The biosorption of heavy metals has become an attractive alternative to conventional methods and is considered feasible, environmentally friendly often low-cost option. Five microorganisms (Rhodotorula sp., Cladosporium Bacillus megaterium, Trichosporon sp. Geotrichum sp.) were isolated from different environments used for the Cd(II) aqueous solutions in batch mode expand upon existing studies generate new data related main that could be successfully applied removal wastewaters. Considering a constant biosorbent dose (5 g/L), pH (5.4) temperature (25 °C) varying contact times initial pollutant concentrations, process efficiency uptake capacity biosorbents assessed. Statistical analysis experimental results revealed time longer than 24 h did not significantly increase or by B. megaterium which means available binding sites on cell wall immediately participate metal ions. For other three biosorbents, increasing 48 led significant efficiency. A comparison values each had highest (8.53 mg/g), followed (8.21 mg/g). lowest capacity, as well after contact, was obtained (0.73 mg/g 14.97%, respectively). FTIR almost all functional groups present surface biosorbent, but their involvement differed biosorbent. phosphodiester, amide hydroxyl found Rhodotorula involved biosorption.

Palm oil mill effluent (POME) has a high concentration of organic matter and total suspended solids. However, improper disposal refining wastes containing oils, fats, sludge can cause environmental damage harm human health due to their toxic, carcinogenic, polluting effects. This research was carried out solve the harmful effects caused by release POME environment. The goal this study isolate naturally occurring bacterium that could degrade use it as single carbon source. Bacteria were isolated from POME-contaminated medium using an enrichment technique. Judging 16S rRNA partial gene sequencing, morphological, biochemical, molecular identification methods, bacteria identified novel Bacillus sp. substrate concentration, inoculum size, pH, temperature, incubation time on bacterial growth investigated "one factor at time" (OFAT) approach. optimal conditions for bacterium's found be pH 7.5, 35 °C, 20 % v/v 6 96 hours incubation. is capable reducing 84 COD 91 BOD sample. degradation potential suggests used good option bioremediation POME-polluted areas.

Fungal processes for the treatment of dye contaminated wastewater have advantage being cost-effective, environmentally friendly, and producing less sludge. This research was therefore aimed at isolating characterizing fungus capable decolourizing utilizing azo (dimethyl yellow) as a sole carbon source using one-factor-at-a-time. Pour plating method used to isolate on mineral salt media (MSM) following serial dilution. The then morphologically molecularly identified Aspergillus quadrilineatus strain BUK_BCH_BTE1 with accession number OK178927 based ITS1 ITS2 rRNA gene sequence molecular phylogenetic analysis. Characterization conducted by studying effect temperature, incubation time, substrate concentration, pH, inoculum size heavy metals. decolourization growth dimethyl yellow isolated optimal concentration 200 μɡ/mL, temperature 30 °C, 100–200 μL size, pH 5.0, 72-hour time. found tolerate up 4 ppm Hg, Cu Zn, maximum inhibition shown Cr Ar. LC/MS analyses intermediate compounds produced during suggested that in fungal biodegradation detected formation yellow, 2,6-dichloro-p-benzoquinone, 1,2,3,5-tetrafluoro-4-nitrobenzene, 3,4-dinitrobenzoic acid metabolites. finding from this study is suitable candidate bioremediation coloured effluents particularly containing these compounds.

The rapid growth of the Electrical and Electronic Equipment (EEE) industry has led to an increase in Waste (WEEE) generation Nigeria. informal sector plays a significant role WEEE recycling, but unsustainable practices pose environmental health risks. Unsustainable EEE recycling Nigeria's result pollution, hazards, economic losses. lack regulation, inadequate infrastructure, limited awareness exacerbate problem, putting recyclers, communities, environment at risk. This review synthesizes existing literature on impacts sector. Informal Nigeria are characterized by primitive techniques, such as burning dismantling, leading air, water, soil pollution. Cultural socioeconomic factors influence collection, require region-specific approaches. availability technical capacity, resources differs across regions, affecting feasibility proposed solutions. By acknowledging these factors, findings from Nigerian context can be adapted applied other contributing more comprehensive understanding management challenges solutions globally.
