“…Bacteria thrive in adverse natural environments by production of such secondary metabolites which enable them to retain moisture, acquire nutrients, prevent osmotic stress, resist high and cold temperatures and aid in bio lms formation. In laboratory, apart from physical chemical factors, carbon source in the medium, genetic character and growth phase of the bacterial strain can determine the chemical composition and properties of extracellular polymeric substances (Datta et al 2020;Saha et al 2020). Apart from emulsi cation of hydrophobic substances, EPS may even contain surfactant properties as reported in previous works (Uzoigwe et al, 2015).…”

“…They are called "hydrocarbonoclastic" bacteria for their role in bioremediation of hydrophobic pollutants like petroleum hydrocarbons and discharged oils (Xu et al 2018;Yakimov et al 2007). In context of environmental bioremediation, such eco-friendly practices can be done by employing bacteria alone or by their metabolites (Datta et al 2020;Sengupta et al 2018). For instance, in previous studies Ochrobactrum pseudintermedium C1 has produced an extracellular polymeric substance (EPS) which help in enhancing emulsi cation of complex hydrocarbon wastes like engine and cutting oil (Bhattacharya et al 2014;Sengupta et al 2019).…”

Mineral lubricating oils are widely used in various industrial sectors for their applications in maintenance and functioning of machineries. However, indiscriminate dumping of these used oils has resulted in polluting the natural reservoirs which subsequently destroys ecological balance. Bacteria can emulsify or lower surface tension between phases of immiscible substrates and can acquire them as their carbon and energy sources. Such a phenomenon is mediated by synthesis of extracellular polymeric substances which can function as eminent surface active compounds based on their surfactant or emulsifying nature. The comparison between bacterial strains (Gram-positive Bacillus stratosphericus A15 and Gram-negative Ochrobactrum pseudintermedium C1) on utilisation of pure straight chain hydrocarbons, waste mineral lubricating oils as sole carbon source and chemical characterization of the synthesized surface active compounds is studied. Characterization analysis by Ultraviolet Visible spectrophotometry, Fourier-transform infrared spectroscopy, Nuclear Magnetic Resonance spectroscopy, Carbon-Hydrogen-Nitrogen analysis has given detailed structural elucidation of surface active compounds. The contrasting nature of bacterial strains in utilisation of different hydrocarbons of spindle oil was observed in Gas Chromatography-Mass Spectroscopy. The variation between both strains in utilisation of hydrocarbons can be manifested in a difference in chemical structure and properties of the synthesized surface active compounds. Scanning Electron Microscopy gives detailed insight into the difference in morphological nature of the compounds. The utilisation of these lubricating oils can address waste disposal problem and offer an economical feasible approach for bacterial synthesis of surface active compounds. Additionally, their distinctive nature and properties can maneuver applications in bioremediation of toxic environmental pollutants and as biomaterials in pharmaceutics.

“…It plays a significant role in numerous naturally occurring processes across various scientific disciplines. Several studies have demonstrated that numerous organisms, including prokaryotes and eukaryotes, have varying natural capacities to biosorb hazardous heavy metal ions as well as toxic dyes ( Datta et al, 2020 ). Anoxybacillus rupiensis TPH1 was identified from the Tattapani hot spring in Chhattisgarh, India.…”

Toxic wastes like heavy metals and dyes are released into the environment as a direct result of industrialization and technological progress. The biosorption of contaminants utilizes a variety of biomaterials. Biosorbents can adsorb toxic pollutants on their surface through various mechanisms like complexation, precipitation, etc. The quantity of sorption sites that are accessible on the surface of the biosorbent affects its effectiveness. Biosorption’s low cost, high efficiency, lack of nutrient requirements, and ability to regenerate the biosorbent are its main advantages over other treatment methods. Optimization of environmental conditions like temperature, pH, nutrient availability, and other factors is a prerequisite to achieving optimal biosorbent performance. Recent strategies include nanomaterials, genetic engineering, and biofilm-based remediation for various types of pollutants. The removal of hazardous dyes and heavy metals from wastewater using biosorbents is a strategy that is both efficient and sustainable. This review provides a perspective on the existing literature and brings it up-to-date by including the latest research and findings in the field.
