“…The biosurfactant producing microorganisms possesses a biodegradable behavior compared with synthetic components that is considered friendly to environmental. Another advantage relieves from biosurfactant producing microorganisms that is considered a cost effective material produces in situ Franzetti et al 2014). Several attempts have been carried out to restore heavy metal (Zn, Cu, Cr, Hg, Cd and Pb) containing wastewater and polluted soil using the biosurfactant producing microorganisms (Zouboulis et al et al et al et al Huang and Liu, 2013).…”

In the present study, the effects of biosurfactant producing cells of different bacterial species namely Pseudochrobactrum lubricantisa, Lysobacter novalis, and crude biosurfactant extracted from Aspergillus niger were investigated as a cheap source to alleviate the availability of Pb 2+ for plants grown in El-Gabal El-Asfar area, Egypt. This is owing to these areas are basically depend on the reused wastewater for irrigation. Biosurfactant producing microorganisms were isolated from three different farms aged for 20, 40, and 60 years. The obtained results showed that, the biosurfactant producing bacteria decreased the availability of Pb 2+ in the outlet leachate during the leaching columns experiments. In contrast, Sr 2+ leachate showed the reverse trend that was observed with Pb 2+. Taguchi approach indicated that, the mechanisms of biosurfactant producing bacteria are very complicated and interfused with each other. The most factors affected the available form of Pb 2+ and Pb 2+ existed in organic form was Pb 2+ concentrations, however the exchangeable Pb 2+ , Pb 2+ bond to carbonate, Pb 2+ bond to sulfate, and plant content the most influential factors was biosurfactant producing bacteria. The most influential factors affected NPK uptake by watercress were found to take the following sequence biosurfactant producing bacteria > Sr 2+ doses > Pb 2+ doses.

“…They contain hydrophobic and hydrophilic moieties that decrease the surface and interfacial tension between surfaces (Maneerat, 2005). Biosurfactants possess important characteristics that offer advantages over synthetic surfactants, which include surface and interfacial activity, tolerance to temperature, pH, and ionic force, low toxicity, availability, specificity, biocompatibility, and biodegradability (Kiran et al, 2010a;Franzetti et al, 2014). Because of their promising benefits, they are extensively used for industrial and medicinal purposes (Muthusamy et al, 2008).…”

Biosurfactants are amphiphilic molecules which showed application in the food, medical, and cosmetics industries and in bioremediation. In this study, a marine spongeassociated bacteria (MSI 54) was identified as a biosurfactant producer which showed high emulsification and surface tension-reducing property. The isolate MSI 54 was identified as Bacillus sp. and the biosurfactant was chemically characterized as a lipopeptide analog based on the spectral data including Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. The MSI 54 lipopeptide biosurfactant was an anionic molecule which showed high affinity toward cationic heavy metals including Pb, Hg, Mn, and Cd. The heavy metal bioremediation efficacy of the biosurfactant was evaluated using atomic absorption spectroscopy, scanning electron microscopy/energy-dispersive X-ray spectroscopy, and high-resolution transmission electron microscopy analysis. When MSI 54 lipopeptide biosurfactant was added to heavy metals, this resulted in a white co-precipitate of the metal-biosurfactant complex. The heavy metal remediation efficacy of the biosurfactant at a 2.0 × critical micelle concentration (CMC) showed removal of 75.5% Hg, 97.73% Pb, 89.5% Mn, and 99.93% Cd, respectively, in 1,000 ppm of the respective metal solution. The surface treatment of farm fresh cabbage, carrot, and lettuce with 2.0 × CMC of the lipopeptide showed effective removal of the surface heavy metal contaminants.

“…To our knowledge, several good review articles focused on specific topics of rhamnolipids in therapeutic, biomedical, pharmaceutical, and industrial applications have been published (Banat et al, ; Gudiña, Rangarajan, Sen, & Rodrigues, ; Inès & Dhouha, ; Nitschke, Costa, & Contiero, ). Also, several reviews (Abdel‐Mawgoud et al, ; Mao, Rui, Wei, & Yu, ; Mulligan, ; Pacwa‐Płociniczak, Płaza, Piotrowska‐Seget, & Cameotra, ) and book chapters (Açıkel, ; Franzetti et al, ) have summarized the data on the performance of rhamnolipids in enhancing organic contaminated soil and heavy metal contaminated soil remediation. However, these reviews and book chapters do not report a comprehensive evaluation of the studies of rhamnolipids in soil remediation, including rhamnolipid‐based bioremediation and soil washing technologies, as well as treatment of the washing effluent and so on.…”

The objective of this review is to provide a comprehensive overview of the advances in the applications of rhamnolipids biosurfactants in soil and ground water remediation for removal of petroleum hydrocarbon and heavy metal contaminants. The properties of rhamnolipids associated with the contaminant removal, that is, solubilization, emulsification, dispersion, foaming, wetting, complexation, and the ability to modify bacterial cell surface properties, were reviewed in the first place. Then current remediation technologies with integration of rhamnolipid were summarized, and the effects and mechanisms for rhamnolipid to facilitate contaminant removal for these technologies were discussed. Finally rhamnolipid-based methods for remediation of the sites co-contaminated by petroleum hydrocarbons and heavy metals were presented and discussed. The review is expected to enhance our understanding on environmental aspects of rhamnolipid and provide some important information to guide the extending use of this fascinating chemical in remediation applications.
