“…Numerous studies have looked at the isolation and characterization of heavy metal, and antibiotic-resistant bacteria in wastewater from places like the dumpsites (Sanuth and Adekanmbi, 2016), printeries (Adekanmbi et al, 2019), bight sediments (Timoney et al, 1978), lakes and rivers (Matyar et al, 2014), and many genera of bacteria have been discovered, including those isolated in this study. Multiple heavy metal and antibiotic resistance in Alcaligenes faecalis and Paenalcaligenes hominis from wastewater was reported by Abo-Amer et al (2015), Sanuth and Adekanmbi (2016), Adekanmbi et al (2019); Ayyal Al-Gburi (2020), Olowookere et al (2020) and Ibrahim et al (2021). According to a comparative analysis of Paenalcaligenes hominis 16S rRNA gene sequences, this bacterium shares <95 % similarity with all reported species of the Alcaligenaceae genera (Kämpfer et al, 2010).…”

“…The minimum concentration of the heavy metals that inhibits the growth of the isolates was regarded as the minimum inhibitory concentration (MIC) and was determined using the agar diffusion technique as described earlier [ 21 ] by culturing each isolate on increasing concentrations (100-500 µ g/mL) of the different heavy metals. Isolate growing at one concentration was transferred to higher concentration and the MIC was noted when the isolate failed to grow [ 22 ].…”

The indiscriminate deposition of metal-containing substances into the environment contributes significantly to high concentrations of metals in the soil resulting in resistance to metals and consequentially to antibiotics by inherent microbes which may eventually spread to other pathogenic microbes thereby elevating disease burden due to antibiotic resistance. The study aimed at determining the co-occurrence of resistance of bacteria isolated from metal-contaminated soil to heavy metals and subsequently, antibiotics. Metal-tolerant bacteria were randomly isolated from top soils from a battery waste site using the pour plate method. Selected isolates were identified using biochemical tests, then, subjected to elevating supplemented concentrations of different metal salts at 100-500 μg/mL to determine the minimum inhibitory concentration. Isolates tolerant to minimum three metals up to 400 μg/mL were subjected to Sulfamethoxazole-trimethoprim (25 μg), Imipenem (10 μg), Amoxicillin (30 μg), Ciprofloxacin (10 μg) and Tigecycline (15 μg) and observations interpreted using the guiding principle of the Clinical and Laboratory Standards Institute. Metal concentrations in the soils exceeded permissible limits. In total, 16 isolates were selected and identified as Proteus sp. (1), Pseudomonas spp. (5), Enterobacter spp. (2), Klebsiella spp. (2), Escherichia spp. (3), Raoultella spp. (2) and Rahnella sp. (1). Thirteen (81.25 %) of all isolates showed multi-resistance to the metals and seven exhibited multidrug-resistance, with 4 (57.1 %) showing resistance to three different classes of antibiotics and 3 (42.9 %) showed resistance to four antibiotic classes. Heavy metal-tolerant bacteria isolated from this study possess co-selection potentials as they showed resistance to different metals and antibiotics classes which is a concern to public health.

“…In Imron et al [18], Pseudomonas fluorescens was isolated from non-active sanitary landfill leachate with a minimum inhibitory concentration (MIC) of 5 mg L − 1 for Hg. Pseudomonas aeruginosa was isolated from the leachate of an active solid waste disposal dumpsite with MIC values of 15, 10, 12, and 9 mg L − 1 for Pb, Cr, Ni, and Cd, respectively [19]. Apart from exhibiting high resistance, bacteria isolated from contaminated areas can also remove heavy metals.…”

“…Apart from exhibiting high resistance, bacteria isolated from contaminated areas can also remove heavy metals. P. aeruginosa isolated from solid waste disposal dumpsite leachate can remove approximately 29, 30, 35, and 28% of Pb, Cr, Ni, and Cd, respectively [19]. Neneng and Gunawan [20] reported that P. aeruginosa KHY2 and Klebsiella pneumonia KHY3 isolated from gold mine wastewater exhibited the capability to remove 1000 mg L − 1 of Hg up to 60%.…”

Leachate is produced from sanitary landfills containing various pollutants, including heavy metals. This study aimed to determine the resistance of bacteria isolated from non-active sanitary landfill leachate to various heavy metals and the effect of salinity levels on the removal of Hg by the isolated bacterium. Four dominant bacteria from approximately 33 × 1017 colony-forming units per mL identified as Vibrio damsela, Pseudomonas aeruginosa, Pseudomonas stutzeri, and Pseudomonas fluorescens were isolated from non-active sanitary landfill leachate. Heavy metal resistance test was conducted for Hg, Cd, Pb, Mg, Zn, Fe, Mn, and Cu (0–20 mg L− 1). The removal of the most toxic heavy metals by the most resistant bacteria was also determined at different salinity levels, i.e., fresh water (0‰), marginal water (10‰), brackish water (20‰), and saline water (30‰). Results showed that the growth of these bacteria is promoted by Fe, Mn, and Cu, but inhibited by Hg, Cd, Pb, Mg, and Zn. The minimum inhibitory concentration (MIC) of all the bacteria in Fe, Mn, and Cu was > 20 mg L− 1. The MIC of V. damsela was 5 mg L− 1 for Hg and > 20 mg L− 1 for Cd, Pb, Mg, and Zn. For P. aeruginosa, MIC was > 20 mg L− 1 for Cd, Pb, Mg, and Zn and 10 mg L− 1 for Hg. Meanwhile, the MIC of P. stutzeri was > 20 mg L− 1 for Pb, Mg, and Zn and 5 mg L− 1 for Hg and Cd. The MIC of P. fluorescens for Hg, Pb, Mg, and Zn was 5, 5, 15, and 20 mg L− 1, respectively, and that for Cd was > 20 mg L− 1. From the MIC results, Hg is the most toxic heavy metal. In marginal water (10‰), P. aeruginosa FZ-2 removed up to 99.7% Hg compared with that in fresh water (0‰), where it removed only 54% for 72 h. Hence, P. aeruginosa FZ-2 is the most resistant to heavy metals, and saline condition exerts a positive effect on bacteria in removing Hg.
