“…The heavy metal ion removal efficiency found for several ions, like Co 2+ or Ni 2+ , is impressively high, especially if one considers that nearly no optimization has been performed, as otherwise reported for with other systems (De Franҫa et al, 2015; Talbot et al, 2018), and the mixing protocol is relatively simple. The comparison with other biosurfactants is not straightforward, as most work has been carried out on soil depollution (Chen et al, 2021; Kim & Vipulanandan, 2006; Malkapuram et al, 2021; Miller, 1995; Mishra et al, 2021; Mulligan, 2005, 2009, 2021; Mulligan et al, 2001; Mulligan & Wang, 2006; Mulligan, Yong, & Gibbs, 1999; Mulligan, Yong, Gibbs, James, & Bennett, 1999; Ochoa‐Loza et al, 2001b; Sonowal et al, 2022), rather than aqueous solutions (Ghaith et al, 2019; Huang & Liu, 2013; Kim & Vipulanandan, 2006). In the latter case, the biosurfactants (generally rhamnolipids) are not employed alone but in association with biomass, like dry ground grass or bacteria, or the nature of the biosurfactant itself is not clarified (Kim & Vipulanandan, 2006).…”

“…Peptides amphiphiles (Abdellatif et al, 2020; Bhattacharya & Krishnan‐Ghosh, 2001; Suzuki et al, 2006) and, more importantly, microbial biosurfactants, like rhamnolipids, sophorolipids or surfactin (Chen et al, 2021; Hari & Upadhyay, 2021; Malkapuram et al, 2021; Mishra et al, 2021; Mulligan, 2021; Singh & Cameotra, 2013), have been shown to have interesting depollution properties against both organic and heavy metal pollutants. However, in the latter case, the essential work, which has started more than 30 years ago, has been carried out on soil pollution (Chen et al, 2021; Kim & Vipulanandan, 2006; Malkapuram et al, 2021; Miller, 1995; Mishra et al, 2021; Mulligan et al, 2001; Mulligan, 2005, 2009, 2021; Mulligan, Yong, & Gibbs, 1999; Mulligan, Yong, Gibbs, James, & Bennett, 1999; Mulligan & Wang, 2006; Prakash et al, 2021; Sonowal et al, 2022), with relatively less contributions to water depollution.

Water pollution by heavy metals is a problem of both western and developing countries.Heavy metal pollution can be associated to human activity, such as wastewaters from processing of ore mining, but also to simple contamination from metal rich soils. Whichever the case, chemical and physical methods are generally employed to depollute water. Since most chemicals are themselves polluting agents, there is an increasing interest in finding biobased and biodegradable alternative chemicals, both efficient in removing metals and benign to the environment. Biosurfactants are green chemicals produced by fermentation of yeasts and bacteria and with a good environmental score. Among many applications, this class of compounds has been used to remove heavy metals from contaminated soils. Within this framework, we propose a new mechanism of depolluting water using a glucolipid biosurfactant, G-C18:1, composed of glucose (G) and a C18:1 fatty acid (oleic acid). This compound is able to form a metallogel by complexing cations in water, thus trapping heavy metals (Cu 2+ , Ni 2+ , Cr 2+ and Co 2+ ) in the gel phase. This mechanism allows to remove up to 95% for cobalt and 88 ± 10%, 80 ± 3% and 59 ± 6% for Cu 2+ , Ni 2+ and Cr 2+ , respectively. A dedicated structural study shows that this is possible because positively charged species induce gelation of G-C18:1 through a micelle-to-wormlike phase transition, most likely driven by a charge neutralization process. This work shows that wise control of the nanoscale properties of green chemicals can strongly benefit to develop a sustainable future.

Soil contamination is a significant environmental issue that poses a threat to human health and the ecosystems. Conventional remediation techniques, such as excavation and landfilling, are often expensive, disruptive, and unsustainable. As a result, there has been growing interest in developing sustainable remediation strategies that are cost‐effective, environmentally friendly, and socially acceptable. One such solution is phytoextraction: a nature‐based approach that uses the abilities of hyperaccumulator plants to uptake and accumulate metals and metalloids (potentially toxic elements [PTE]) without signs of toxicity. Once harvested, plant biomass can be treated to reduce its volume and weight by combustion, thus obtaining bioenergy, and the ashes can be used for the recovery of metals or in the construction industry. However, phytoextraction has shown variable effectiveness due to soil conditions and plant species specificity, which has led researchers to develop additional approaches known as assisted phytoextraction to enhance its success. Assisted phytoextraction is a remediation strategy based on modifying certain plant traits or using different materials to increase metal uptake or bioavailability. This review article provides a practical and up‐to‐date overview of established strategies and the latest scientific advancements in assisted phytoextraction. Our focus is on improving plant performance and optimizing the uptake, tolerance, and accumulation of PTE, as well as the accessibility of these contaminants. While we highlight the advantages of using hyperaccumulator plants for assisted phytoextraction, we also address the challenges and limitations associated with this approach. Factors such as soil pH, nutrient availability, and the presence of other contaminants can affect its efficiency. Furthermore, the real‐world challenges of implementing phytoextraction on a large scale are discussed and strategies to modify plant traits for successful phytoremediation are presented. By exploring established strategies and the latest scientific developments in assisted phytoextraction, this review provides valuable guidance for optimizing a sustainable, nature‐based technology.
