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.

New Linear Lipopeptides Produced by Pseudomonas cichorii SF1-54 Are Involved in Virulence, Swarming Motility, and Biofilm Formation

open access: yesMolecular Plant-Microbe Interactions, 2013
Pseudomonas cichorii is the causal agent of lettuce midrib rot, characterized by a dark-brown to green-black discoloration of the midrib. Formation of necrotic lesions by several plant-pathogenic pseudomonads is associated with production of phytotoxic ...

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.

Synthèse et auto-organisation de lipopeptides organocatalytiques bio-inspirés : influence de l'agrégation sur leur activité hydrolytique [PDF]

open access: yes, 2015
Enzymes are proteins with remarkable catalytic properties but their stability and availability may sometimes become a limitation to their use. This is why simpler, cheaper and more tunable catalytic systems are developed in the meantime.

Ion mobility mass spectrometry for lipopeptides analysis

open access: yes, 2019
Cyclic lipopeptides (CLPs) are produced by bacteria in a ribosome independent manner and consists in a hydrophilic peptide linked to a B-hydroxy fatty acid chain.

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.
