The yeast Starmerella bombicola distinguishes itself from other yeasts by its potential of producing copious amounts the secondary metabolites sophorolipids (SLs): these are glycolipid biosurfactants composed out a(n) (acetylated) sophorose moiety and a lipid tail. Although SLs subject numerous research papers have been commercialized, e.g., in eco-friendly cleaning solutions, natural function still remains elusive. This article investigates several hypotheses for why S. invests that much energy production SLs, we conclude main is niche protection: (1) extracellular storage an energy-rich, yet metabolically less accessible carbon source can be utilized upon conditions starvation with (2) antimicrobial properties. In this way, creates dual advantage competition microorganisms. Additionally, expedite growth on rapeseed oil, triacylglycerols which hydrophobic substrates present yeasts' environment, non-SL strain (Δcyp52M1). It was also found that-at least under lab conditions-SLs do not provide protection against high osmotic pressure prevalent sugar-rich environments such as honey or nectar habitat bombicola.

Microbial biosurfactants have attracted the attention of researchers and companies for last decades, as they are considered promising candidates to replace chemical surfactants in numerous applications. Although years, considerable advances were performed regarding strain engineering use low-cost substrates order reduce their production costs, one main bottlenecks is at industrial scale. Conventional aerobic biosurfactant processes result excessive foaming, due high agitation aeration rates necessary increase dissolved oxygen concentration allow microbial growth production. Different approaches been studied overcome this problem, although with limited success. A not widely explored alternative development foam-free through anaerobic biosurfactant-producing microorganisms. Surfactin, produced by Bacillus subtilis, most lipopeptide biosurfactant, powerful known so far. licheniformis strains produce lichenysin, a which structure similar surfactin. However, despite its extraordinary surface-active properties potential applications, lichenysin has scarcely studied. According previous studies, B. better adapted than could be good biosurfactants. In review, limitations surfactin under conditions will analyzed, possibility implementing production, expand market applications different fields, discussed.

Biosurfactants with anti-inflammatory activity may alleviate skin irritation caused by synthetic surfactants in cleaning products. Sophorolipid (SL) is a promising alternative to surfactants. However, there are few reports on the of SL and underlying mechanism. The purpose this work verify that lipopolysaccharide (LPS)-induced inflammation could be inhibited through targeting pathway nuclear factor-κB (NF-κB) RAW264.7 cells.The influence cytokine release was investigated LPS-induced cells using ELISA. quantification protein expression corresponding molecular markers realized Western blot analysis. Flow cytometry employed determine levels Ca2+ reactive oxygen species (ROS). relative inducible nitric oxide synthase (INOS) cyclooxygenase-2 (COX-2) determined RT-PCR. An immunofluorescence assay confocal microscope were used observe NF-κB/p65 translocation from cytoplasm into nucleus. likely targets predicted docking analysis.SL showed reduced inflammatory cytokines including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), (NO). experimental results show suppressed ROS influx alleviated iNOS COX-2, NF-κB (p65) nucleus, phosphorylated proteins such as p65 IκBα. Furthermore, analysis inhibit signaling competing LPS bind TLR4/MD-2 hydrophobic interactions inhibiting IKKβ activation hydrogen bonding interactions.This study demonstrated exerted via cells.

Biofilm-associated lung infections, particularly those caused by Staphylococcus aureus (S. aureus), pose significant clinical challenges to conventional therapies. S. Biofilm infections are refractory treatment due the presence of persister bacterial cells and barrier effect unique extracellular polymeric substances (EPS). This study describes development multifunctional micelles, HK-SL Ms, utilizing sophorolipid (SL) encapsulate Honokiol (HK). Ms potently disrupted EPS barrier, killed some internal colonizing bacteria, inhibited further adhesion. Consequently, dynamic cycling biofilms was hindered, achieving a promising removal biofilms. In vitro studies demonstrated that exhibited antimicrobial reduction 6.42 log10CFU/mL. eradicated 71.73% targeting polysaccharides, proteins, viable within biofilm. Additionally, 1.66 log10CFU/mL units were killed. Moreover, 91.10% early biofilm formation obstructing initial adhesion polysaccharides polysaccharide intercellular adhesins (PIA). Thus, reestablishment reinfection could be resolved promisingly. as predominant in acute pneumonia chronic cases, inducing similar inflammation. murine model infected aureus, significantly reduced load lungs, decreased inflammatory factor levels, repaired tissue damage. offers novel strategy for biofilm-associated dispersing removing preventing new infections.
