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.

Glyphosate can disrupt the food chain and harm non-target organisms, highlighting need to remediate contaminated soils. This study sought determine efficacy of co-applying mixed microbial culture (MMC) two different levels nitrogen (50% 100%) in glyphosate-contaminated soil (800 mg/kg) assess their role maize (Zea mays L.) growth physiology glyphosate uptake by plants removal from soil. The results showed that posed significant phytotoxicity causing up 43.7-91.5%, 8.60-54.3%, 13.2-51.6% reduction nutrient uptake, physiological, attributes soil, respectively. co-application MMC recommended dose 100% significantly improved agronomic (24.6-55.0%), (37.4-90.0%), physiological (16.9-54.0%) as compared unamended controls. Although individual application or N was effective improving further enhanced this effect removing 85.8% higher than respective control. research strategy contributes sustainable development goal 2 (zero-hunger) 15 (life on land) enhancing production, remediating restoring ecosystem.

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.
