Arsenic-resistant Klebsiella oxytoca strain AT-02 was isolated from the ground water of Multan region Pakistan. The displayed high arsenite and arsenate resistance as minimal inhibitory concentration (MIC) 600ppm 10,000ppm respectively. tolerance towards can be postulated due to significant increase in biofilm response arsenate. bacterial exposed 1/2 3/4 MIC showed a 10 12 folds expression efflux gene arsB. Sequential structural comparison arsB presence conserved arsenic binding residues. Arsenic remediation by biomass 50% after 0.5 hours incubation 66% 2 hours. efficiency with time indicates its biosorption potential. sensitive NK11 only 4-5% remediation. Fourier transform infrared spectroscopy (FTIR) analysis confirmed interaction functional groups (aromatic amino acid residues) on cell surface leading characteristic peak shifts. Thus, has potential remediate both contaminated environmental sites.

This review explores the potential of macroalgae in heavy metal phytoremediation, focusing on their ability to absorb and sequester toxic metals from contaminated aquatic environments. Heavy metals, pose significant ecological health risks due persistence bioaccumulation. Phytoremediation, particularly using macroalgae, offers a sustainable, eco-friendly alternative traditional chemical methods. Data various studies show that species such as Sargassum wightii , Caulerpa racemosa Durvillaea antarctica demonstrate high efficiency removing metals. The discusses key challenges scaling up cultivation safe disposal metal- laden biomass. Additionally, it highlights gaps current research, emphasizing need for standardized protocols further investigation into mechanisms uptake. Overall, macroalgae-based phytoremediation presents promising solution mitigating pollution enhancing ecosystem health.

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

Industrial activities, pharmaceutical contaminants, excessive agricultural inputs, and improper waste disposal have contributed to the widespread pollution of soil water. Traditional remediation techniques, while effective, often generate secondary are economically unfeasible. In contrast, microbial bioremediation offers a sustainable cost-effective alternative by utilizing microorganisms their enzymatic systems degrade detoxify pollutants. This review investigates potential enzymes in strategies for removing heavy metals contaminants from polluted environments. It analyzes fundamental mechanisms which sequester these pollutants, emphasizing processes that facilitate breakdown. Furthermore, it explores key factors influencing efficiency, including diversity environmental conditions. Additionally, examines challenges associated with scaling global applications provides insights future research implementation.

Geothermal ecosystems are defined by extreme environmental conditions, such as elevated temperatures, high concentrations of toxic chemicals, and fluctuations in abiotic stressors, which shape plant survival adaptation. These unique ecosystems, found across various geothermal regions globally, support specialized communities that have developed distinctive morphological, physiological, ecological adaptations. Indonesia, located on the Pacific Ring Fire, is one world’s richest nations, offering an important yet underexplored context for studying vegetation zones. This review examines conditions adaptive strategies vegetation, patterns diversity within Indonesian fields. It also explores succession, community dynamics, potential use indicators biomonitoring. Despite growing interest, significant research gaps remain, particularly long-term monitoring integration molecular-level studies. Addressing these essential enhancing scientific understanding informing conservation sustainable energy development tropical regions. highlights significance underscores need interdisciplinary to both biodiversity preservation responsible exploitation.
