“… 35 It is convenient to screen surfactin-producing strains by the change in color, but the quantitative accuracy of this method is not very good. Other methods or techniques have also been employed to estimate the yields of biosurfactants during screening strains producing biosurfactants through Fourier Transform Infrared (FT-IR) spectroscopy, 36 hemolytic activity 37 or interfacial tension tests. However, these methods are not suitable for rapid and accurate quantification of biosurfactants due to the complexity of the process or inconvenient calibration.…”

“…Fourier transform infrared spectrometry is a prominent method used in assessing non-ionic surfactants (Gartshore et al 2000;Carolei and Gutz 2005). Here, the non-ionic surfactants must be extracted and concentrated through the salting-out procedure (Andrew 1993).…”

This work comprehensively reviewed the toxicity and risks of various surfactants and their degraded products in the environmental matrices, various analytical procedures, and remediation methods for these surfactants. The findings revealed that the elevated concentration of surfactants and their degraded products disrupt microbial dynamics and their important biogeochemical processes, hinder plant-surviving processes and their ecological niche, and retard the human organic and systemic functionalities. The enormous adverse effects of surfactants on health and the environment necessitate the need to develop, select, and advance the various analytical and assessment techniques to achieve effective identification and quantification of several surfactants in different environmental matrices. Considering the presence of surfactants in trace concentration and environmental matrices, excellent analysis can only be achieved with appropriate extraction, purification, and preconcentration. Despite these pre-treatment procedures, the chromatographic technique is the preferred analytical technique considering its advancement and shortcomings of other techniques. In the literature, the choice or selection of remediation techniques for surfactants depends largely on eco-friendliness, cost-implications, energy requirements, regeneration potential, and generated sludge composition and volume. Hence, the applications of foam fractionation, electrochemical advanced oxidation processes, thermophilic aerobic membranes reactors, and advanced adsorbents are impressive in the clean-up of the surfactants in the environment. This article presents a compendium of knowledge on environmental toxicity and risks, analytical techniques, and remediation methods of surfactants as a guide for policymakers and researchers.

High molecular weight polycyclic aromatic hydrocarbons (HMW PAHs) increase in hydrophobicity with increases in their molecular weight and ring angularity. Microbial strategies to deal with PAH hydrophobicity include biofilm formation, enzyme induction, and biosurfactants, the effect of which is variable on PAH metabolism depending on the surfactant type and concentration, substrate, and microbial strain(s). Aerobic HMW PAH metabolism proceeds via mineralization, partial degradation, and cometabolic transformations. Generally, bacteria and nonlignolytic fungi metabolize PAHs via initial PAH ring oxidation by dioxygenases to form cis-dihydrodiols, which are transformed to catechol compounds by dehydrogenases and other mono-and dioxygenases to substituted catechol and noncatechol compounds, all ortho-or metacleaved and further oxidized to simpler compounds. However, lignolytic fungi form quinones and acids to CO 2 . This review discusses the pathways for HMW PAH microbial metabolism. O
