“…Two new strains of lactic acid bacteria (LAB), namely, Limosilactobacillus fermentum CN-005 and Lactobacillus fermentum CN-011, were identified for their high sorption capacity and tolerance to Pb(II) [ 70 ]. These strains were utilized for the effective biosorption of Pb(II) from simulated wastewater ( Table 2 ).…”

This article explores recent advancements and innovative strategies in biosorption technology, with a particular focus on the removal of heavy metals, such as Cu(II), Pb(II), Cr(III), Cr(VI), Zn(II), and Ni(II), and a metalloid, As(V), from various sources. Detailed information on biosorbents, including their composition, structure, and performance metrics in heavy metal sorption, is presented. Specific attention is given to the numerical values of the adsorption capacities for each metal, showcasing the efficacy of biosorbents in removing Cu (up to 96.4%), Pb (up to 95%), Cr (up to 99.9%), Zn (up to 99%), Ni (up to 93.8%), and As (up to 92.9%) from wastewater and industrial effluents. In addition, the issue of biosorbent deactivation and failure over time is highlighted as it is crucial for the successful implementation of adsorption in practical applications. Such phenomena as blockage by other cations or chemical decomposition are reported, and chemical, thermal, and microwave treatments are indicated as effective regeneration techniques. Ongoing research should focus on the development of more resilient biosorbent materials, optimizing regeneration techniques, and exploring innovative approaches to improve the long-term performance and sustainability of biosorption technologies. The analysis showed that biosorption emerges as a promising strategy for alleviating pollutants in wastewater and industrial effluents, offering a sustainable and environmentally friendly approach to addressing water pollution challenges.

In this study, the use of fungal (Panaeolus papilionaceus) biomass as a biosorbent was investigated to effectively remove Pb2+ ions from aquatic medium. The removal of Pb2+ ions using a fungal biosorbent was examined in a batch system in terms of initial solution pH, temperature, time, and initial Pb2+ concentration. Optimal operating conditions for biosorption of Pb2+ ions; pH: 4.5, T: 25 °C, and t: 24 h. The max biosorption capacity for Pb2+ ions was found to be 31.2 mg g−1 from the Langmuir model. Thermodynamic studies showed that Pb2+ ions biosorption into fungal biomass was possible, spontaneous, and endothermic. Additionally, the antimicrobial activity and antibiofilm activity of the extract of fungus were also investigated. It was determined that the fungal extract did not have antimicrobial properties. On the other hand, the extract has been shown to have the potential to prevent biofilm formation. 1 mg of the extract prevented the biofilm formation of Staphylococcus aureus by 87.85%. It has been observed that the biosorption mechanism of Pb2+ ions into fungal biomass includes the steps of surface biosorption, film diffusion, and intra-particle diffusion.
