Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Production of Lipopeptide Biosurfactant by a Hydrocarbon-Degrading Antarctic Rhodococcus

“…To date, only two studies have recorded the synthesis of lipopeptides from the Rhodococcus sp. [ 15 , 16 ]. Interestingly, a minor yet critical resemblance was detected to the report of Peng et al [ 15 ] where no precipitate was produced using the acid precipitation method towards the culture supernatant.…”

“…Rhodococcus biosurfactants are largely cell-bound glycolipids with the generic link of trehalose sugar, commonly known as trehalolipid [ 13 , 14 ]. Hence, the discovery of an unusual production of a lipopeptide in the course of this study was intriguing although novel lipopeptide from this genus has been reported twice [ 15 , 16 ]. Studies have reported that the polar microbial diversity is much richer than previously thought, comprising a number of prominent producers of bioactive natural products such as Actinobacteria and Proteobacteria with advanced and novel survival machinery [ 17 , 18 ].…”

Biosurfactants: Production and application prospects in the food industry

“…46,47 Other characteristics of interest are also reported, such as antiviral, anticarcinogenic and immunomodulating activities. 48,49 All of these properties favor biosurfactants for applications hitherto little explored, which are increasingly being the object of promising studies. 50…”

“…Besides the reduction in surface and interfacial tensions and the formation and stabilization of emulsions, biosurfactants also have other properties and biological functions, such as the solubilization of hydrophobic compounds 42,43 and the removal of heavy metals 44,45 as well as antibiofilm, antioxidant and antimicrobial properties 46,47 . Other characteristics of interest are also reported, such as antiviral, anticarcinogenic and immunomodulating activities 48,49 . All of these properties favor biosurfactants for applications hitherto little explored, which are increasingly being the object of promising studies 50 …”

Motor oil wastewater treatment in a packed bed bioreactor using immobilized native microbial consortium

“…Bioremediation is considered an efficient, costeffective, and eco-friendly method to degrade hydrocarbons in petroleum-contaminated soil and water (Wu et al, 2017;Xu et al, 2018;Bhattacharya et al, 2019;Interiano-López et al, 2019;Yalaoui-Guellal et al, 2020). Biodegradation by indigenous microorganisms is a major mechanism and a reliable method that operates by biologically removing toxic compounds such as hydrocarbons, petroleum, and its derivates (Al-Hawash et al, 2018;Sonwani et al, 2020;Tao et al, 2020).…”
