The anti-thrombotic activity of surfactins

Journal of Veterinary Science, 2005
Platelet aggregation was inhibited and the density of platelet-rich plasma (PRP) clots was decreased by the preincubation of PRP with surfactins, an acidic lipopeptide of Bacillus subtilis complex BC1212 isolated from soybean paste, in dose-dependent manner.

Surfactin Isoforms from Bacillus coagulans

Zeitschrift für Naturforschung C, 2006
Abstract Bacillus coagulans has been found to produce several surfactins that are powerful lipopeptide surfactants. Four main components with molecular weights 1007, 1021 and 1035 Da were separated. Their structures have been confirmed by spectrometric and spectroscopic studies and by acid hydrolysis.

Interaction of Surfactin with Membranes: A Computational Approach

Langmuir, 2003
Modeling analysis was used to understand the molecular mechanisms of the biological activities of surfactin, in particular, its hemolytic activity. This study highlights the importance of the fatty acid chain hydrophobicity of the surfactin on its activities, the C15 homologue being the most active. This is related to its self-association capacity. The

Surfactin C inhibits platelet aggregation

Journal of Pharmacy and Pharmacology, 2006
Abstract This study was designed to investigate the effect of surfactin C, which is derived from Bacillus subtilis, on platelet aggregation and homotypic leucocyte aggregation. Surfactin C strongly and dose-dependently inhibited platelet aggregation, which was stimulated both by thrombin (0.1 U mL−1), a potent agonist that activates the ...

Infrared Nanospectroscopy of Phospholipid and Surfactin Monolayer Domains [PDF]

ACS Omega, 2018
A main challenge in understanding the structure of a cell membrane and its interactions with drugs is the ability to chemically study the different molecular species on the nanoscale. We have achieved this for a model system consisting of mixed monolayers (MLs) of the biologically relevant phospholipid 1,2-distearoyl-sn-glycero-phosphatidylcholine and ...

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

Advanced Science, EarlyView.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

A study on the interactions of surfactin with phospholipid vesicles

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1999
Surfactin, an acidic lipopeptide produced by various strains of Bacillus subtilis, behaves as a very powerful biosurfactant and posses several other interesting biological activities. By means of differential scanning calorimetry and X-ray diffraction the effect of surfactin on the phase transition properties of bilayers composed of different ...

Available strategies for improving the biosynthesis of surfactin: a review

Critical Reviews in Biotechnology, 2022
Surfactin is an excellent biosurfactant with a wide range of application prospects in many industrial fields. However, its low productivity and high cost have largely limited its commercial applications. In this review, the pathways for surfactin synthesis in Bacillus strains are summarized and discussed.

Understanding the Aqueous Self‐Assembly of Raw Sophorolipid Mixtures Using a Statistical Approach Applied to Synchrotron Small Angle X‐Ray Scattering (SAXS): A Focus on pH, Dilution, Aging, and the Underestimated Role of Residual Fatty Acids

Journal of the American Oil Chemists' Society, EarlyView.
The statistical analysis of SAXS modelling data allows to identify the critical physicochemical parameters that have an impact on the phase behavior of crude sophorolipid batches. ABSTRACT The aqueous self‐assembly of raw sophorolipid mixtures has been studied by small angle x‐ray scattering (SAXS) to understand the impact of the composition ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

Biotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.
