“…Optimizing the fermentation conditions involves selection of the optimal culture conditions that will induce the maximum productivity. A number of factors have been reported to affect RL production including the nature of the carbon source, temperature, agitation rate and pH [9]. Although a considerable number of studies on the optimization of RL production have been reported recently [10][11][12], more studies are still required to find and optimize new promising isolates producing this powerful biosurfactant.…”

Rhamnolipids are interesting microbial surfactants having great industrial importance. However, the main obstacles towards an economic production of rhamnolipids are low productivity and high raw‐material costs. Therefore, this study aimed at optimization of the culture media as well as culture conditions using response surface methodology for maximum rhamnolipid production by Pseudomonas aeruginosa isolate P6, a promising rhamnolipid‐producing isolate. The optimum medium for maximum rhamnolipid production was found to be a mineral salts medium with glycerol 2 % v/v as the carbon source. The optimum cultivation conditions using response surface methodology were found to be an incubation temperature of 30 °C, an agitation rate of 250 rpm, an inoculum size of 5 % v/v and unlike most studies, an initial pH of 7.5. The resulting model predicted data points that corresponded well to the experimental values. Optimization resulted in a threefold increase in rhamnolipid production reaching 7.54 g/L. The data are potentially useful for further industrial exploitation of rhamnolipid production by the studied isolate.

“…They produced by the bacterium Pseudomonas aeruginosa and are known as efficient anionic biosurfactant molecules . They are also used for a wide range of industrial applications, especially in food, cosmetics and pharmaceutical formulations as well as in bioremediation of pollutants . Rhamnolipids are applicable to a variety of pathogenic microorganisms especially for Gram‐positive bacteria, but it is difficult to correlate the bacteriotoxic activity to the properties of rhamnose or fatty acid.…”

It seems that the antimicrobial effects result from inhibition of pathogens metabolism, damage of plasma membranes and induction of fruit resistance such as relevant gene expression improvement.…”

“…From a biotechnological point of view, RLs are powerful biosurfactants with applications related to environmental concerns, such as bioremediation of hydrocarbon, organic pollutants and heavy-metal-contaminated sites. These topics have been extensively reviewed including some very recent articles [3–6]. RLs have also been used in the production of fine chemicals, surface coatings, as well as additives for food and cosmetics [7].…”

Rhamnolipids are known as very efficient biosurfactant molecules. They are used in a wide range of industrial applications including food, cosmetics, pharmaceutical formulations and bioremediation of pollutants. The present review provides an overview of the effect of rhamnolipids in animal and plant defense responses. We describe the current knowledge on the stimulation of plant and animal immunity by these molecules, as well as on their direct antimicrobial properties. Given their ecological acceptance owing to their low toxicity and biodegradability, rhamnolipids have the potential to be useful molecules in medicine and to be part of alternative strategies in order to reduce or replace pesticides in agriculture.
