Microbial electrochemical technologies (MET) are increasingly being considered for environmental remediation applications, mainly their unique capability to enhance microbial degradation processes in an environmentally sustainable manner (e.g., without requiring addition of chemicals and with little or even no energy consumption). To date, however, the application MET saturated unsaturated soils contaminated by petroleum hydrocarbons (PH) remains challenged a number operational factors which have, so far, hampered more rapid deployment technology.

Today, environmental pollution is a serious problem, and bioremediation can play an important role in cleaning contaminated sites. Remediation strategies, such as chemical physical approaches, are not enough to mitigate problems because of the continuous generation novel recalcitrant pollutants due anthropogenic activities. Bioremediation using microbes eco-friendly socially acceptable alternative conventional remediation approaches. Many with potential have been isolated characterized but, many cases, cannot completely degrade targeted pollutant or ineffective situations mixed wastes. This review envisages advances systems biology (SB), which enables analysis microbial behavior at community level under different stresses. By applying SB approach, crucial preliminary information be obtained for metabolic engineering (ME) their enhanced capabilities. also highlights integrated ME tools techniques purposes.

A crude oil spill is a common issue during offshore drilling, transport and transfer to onshore. Second, the production of petroleum refinery effluent known cause pollution due its toxic discharge. Sea habitats onshore soil biota are affected by total hydrocarbons (TPH) as pollutant in their natural environment. Crude seawater, estuaries beaches requires an efficient process cleaning. To remove pollutants from various physicochemical biological treatment methods have been applied worldwide. method using bacteria, fungi algae has recently gained lot attention efficiency lower cost. This review introduces studies related bioremediation oil, TPH products bioaugmentation biostimulation or both together. Bioremediation mentioned this paper can be used for such emulsified residual spilled seawater with floating containment booms enclosed basin bioreactor, that will help environmental researchers solve these problems completely clean-up spills seawater.

Petroleum hydrocarbons (PHs) are used as raw materials in many industries and primary energy sources. However, excessive PHs act soil pollutants, posing serious threats to living organisms. Various ex-situ or in-situ chemical biological methods applied restore polluted soil. most of the treatment expensive, environmentally unfriendly, sometimes inefficient. That attracts scientists researchers develop select new strategists remediate through risk-based analysis eco-friendly manner. This review discusses sources PHs, properties, distribution, transport, fate environment, internal external factors affecting remediation restoration process, its effective re-utilization for agriculture. Bioremediation is an method degrading specifically by using microorganisms. Next-generation sequencing (NGS) technologies being monitor contaminated sites. Currently, these have caused a paradigm shift giving insights into microbially mediated biodegradation processes targeting rRNA discussed concisely. The recent development management contamination challenges future perspectives also discussed. Furthermore, nanotechnology seems very promising remediation, but success depends on cost-effectiveness. paper suggests bio-electrochemical systems that utilize electro-chemically active microorganisms with would be eco-friendlier help tailor-made sustainable technologies.

In the present work, operational conditions for improving degradation rates of Total Petroleum Hydrocarbons (TPHs) in contaminated soil from a machinery park were optimized at microcosms scale along 90-days incubation period. this study, bioremediation strategies and an organic amendment have been tested to verify remediation with different hydrocarbons, mineral oils, heavy metals. Specifically, designed biostimulation bioaugmentation compared without adding vermicompost. The polluted harboring multiple contaminants, partially attenuated years, was used. initial profile showed enrichment linear alkanes, suggesting previous moderate weathering. application vermicompost increased five two times amounts available phosphorus (P) exchangeable potassium (K), respectively, as direct consequence addition. microbial activity due acidification, which influenced solubility P other micronutrients. It also impacted predominance variability groups incubation, reflected by phospholipid fatty acid (PLFA) results. An increase alkaline phosphatases proteases linked bacterial growth displayed. This stimulation metabolism correlated since TPHs degradation' efficiency after addition reached 32.5% 34.4% hydrocarbon levels bioaugmentation, respectively. Although Polycyclic Aromatic (PAHs) less abundant soil, results decreased, especially most abundant, phenanthrene. Despite rates, revealed that recalcitrant hydrophobic petroleum compounds remained unchanged, indicating mobility, bioavailability, probably represents limiting step further recovery.

Global environmental pollutants are becoming intense because of the increasing human population, urbanisation, and industrialisation. Human health ecosystem affected by soil water contamination. Therefore, creating strategies is essential to tackle this persistent issue. In process, risk associated with these can be signifi-cantly reduced. Previously, traditional remediation techniques have been employed in combating pollutants, proving ineffective. Mycoremediation, which uses fungi or their compounds remediate has shown a cost-efficient, environmen-tally friendly, effective method that includes organic, inorganic, emerging contaminants (antibiotics, pharmaceuticals).
