Genotoxicity of cationic lipopeptide nanoparticles

Toxicology Letters, 2020
The genotoxicity of cationic lipopeptide nanoparticles (cLPNPs) was evaluated in vivo and in vitro comet assay and the in vivo chromosome aberrations test. In vitro comet assay, human blood cells were exposed to cLPNPs at the concentration of 2.5, 5, 10, 20, 40 and 100 μg/mL.

In Vitro and Ex Vivo Antibiofilm Activity of a Lipopeptide Biosurfactant Produced by the Entomopathogenic Beauveria bassiana Strain against Microsporum canis

Microorganisms, 2020
Microsporum canis is one of the most important dermatophyte causing tinea corporis and tinea capitis and its biofilm-form has a poor therapeutic response. The biosurfactant production by entomopathogenic fungi (EPF) has not been reported yet.

Quantification of FEND and ITUDI Anti-fungal Lipopeptide Gene Expression in Bacillus megaterium using RT-qPCR

, 2020
Phytopathogenic diseases are a major concern in modern agriculture, and for decades, pesticides have been used to prevent potential damage. Bacillus megaterium is proposed as a biological controlling agent, and gene expression of the lipopeptide genes ...

ANTIMICROBIAL ACTIVITY OF LIPOPEPTIDES [PDF]

Postępy Mikrobiologii - Advancements of Microbiology, 2018
Abstract The constantly growing number of multidrug-resistant bacterial strains prompts the search for alternative treatments. Synthetic peptides based on natural antimicrobial peptides, also known as antimicrobial lipopeptides, can become a promising group of “drugs” to fight multi-resistant bacteria.

An Economical Bioprocess for Lipopeptide Production From Bacillus subtilis. [PDF]

Microbiologyopen
The lipopeptide (LP) production potential of Bacillus isolates was evaluated against phytopathogenic fungi, with B. subtilis 4‐Ka‐22 identified as the top‐performing strain. Optimization of the production medium—comprising molasses, soybean meal, CaCl2, and glycerol—resulted in a 13.4‐fold increase in cell growth and over 99% cost reduction compared to

Regulation of cyclic lipopeptide biosynthesis in Pseudomonas fluorescens by the ClpP protease

, 2009
Cyclic lipopeptides produced by Pseudomonas species exhibit potent surfactant and broad-spectrum antibiotic properties. Their biosynthesis is governed by large multimodular nonribosomal peptide synthetases, but little is known about the genetic ...

The interplay between daptomycin and the immune system

Frontiers in Immunology, 2014
Antibiotics may have bacteriostatic or bactericidal effects but may also cause immunomodulation. Lipopeptides are known immunomodulators that interact with pattern recognition receptors (PRRs) such as Toll-like receptors (TLRs) in antigen presenting ...
