Summary: The study investigates the bioremediation potential of a nickel-resistant bacterial isolate, Bacillus altitudinis MT422188, showing efficient removal of Ni from polluted industrial effluents. The bacteria displayed optimal growth parameters at pH 7, temperature 32 degrees C, and 1 mM phosphate, with Ni biosorption facilitated by an ATP-independent efflux system.

Summary: Fungal melanins exhibit promising biosorption properties for metal-contaminated effluents treatment. Melanin pigment derived from Amorphotheca resinae showed high adsorption capacities for Cu(II), Pb(II), Cd(II), and Zn(II) in aqueous solutions, with an affinity sequence of Cu(II)>Pb(II)>Cd(II)>Zn(II). The chelating ability of free radicals in the pigment contributes to its efficient adsorption, making it a suitable biosorbent for metal-contaminated wastewater treatment.

Summary: Predicting the transport and fate of organic and inorganic contaminants in co-contaminated soils is challenging due to the complex, inter-related processes involved. Optimum spatial distribution patterns of microbial colonies can effectively restrict the spread of both organic and inorganic contaminants, reducing environmental impacts.

Summary: In this study, microorganisms with high resistance to lead ions were isolated and evaluated for their efficiency in removing lead ions from wastewater through biosorption. The optimized conditions for biosorption of Pb (II) were determined, and the biosorption efficiency and capacity of the isolated Brevibacillus strain were analyzed. Surface characterization and analysis of key functional groups involved in biosorption were conducted. The results showed that the biomass of Brevibacillus can be used as a promising biosorbent for the removal of metals, including lead, from wastewater.

Summary: Due to rising populations and human activities, heavy metals toxicity has become a serious problem. This study isolated and identified lead-resistant bacteria from contaminated wastewater, and found that Bacillus cereus and Bacillus sp. both resisted a 25 mM concentration of Lead nitrate. After treatment, it was observed that these strains could potentially be useful in bioremediating heavy metals in polluted environments.

Summary: This study investigated the culturable bacteria isolated from uranium ore samples from Aborshid Egypt, and found that there was no acquired antibiotic resistance among potential environmental isolates, while potentially pathogenic isolates presented a broad diversity of acquired antibiotic resistance. The ore bacteria showed varying response to heavy metals, with all isolates exhibiting multiple metal resistances.
