria acting in this way are indicated as plant growthpromoting rhizobacteria and help plants to better respond to biotic and abiotic stresses.…”

High nitrogen concentration in wastewaters requires treatments to prevent the risks of eutrophication in rivers, lakes and coastal waters. The use of constructed wetlands is one of the possible approaches to lower nitrate concentration in wastewaters. Beyond supporting the growth of the bacteria operating denitrification, plants can directly take up nitrogen. Since plant roots interact with a number of soil microorganisms, in the present work we report the monitoring of nitrate concentration in macrocosms with four different levels of added nitrate (0, 30, 60 and 90 mg l(-1)), using Phragmites australis, inoculated with bacteria or arbuscular mycorrhizal fungi, to assess whether the use of such inocula could improve wastewater denitrification. Higher potassium nitrate concentration increased plant growth and inoculation with arbuscular mycorrhizal fungi or bacteria resulted in larger plants with more developed root systems. In the case of plants inoculated with arbuscular mycorrhizal fungi, a faster decrease of nitrate concentration was observed, while the N%/C% ratio of the plants of the different treatments remained similar. At 90 mg l(-1) of added nitrate, only mycorrhizal plants were able to decrease nitrate concentration to the limits prescribed by the Italian law. These data suggest that mycorrhizal and microbial inoculation can be an additional tool to improve the efficiency of denitrification in the treatment of wastewaters via constructed wetlands.

“…Meyer and Linderman [35] reported that Glomus and Pseudomonas dual inoculation enhanced root colonization. Thus, the interaction between Pseudomonads and AMF has many attentions [36] [37]. Further research is required to identify possible mechanisms mediating the reciprocal promotion of colonization by strains of AMF and Pseudomonads.…”

“…Bioaugmentation can also be performed by adding bacteria that directly or indirectly interact with plants: as previously reported, specific bacterial strains can promote symbiosis between plant roots and AMF [22,23]. Moreover, selected rhizobacteria can degrade total petroleum hydrocarbon effluent [24], organic chemicals [25], heavy metals [26], and contribute to nitrification [27] and denitrification [28].…”

Wastewaters generated by the pyrolytic process require treatments to reduce the risks of contamination in rivers, lakes, and coastal waters. Utilizing constructed wetlands is one of the possible approaches according to a Circular Economy System. Plant Growth-Promoting Bacteria (PGPB) and Arbuscular Mycorrhizal Fungi (AMF) can improve plant growth and enhance the bioremediation of wastewater. Two experiments were set up: in the first, a pilot mesocosm was designed to evaluate the effects of a consortium of AM fungi and a PGPB strain on Phragmites australis. After 60 days, the highest plant growth was obtained after inoculation with the combination of microorganisms. In the second experiment, a constructed wetland was built to remediate wastewaters from gasification plant. The plants were efficient in scavenging biological oxygen demand (BOD5), chemical oxygen demand (COD), total fat and oils, hydrocarbons, phenols, aldehydes, surfactants, fluorides, sulfites, sulfates, nitrate, and phosphorus. These data suggest that inoculation of P. australis with AMF and PGPB strains significantly improve the depuration process of wastewaters from gasification plants via constructed wetlands.
