“…Potential trehalolipids producers are Mycobacterium, Corynebacterium, Nocardia, Rhodococcus erythropolis, and Arthrobacter sp., and their structure differs premised on the microbial source (Srivastava et al 2021). On account of their surface-active properties, they are implemented in oil recovery and bioremediation strategies (Hassan et al 2021). Furthermore, they have biological activity favoring them in biomedical applications (O'Neill et al 2017).…”

“…This process is accelerated by centrifugation. For rhamnolipids, phase separation can be carried out using various methods such as distillation, solid-liquid extraction, sweep floc coagulation, and liquid-liquid extraction (Demling et al 2020;Hassan et al 2021). In sweep floc coagulation, the suspended particles are firstly neutralized and then are aggregated into flocs, improving their sedimentation efficiency (Shen et al 2019).…”

Microbial biosurfactants are sustainable alternatives for synthetic counterparts, and display high biodegradability, environmental compatibility, and high selectivity. While previous reports have focussed on production yield, little attention has been paid on downstream processing of biosurfactants, a critical step that controls quality. Here we review methods for biosurfactant downstream processing with focus on glycolipids and lipopeptidesglycolipids and lipopeptides. Solvent extraction, foam fractionation, and sweep floc coagulation allow to reach a purity of 55-70%. While distillation can be implemented prematurely, methods like ultrafiltration and chromatography are used as final processing to recover 90-95% of biosurfactant with 78-95% of purity. We present the cheapest and most efficient downstream techniques for industries to achieve acceptable product quality. This paper puts forth the environmental applications of biosurfactants. We review applications in treating hydrophobic organic pollutants and heavy metals in soils and water. The removal efficiency of biosurfactants reaches 96%. Biosurfactants in the detergent industry, microbial enhanced oil recovery, and soil washing are also discussed.

“…This has led to the development of several pesticide analysis approaches for sample preparation 6–8 and analysis techniques. 6,9,10 Based on the chromatographic methods, volatile pesticides and less/non-volatile pesticides have been conventionally separated by gas chromatography (GC) and liquid chromatography (LC), respectively, such as the determination of organophosphorus pesticides in cabbage by GC coupled with flame ionization detection (FID), 11 and the quantification of pyrethroid residues in seafood by LC equipped with a photodiode array detector. 12 For the compounds detectable with both approaches with similar limits of detection, GC is preferred due to the general advantages of higher resolution and less solvent consumption.…”

“…Various sample preparation methods were applied for the determination of pesticides in cabbage before GC analysis. The recent applications included dispersive trehalose biosurfactant-enhanced magnetic solid phase extraction (SPE), 11 dispersive SPE using microporous metal–organic framework UiO-66, 33 and liquid–solid extraction coupled with magnetic solid phase extraction based on polystyrene-coated magnetic nanoparticles. 34 Alternatively, QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) has been effectively applied with the cabbage sample matrices.…”

“…Additionally, large‐scale fractionation of barley polyphenols was performed by reversed‐phase flash extraction (Gangopadhyay et al ., 2016). However, these organic solvents are commonly toxic and regarded as unsafe for food processing (Hassan et al ., 2021). Thus, a gradient elution method, with different ethanol‐water concentrations, was proposed for the extraction of multiple classes of polyphenols in complex botanical extracts such as honeybush for food applications.…”

The structural diversity of polyphenols and the inherent limitations of current extraction techniques pose a challenge to extract polyphenols using a simple and green method. Hence, in this study, a method was developed to simultaneously fractionate multiple classes of polyphenols by only varying ethanol-water solutions. Honeybush tea, which is rich in polyphenols, was selected as a model for this study. Solvent extraction followed by solid-phase extraction (SPE) was developed to obtain a polyphenol-rich fraction from six honeybush samples. Based on a gradient elution programme (10%, 30%, 50%, 70% and 90% (v/v) ethanol-water solution) of SPE, the Strata X cartridge showed a better recovery of most targeted polyphenols under 0.9 mL of the drying volume and 1 mL min −1 of the dispensing speed. The elution programme for fractionating most polyphenols was as follows: single elution with 50% ethanol, followed by twice elution with 70% ethanol. The antioxidant capacity was used to analyse the differences among the polyphenol-rich fractions from six honeybush samples. Principal component analysis (PCA) revealed that unfermented C. genistoides (GG) has the greatest antioxidant capacity among the honeybush species studied. Additionally, mangiferin, isomangiferin and vicenin-2 were the main contributors to the antioxidant capacity in six honeybush fractions according to the correlation study.
