A soil microorganism identified as Bacillum megaterium was found to produce several antibiotics substances after growth for 20 h at 37°C in a mineral culture medium. Analysis both by electron spray ionization (ESI) and matrix-assisted laser desorption ionization—time of flight (MALDI-TOF) mass spectrometry (MS) identified these substances as lipopeptides. Predominant peaks at m/z 1,041 and m/z 1,065 revealed ions which are compatible with surfactins and lichenysins, respectively. Two other ions…

Purification and structural characterization of fengycin homologues produced by Bacillus subtilis LSFM-05 grown on raw glycerol
TLDR
Results demonstrate that raw glycerol can be used as feedstock to produce fengycin, and additional work should focus on the optimization of process conditions to increase productivity.
Marine Bacterium Derived Lipopeptides: Characterization and Cytotoxic Activity Against Cancer Cell Lines
TLDR
A marine Bacillus circulans DMS-2 was able to grow and produce biosurfactant on glucose mineral salts medium with a reduction in the surface tension up to 27 mN m−1 and the identity of the produced lipopeptides as surfactin and fengycin isoforms was revealed.
Characterization of Novel Lipopeptides Produced by Bacillus tequilensis P15 Using Liquid Chromatography Coupled Electron Spray Ionization Tandem Mass Spectrometry (LC–ESI–MS/MS)
Microbes are known to interact and communicate with their neighbouring cells by releasing diverse types of low molecular weight diffusible metabolites. This paper describes the identification of
Lipopeptides from the Banyan Endophyte, Bacillus subtilis K1: Mass Spectrometric Characterization of a Library of Fengycins
TLDR
Mass spectrometric analysis of a banyan endophyte, Bacillus subtilis K1, extract revealed a complex mixture of lipopeptides, iturins, surfactins, and fengycins, where four major sites of heterogeneity are identified.
The Self-Assembly of a Cyclic Lipopeptides Mixture Secreted by a B. megaterium Strain and Its Implications on Activity against a Sensitive Bacillus Species
Cyclic lipopeptides are produced by a soil Bacillus megaterium strain and several other Bacillus species. In this work, they are detected both in the Bacillus intact cells and the cells culture
Simultaneous Production of Antibacterial Protein and Lipopeptides in Bacillus tequilensis, Detected by MALDI-TOF and GC Mass Analyses
TLDR
The anticancer and antibacterial properties of B. tequilensis, along with its non-toxicity and stability, have made it a potential candidate for studying the beneficial probiotic properties for humans and drug production.
Isolation and partial characterization of antibacterial lipopeptide produced by Paenibacillus polymyxa HKA-15 against phytopathogen Xanthomonas campestris pv. phaseoli M-5
TLDR
The characterization of the antibacterial compound revealed its lipopeptide nature, being able to inhibit the growth of the fungal pathogen, Rhizoctonia bataticola, Macrophomina phaseolina and Fusarium udum and a stronger inhibition was observed against bacterial pathogens.
Isolation and characterization of antifungal lipopeptides produced by endophytic Bacillus amyloliquefaciens TF 28
Bacillus amyloliquefaciens TF28, an endophytic bacterium isolated from soybean root, showed strong antifungal activity in vitro. In this study, crude lipopeptides were extracted with methanol from
Isolation and characterization of antifungal lipopeptides produced by endophytic Bacillus amyloliquefaciens TF28
TLDR
Crude lipopeptides extracted with methanol from the precipitate by adding concentrated HCl to culture filtrate exhibited highest antifungal activity against the rice bakanae fungus Fusarium moniliforme, and is a candidate biocontrol agent for rice bAKanae controlling.

TLDR
This study studied the effects of different media on the nature of the synthesis of fatty acid chains for each lipopeptide family and found that the intensity of production of homologous compounds depends on the strain and the culture medium.
