“…Higher surface energy indicates higher adsorption capacity [48]. It is in agreement with the previous research that A. brasiliensis adsorbed surfactant linearly as the surfactant concentration increased [24]. Moreover, Khan et al [28] found that bacteria firmly adhered to the higher surface energy of self-assembled monolayers (SAMs) surface.…”

“…For fungi CAM experiments, the method from Smits et al [33] was adapted with modification as explained by Hamzah et al [24]. Briefly, the PDA was freshly prepared in plastic petri dishes and allowed to solidify, followed by placing the 8 μm pore size and 47 mm diameter of MCE membrane filter (Millipore, Merck) on top of the agar.…”

“…Surfactants as the surface-active agent were found to modify the surface hydrophobicity of bacteria and fungi, thereby affecting the degradation activity [21][22][23][24][25]. For example, rhamnolipid and tergitol could alter the hydrophobicity of R. erythropolis 3586 and hydrophilicity of P. putida 852 to different extents [26].…”

Bacterial adhesion on surfaces is an essential initial step in promoting bacterial mobilization for soil bioremediation process. Modification of the cell surface is required to improve the adhesion of bacteria. The modification of physicochemical properties by rhamnolipid to Pseudomonas putida KT2442, Rhodococcus erythropolis 3586 and Aspergillus brasiliensis ATCC 16404 strains was analysed using contact angle measurements. The surface energy and total free energy of adhesion were calculated to predict the adhesion of both bacteria strains on the A. brasiliensis surface. The study of bacterial adhesion was carried out to evaluate experimental value with the theoretical results. Bacteria and fungi physicochemical properties were modified significantly when treated with rhamnolipid. The adhesion rate of P. putida improved by 16% with the addition of rhamnolipid (below 1 CMC), while the increase of rhamnolipid concentration beyond 1 CMC did not further enhance the bacterial adhesion. The addition of rhamnolipid did not affect the adhesion of R. erythropolis. A good relationship has been obtained in which water contact angle and surface energy of fungal surfaces are the major factors contributing to the bacterial adhesion. The adhesion is mainly driven by acid-base interaction. This finding provides insight to the role of physicochemical properties in controlling the bacterial adhesion on the fungal surface to enhance bacteria transport in soil bioremediation.

The recent SARS-CoV-2 pandemic brought to light the difficulty in controlling the pathogenic bioaerosols present in the air. So, several studies have sought efficient and mainly sustainable technologies to develop new filtering media and new biocidal and virucidal agents. Filter media composed of nanofibers stand out for having high collection efficiencies and high permeability. For this reason, they have been widely used in filters for indoor environments and in face masks. Combined with nanofibers or conventional filtering media, the addition of quaternary ammonium surfactants to provide biocidal action proves to be an ecologically sustainable alternative. Thus, the present work reviews these filtering mechanisms, their applications, and perspectives for novel uses of these technologies in engineering and materials science.

“…6 Similarly, Hamzah et al reported the ability of 1.0 CMC rhamnolipids to be adsorbed 20% more than the nonionic surfactant; 0.5 CMC triton X-100 on the hyphae cell surface of the Aspergillus brasiliensis resulted in a gradual reduction in the fungal hydrophobicity. 124 Ruiz-Aguilar et al examined the effect of different non-ionic surfactants, triton X-100 (75 mg/L), tween 80 (302 mg/L), and Tergitol NP-100 (74 mg/L), on the growth of Trametes versicolor and found that tween 80 had no inhibitory effect on the growth of the fungi, whereas the presence of triton X-100 and tergitol NP-100 exhibited a 75-95% growth inhibition. 125 During the bioremediation process, lignocellulosic material (specifically cellulose) has been introduced in the mycoremediation site as a selective nutrient for the growth of fungi.…”

Soil contaminated with hydrophobic organic hydrocarbons, such as polycyclic aromatic hydrocarbons (PAHs), pose a serious threat to the ecosystem and human health. Moreover, the sorption and desorption of the PAHs, due to the interaction with the soil organic matter (SOM) and other contaminants, greatly affect the fate and mycoremediation efficiency of the contaminated soil. On the other hand, the application of surfactants with or without additives for the mobilization of PAHs from contaminated soil has garnered increasing attention for soil remediation. In this context, several commercial surfactants and biosurfactants were reported either as soil flushing agents or soil additives, followed by either in situ or ex situ mycoremediation of the PAHs from contaminated soil. Hence, for a successful implementation of surfactants for mycoremediation of contaminated soil, a comprehensive introspection on its chemistry and mechanism is necessary. Thus, this review focuses primarily on understanding the effect of surfactants and the mechanism of desorption of PAHs from the soil. This work also emphasizes the effect of surfactants on the efficiency of mycoremediation of contaminated soil. Further, the review summarizes various surfactant-assisted mycoremediation strategies of contaminated soil. Finally, the limitations of surfactant-assisted mycoremediation, precipitative, and partitioning loss, along with toxicity of the surfactants, were reviewed. Thus, this review will aid in understanding the underlying mechanism and efficiency of surfactant-assisted mycoremediation and it also proposes current research trends to improve the efficiency and enhance the bioremediation of PAHs-contaminated soil.
