Microbial biosurfactants are low-molecular-weight surface-active compounds of high industrial interest owing to their chemical properties and stability under several environmental conditions. The chemistry a biosurfactant its production cost defined by the selection producer microorganism, type substrate, purification strategy. Recently, have been applied solve or contribute solving some problems, with this being main field application. most referenced studies based on bioremediation contaminated soils recalcitrant pollutants, such as hydrocarbons heavy metals. In case metals, function chelating agents binding capacity. However, mechanism which typically act in an is focused ability reduce surface tension, thus facilitating emulsification solubilization certain pollutants (in-situ biostimulation and/or bioaugmentation). Moreover, despite low toxicity biosurfactants, they can also biocidal at doses, mainly higher concentrations than critical micellar concentration. More recently, using alternative substrates, types organic waste solid-state fermentation, has increased applicability research circular economy context. review, recent publications use applications conventional surfactants summarized analyzed.

Green Electrospinning of Biodegradable Cellulose Acetate Nanofibrous Membranes with Tunable Porosity

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(3), P. 994 - 1005

Published: Jan. 9, 2023

The electrospinning of polymer nanofibers has received significant attention owing to their high surface-area-to-volume ratio, porosity, adjustable pore size and texture, highly interconnected porous structure. In particular, the biodegradable cellulose acetate (CA) sparked interest in diverse applications, including drug delivery systems, scaffolding for tissue engineering, air filtration, affinity membrane systems. However, process been mostly performed using toxic hazardous solvents additives. We developed electrospun CA a green solvent system comprising dimethyl carbonate cyclopentanone. use additives, namely, tetrabutylammonium bromide salts sophorolipid-based biosurfactants, obtained from honey yeast, substantially improved spinnability solution. Moreover, nanofiber diameter texture were tunable by adjusting ratio. Pore generation was induced volatile carbonate, which quickly evaporated fiber jet. Molecular dynamics simulations demonstrated that can be divided into three stages. addition biosurfactant facilitated evaporation uniformity nanofibers. Furthermore, degraded esterase cellulase enzymes. To summarize, ultrafine with morphology achieved

Updated component analysis method for naturally occurring sophorolipids from Starmerella bombicola

Applied Microbiology and Biotechnology, Journal Year: 2024, Volume and Issue: 108(1)

Published: April 12, 2024

Abstract Sophorolipids (SLs) are promising glycolipid biosurfactants as they easily produced and functional. SLs from microorganisms comprised of mixtures multiple derivatives that have different structures properties, including well-known acidic lactonic SL (ASLs LSLs, respectively). In this study, we established a method for analyzing all in the products Starmerella bombicola , typical SL-producing yeast. Detailed component analyses S. were carried out using reversed-phase high-performance liquid chromatography mass spectrometry. Methanol was used eluent it is good solvent derivatives. With approach, possible to not only quantify ratio main components ASL, LSL, glycerides but also confirm trace such mono-glyceride bola-form (sophorose at both ends); notably, first time these been isolated identified successfully naturally occurring SLs. addition, our results revealed novel derivative which fatty acid bonded series had reported previously. Using present analysis method, track compositional changes during culture. Our showed LSL ASL initially accumulate middle stage fermentation process.
