Broad antibiosis activity of Bacillus velezensis and Bacillus subtilis is accounted for by a conserved capacity for lipopeptide biosynthesis

open access: yesFrontiers in Microbiology
We evaluated 284 strains from 15 species across five genera in the Phylum Bacillota (Bacillus, Priestia, Cytobacillus, Neobacillus, and Gottfriedia) for antibiosis activity against the pathogenic oomycete, Phytophthora nicotianae.

The Preparation of Novel Fluorenes Inspired by Hipposudoric Acid

open access: yesHelvetica Chimica Acta, EarlyView.
In this research we report on the design and synthesis of a series of fluorene‐based derivatives loosely inspired by the tricyclic framework of hipposudoric acid. Preparation of sixteen novel N‐alkylated derivatives was accomplished via a series of concise one‐step amide N‐alkylation reactions.

Crystal structure of the TLR1-TLR2 heterodimer induced by binding of a tri-acylated lipopeptide [PDF]

open access: yes, 2007
TLR2 in association with TLR1 or TLR6 plays an important role in the innate immune response by recognizing microbial lipoproteins and lipopeptides. Here we present the crystal structures of the human TLR1- TLR2- lipopeptide complex and of the mouse TLR2-

Biosurfactant‐assisted recovery and remediation of hydrocarbons from oily sludge using a mobile aerated washing system

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The oil industry generates oily sludge, the accumulation of which poses a serious environmental problem. Conventional methods require high costs, specialized equipment, and qualified personnel. This waste can be treated using biosurfactants.

Micellar and Solubilization Properties of Biological Surfactant Surfactin

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.

Ultrashort antibacterial and antifungal lipopeptides [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Host-defense cationic antimicrobial peptides (≈12–50 aa long) play an essential protective role in the innate immune system of all organisms. Lipopeptides, however, are produced only in bacteria and fungi during cultivation, and they are composed of specific lipophilic moieties attached to anionic peptides (six to seven amino acids)

Biosurfactant Production From Waste Frying Oil: Process Optimization and Physicochemical Characterization of Surface Properties

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT This study focuses on the development of a cost‐effective bioprocess for biosurfactant production, encompassing process optimization and physicochemical characterization. Surface tension reduction and oil dispersion activity were evaluated, highlighting its strong potential for applications in food, pharmaceuticals, and bioremediation. In this
