The use of natural and environmentally-friendly antimicrobials is a growing trend in several industrial sectors, including the food area. Ramnolipids (RL), surfactants of microbial origin, have been showing potential for control of food pathogens and are considered "green surfactants" fulfilling the current market demand. In a recent study, it was evidenced that RL have potential for con…
The use of natural and environmental-friendly antimicrobials represent a trend in the food industry. The rhamnolipids, microbial-derived surfactants, have shown potential as agents to control the growth of food pathogens additionally; they have gained the status of ´green surfactants'. Chitosan is a biopolymer of recognized antimicrobial activity, which is soluble under acidic conditio…
Rhamnolipids (RL) are bacterial-derived surfactants showing very interesting properties to food industry not only as emulsifier agents but also due to their biodegradability, low toxicity and production using renewable substrates. The RL show potential on controlling microorganisms exhibiting antimicrobial activity and decreasing biofilm formation of food pathogens as Listeria monocytoge…
When growing in biofilms microrganisms are more resistant to agents as antibiotics and disinfectants. Despite the great availability of antimicrobial compounds, there is a lack of molecules that are effective on controlling biofilms. Many biofilm-forming bacteria are related to diseases such as cystic fibrosis ( Pseudomonas aeruginosa) and tooth decay ( Streptococcus mutans) thus, the …

The aim of this project is to verify the antimicrobial activity of rhamnolipid biosurfactants against Listeria monocytogenes isolates. Six bacterial isolates will be tested against 3 rhamnolipid samples obtained from different cultures of P. aeruginosa. The antimicrobial activity will be evaluated by broth microdilution technique to determine the minimal inhibitory concentration of each a…
The growing environmental awareness of the population, combined with the requirements of legislation, encouraging industry to search for products less aggressive to health and environment. The rhamnolipids (RL) are a class of microbial surfactants which have properties of interest to the food industry not only because of their intrinsic characteristics, but also for their environmental-fr…
