Characterization of Bacterial Isolates from Tailings Pond and Their Resistance to Heavy Metals and Antibiotics
lWater samples were collected from a tailings pond wastewater site in the Rudnik mountain area, where polymetallic ore flotation processes generate high concentrations of Pb2+, Zn2+, and Cu2+. The study aimed to identify microorganisms resistant to heavy metals and assess their potential for bioremediation. Growth capabilities under varying conditions, including temperature, pH, and NaCl concentrations, were analyzed using a spectrophotometer. Minimal inhibitory and lethal concentrations of tested substances were determined for both planktonic cells and their biofilms. Key isolates, namely Bacillus altitudinis PMFKG-R3, B. pumilus PMFKG-R15, B. cereus PMFKG-R46, Pseudomonas veronii PMFKG-R30, and Pantoea agglomerans PMFKG-R20, demonstrated growth ability at both 22 and 37°C and exhibited halotolerance, albeit sensitivity to acidic pH. Most isolates in both planktonic and biofilm forms displayed notable resistance to heavy metals, particularly Pb2+ and Zn2+, in line with the sampling location. Notably, planktonic cells were sensitive to antibiotics, while biofilms exhibited slightly higher resistance. Promising candidates for bioremediation purposes were identified in P. veronii PMFKG-R30 and P. agglomerans PMFKG-R20, which displayed resistance to heavy metals and sensitivity to antibiotics.
期刊介绍:
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
