Surfactants are widely used in many areas of our life. However, synthetic surfactants have a serious negative impact on the environment. They do not decompose well and can accumulate ecosystems. Microbial biosurfactants be an alternative to surfactants. characterized by diverse structure, stable at critical temperatures, pH obtained from various renewable raw materials. Goal: analysis generaliz...

A Pseudomonas aeruginosa mutant derived by random mutagenesis with N-methyl-N¢-nitro-N-nitrosoguanidine, producing high levels of the rhamnolipid biosurfactants was selected on Siegmund-Wagner (SW) plates. The mutant designated P. aeruginosa PTCC1637 produces rhamnolipids at concentrations 10 time more than parent strain. NMR analysis and surface tension measurement showed that the biosurfactan...

The interactions between bacterial species during infection can have significant impacts on pathogenesis. Pseudomonas aeruginosa and Staphylococcus aureus are opportunistic pathogens that co-infect hosts cause serious illness. factors dictate whether one outcompetes the other or two coexist not fully understood. We investigated role of surfactants in these a surface enables P. to swarm. found s...
