Enhanced rhamnolipids production using a novel bioreactor system based on integrated foam-control and repeated fed-batch fermentation strategy

Biotechnology for Biofuels, 2020
Background Rhamnolipids are the best known microbial-derived biosurfactants, which has attracted great interest as potential ‘‘green” alternative for synthetic surfactants.

Biofilm as a production platform for heterologous production of rhamnolipids by the non‑pathogenic strain Pseudomonas putida KT2440 [PDF]

, 2016
BACKGROUND: Although a transition toward sustainable production of chemicals is needed, the physiochemical properties of certain biochemicals such as biosurfactants make them challenging to produce in conventional bioreactor systems.

Microbial production of rhamnolipids: opportunities, challenges and strategies

Microbial Cell Factories, 2017
Rhamnolipids are a class of biosurfactants which contain rhamnose as the sugar moiety linked to β-hydroxylated fatty acid chains. Rhamnolipids can be widely applied in many industries including petroleum, food, agriculture and bioremediation etc ...

The Synergistic Activity of Rhamnolipid Combined with Linezolid against Linezolid-Resistant Enterococcus faecium

Molecules, 2023
Enterococci resistance is increasing sharply, which poses a serious threat to public health. Rhamnolipids are a kind of amphiphilic compound used for its bioactivities, while the combination of nontraditional drugs to restore linezolid activity is an ...

Effect of biosurfactants on Pseudomonas aeruginosa and Staphylococcus aureus biofilms in a BioFlux channel. [PDF]

, 2016
Recent studies have indicated that biosurfactants play a role both in maintaining channels between multicellular structures in biofilms and in dispersal of cells from biofilms. A combination of caprylic acid (0.01 % v/v) together with rhamnolipids (0.04 %

Disruption of Yarrowia lipolytica biofilms by rhamnolipid biosurfactant [PDF]

, 2012
BACKGROUND: Yarrowia lipolytica is an ascomycetous dimorphic fungus that exhibits biofilm mode of growth. Earlier work has shown that biosurfactants such as rhamnolipids are efficient dispersants of bacterial biofilms.

Modeling downstream impact of a quorum sensing system of Pseudomonas aeruginosa in colony spreading

Partial Differential Equations in Applied Mathematics, 2023
A single bacterial colony typically consists of two or more individual cells. To further growth, the cells within the colony need to coordinate through Quorum Sensing (QS), which serves as a communication mechanism between cells.
