Study’s Novelty/Excerpt This study investigates chromium reduction potential of bacteria isolated from hydrocarbon-contaminated soils in the Sokoto metropolis, a specific environment previously underexplored this context. It uniquely identifies Brucella intermedia and Bacillus sp. as potent chromium-tolerant isolates with significant efficiencies, providing new insights into bioremediation capabilities these strains. Additionally, research demonstrates high removal efficacy at various concentrations, highlighting application for effective chromium-polluted water bodies. Full Abstract Hydrocarbon-contaminated are recognised reservoirs heavy metal-utilizing due to phenomenon co-selection. These can have biosorption metal. aimed screen soils. The soil samples used were collected hydrocarbon-affected sites metropolis; additionally, control sample was non-polluted soil. Bacteria using standard protocols. Variable amounts prepared potassium monochromate (K2CrO4) then incorporated nutrient broth medium. most potent, molecularly-identified hydrocarbonoclastic screened tolerance, percentage content also measured. Mean colony counts ranged from1.00×106 1.30×106 CFU/g while had 2.30×105 CFU/g. From 14 strains, two, molecularly identified NCBI BLAST Brucellaintermedia sp., shown be tolerant isolates. B. reduced Cr an initial value 350 mg/L 198 within 72 hours (44 % efficiency). At lowest concentration (50 mg/L), 96% achieved. recorded highest compared tested concentrations (50, 150, 250, mg/L). A 100% obtained 50 concentration. demonstrated that particularly reducing metal solutions different concentrations. or

Cellulomonas fimi Clb-11 can reduce high toxic Cr (VI) to low (III). In this study, transcriptomics was used analyze the key genes, which involved in uptake and reduction C. fimi Clb-11. The results showed that when C. fimi Clb-11 subjected 0.5 mM stress, 654 genes were upregulated. Among them, phosphate transport protein encoding gene phoU, inorganic TC.PIT, molybdate modA, modB, modC passive of by Clb-11. Cytochrome c subunits qcrA qcrC, as well cytochrome oxidase coxB coxC intracellular Additionally, several unreported found be upregulated under stress. Manganese mntH nickel system permease ABC.PE.P ABC.PE.P1 may participate Osmoprotectant ATP-binding opuA, osmoprotectant substrate-binding opuC, opuBD crucial for maintaining water content cells enhancing resistance (VI). Proton pump subunit atpA, atpB, atpE, atpF, atpH, sodium-hydrogen antiporter mnhA mnhC, extracellular proton secretion extracellular. Iron complex ABC.FEV.S, vacuolar iron transporter VIT, FMN reductase ssuE, quinone oxidoreductase QOR qor qorB pyruvate dehydrogenase pdhA, pdhB, pdhC, succinate sdhA, sdhB, sdhD, play important roles supplying electrons Our study provides theoretical references optimizing microbial chromium pollution remediation techniques.
