Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil. Efforts mitigate impacts involve combination physical, chemical, biological technologies. Physical washing, flushing, thermal desorption focus on removing or isolating contaminants, while chemical approaches as oxidation, reduction, stabilization transform harmful forms immobilize them. Biological leverages microorganisms plants detoxify sustainably. Bioremediation strategies aid bioaugmentation biostimulation do enhance activity address inorganic effectively more than physical methods. Another excellent called phytoremediation can also effectively, Achieving better technique should be coupled stringent industrial regulations, sustainable tanning methods, stakeholder awareness

Biosurfactants are a group of environmentally friendly amphiphilic molecules that applicable in numerous industries as essential biotechnology products, such food production, cleaning pharmacology, cosmetics, pesticides, textiles and oil gas fields. In this sense, knowing the potential these biomolecules, aim work was to produce biosurfactant, characterize it regarding its chemical surfactant properties investigate removal contaminants cotton fabrics. The biosurfactant initially obtained from cultivation microorganism Candida glabrata UCP 1002 medium containing distilled water with 2.5% residual frying oil, molasses corn steep liquor agitated at 200 rpm for 144 h. reduced surface tension 72 29 mN/m. toxicity evaluated using Tenebrio molitor larvae demonstrated non-toxicity. applied degreaser engine on fabric, showed 83% (2× CMC), 74% (1× CMC) 78% (1/2× removal. Therefore, produced has promising emulsifying application various industrial segments.
