Rhamnolipid Independent Swarming of Pseudomonas aeruginosa

, 2012
Swarming is a surface-associated motility where bacteria spread in groups, often as a precursor to biofilm formation. The bacterium Pseudomonas aeruginosa is known to swarm using its polar flagellum and a self-produced surfactant called rhamnolipid ...

Potential for Waste Reduction in Activated Sludge Systems: Evaluation of the Initial Conditions of a Rapid Test with Rhamnolipid Biosurfactant

Journal of Sustainable Development of Energy, Water and Environment Systems, 2019
Adding chemicals that alter the microbial metabolism and reduce cell growth, without affecting organic matter removal, is an alternative technology to reduce sludge production. This study was intended to determine the best initial conditions to conduct a

Stimulation of rhamnolipid biosurfactants production in Pseudomonas aeruginosa AK6U by organosulfur compounds provided as sulfur sources

Biotechnology Reports, 2015
A Pseudomonas aeruginosa AK6U strain produced rhamnolipid biosurfactants to variable extents when grown on MgSO4 or organosulfur compounds as sulfur sources and glucose as a carbon source. Organosulfur cultures produced much higher biosurfactants amounts

Imaging and Analysis of Pseudomonas aeruginosa Swarming and Rhamnolipid Production

, 2011
Many bacteria spread over surfaces by “swarming” in groups. A problem for scientists who study swarming is the acquisition of statistically significant data that distinguish two observations or detail the temporal patterns and two-dimensional ...

Efficient Dye Removal from Aqueous Solutions Using Rhamnolipid Biosurfactants by Foam Flotation [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2019
Methylene blue was efficiently removed from aqueous solution by foam flotation using a rhamnolipid biosurfactant as a dye collector. The effects of four parameters, namely, pH (1.5–11.5), frother concentration (5–65 ppm), aeration rate (2–6 L/min) and ...

Quorum sensing as a potential target for increased production of rhamnolipid biosurfactant in Burkholderia thailandensis E264 [PDF]

, 2019
Burkholderia thailandensis E264 is a potential non-pathogenic substitute for producing rhamnolipid biosurfactant, replacing the pathogenic Pseudomonas aeruginosa. However, it has low rhamnolipid production and longer fermentation time.

Engineering Bacteria for Production of Rhamnolipid as an Agent for Enhanced Oil Recovery

, 2007
Rhamnolipid as a potent natural biosurfactant has a wide range of potential applications, including enhanced oil recovery (EOR), biodegradation, and bioremediation. Rhamnolipid is composed of rhamnose sugar molecule and β-hydroxyalkanoic acid.
