“…Thus, the tetracycline was selected, due to its potential to reach soil and the aquatic environment [38][39][40][41][42]. Tetracycline residues were commonly detected on the soil [43][44][45][46], sediments [47][48][49][50], surface water [51][52][53], in the groundwater [54][55][56][57], wastewater [58][59][60][61][62][63].…”

The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa ) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.

“…The observed effect of SMZ could be explained by the selection of antibiotic-resistant bacteria. Indeed, persistence of resistant bacteria and contamination by antibiotics could be positively linked [27]. For instance, we showed in a previous study that the invasion of SMZ-resistant bacteria in soil can be favored in the presence of the antibiotic [28].…”

“…Since antibiotics are used on livestock [25], bacteria from animal tracts, which compose the manure community, may be more antibiotic-tolerant than non-antibiotic-exposed soil bacteria [26]. Indeed manure contains more antibiotic-resistant bacteria than soils [17,27]. Consequently, contamination of soil with antibiotics originating from manure amendment is likely to promote the invading potential of antibioticresistant manure-borne bacteria in soils.…”

“…Consequently, contamination of soil with antibiotics originating from manure amendment is likely to promote the invading potential of antibioticresistant manure-borne bacteria in soils. In that sense, antibiotics could increase the invading potential of isolated antibiotic-resistant strains in soil [27,28] and manure amendment can result in an increase of the diversity of antibiotic-resistant bacteria in soil [17].…”

The fertilization of agricultural soil by organic amendment that may contain antibiotics, like manure, can transfer bacterial pathogens and antibiotic-resistant bacteria to soil communities. However, the invasion by manure-borne bacteria in amended soil remains poorly understood, being hardly observed. Here, we assessed the invasions of manure-borne bacteria during a coalescence event between manure and soil, in different soils and in the presence or absence of antibiotics. To this end, microcosms of four different soils were amended or not with manure at an agronomical dose and/or exposed or not to the antibiotic sulfamethazine (SMZ). After one month of incubation, the diversity, structure and composition of bacterial communities of the soils were assessed by 16S rDNA sequencing. The invasion of manure-borne bacteria was still perceptible one month after the soil amendment. The results obtained with the soil already amended in situ with manure six months prior to the experiment suggest that some of the bacterial invaders were established in the community over the long term. Even if differences were observed between soils, the invasion was mainly attributable to some of the most abundant OTUs of manure (mainly Firmicutes). SMZ exposure had a limited influence on soil microorganisms. It was significant in only one soil, where it enhanced the invasion potential of some manure-borne invaders.

“…16 Xu et al reported that the tetracycline residue in soils amplied the impact of foreign antibiotic-resistant bacteria on the soil bacterial community. 17 Other studies found that antibiotic residues in soils not only changed the soil microbial community structure, 2,[18][19][20][21][22] but also inhibited carbon utilization, 23 enzyme activity, 24,25 and soil nitrication, 26 as well as leading to a reduced ratio of bacteria/fungi. 21,27 Also, the overuse of antibiotics has raised concerns on antibiotic resistance genes (ARGs).…”
