Modulating Surfactin Biosynthesis in Bacillus subtilis R31 Enhances Behavioural Traits and Biocontrol Efficacy Against Banana Fusarium Wilt. [PDF]

Microb Biotechnol
This study demonstrates that the production of surfactin by B. subtilis R31 needs to be balanced. Excessive surfactin will weaken the colonisation ability and disease control effect of the strain. By targeting the regulation of the surfactin signalling pathway, synthetic microbial communities can be designed for sustainable disease control.

Surfactin Facilitates Horizontal Gene Transfer in Bacillus subtilis [PDF]

Frontiers in Microbiology, 2021
Genetic competence for the uptake and integration of extracellular DNA is a key process in horizontal gene transfer (HGT), one of the most powerful forces driving the evolution of bacteria. In several species, development of genetic competence is coupled with cell lysis.

Anticancer Activities of Surfactin and Potential Application of Nanotechnology Assisted Surfactin Delivery [PDF]

Frontiers in Pharmacology, 2017
ثبت أن السطحي، وهو خافض حيوي دوري للببتيد الدهني تنتجه سلالات مختلفة من جنس العصوية، يحفز السمية الخلوية ضد العديد من أنواع السرطان، مثل استسقاء إرليخ وسرطان الثدي والقولون وسرطان الدم والورم الكبدي. يمكن للعلاج بالسطح أن يمنع تطور السرطان عن طريق تثبيط النمو، وتوقف دورة الخلية، والاستماتة، وتوقف النقائل. نظرًا للتأثير القوي للسطح على الخلايا السرطانية،

Surfactin and surfactin-like production, purification, and application at marine environments

, 2022
Surfactin, a biosurfactant with great activity on interfaces, have been reported as a great substitute to non-renewable sources, non-biologically synthesized surfactants. It is expected to see more studies at the next years evolving its application, including on marine environments, especially ones impacted with petroleum or other contaminants. In this

Isolation and characterization of a new variant of surfactin, the [Val7]surfactin [PDF]

European Journal of Biochemistry, 1991
Reinvestigation of surfactin, a previously studied peptidolipid surfactant from Bacillus subtilis, by fast‐atom‐bombardment mass spectrometry and 1H‐NMR spectroscopy, as well as by chemical methods, revealed the presence of a closely related second constituent. This new compound, [Val7]surfactin, differs from the known surfactin by the C‐terminal amino

Enrichment and Isolation of Surfactin-degrading Bacteria

Journal of Oleo Science, 2021
A total of 100 environmental samples were investigated for their ability to degrade 1 g/L surfactin as a substrate. Among them, two enrichment cultures, which exhibited microbial growth as well as surfactin degradation, were selected and further investigated.

Crystal Structure of the Surfactin Synthetase Termination Module

, 2012
Nichtribosomale Peptidsynthetasen (NRPS) zeigen, trotz der hohen Anzahl ihrer Bausteine und der somit großen Vielfalt ihrer Produkte, eine konstante strukturelle Verwandtschaft. Die NRPS‐Systeme sind modular aufgebaut, wobei definierte Domänen die einzelnen Reaktionen katalysieren.

Surfactins in Natto: The Surfactin Production Capacity of the Starter Strains and the Actual Surfactin Contents in the Products

Journal of Food Protection, 2014
Surfactin-type lipopeptides are suspected of being implicated in the rare food poisonings caused by Bacillus species outside the Bacillus cereus cluster. In order to get information on surfactin levels in actual human foods, bacilli from three commercial samples of a Japanese traditional bean product, natto, were isolated in order to clarify their ...

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.

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 ...
