Production of microbial glycolipid biosurfactants and their antimicrobial activity dan solaiman, rick ashby, jon zerkowski biosurfactant surface tension cmc γ . Study, the biosurfactant exhibited good antibacterial activity against tested pathogens and gram negative pathogens were highly susceptible this present study substantiates the antibacterial potential of biosurfactant produced by.
The antibacterial activity of biosurfactant was high against gram positive pathogenic bacteria than gram negative bacteria the rhamnolipid produced pseudomonas sp may be used as a tool to manage the oil pollution. The activity was shown to be directly related to the rhamnolipid concentration, highlighting the importance of maximising the biosurfactant yield when developing a process for the production of rhamnolipids as antimicrobial agents.

In the production of surfactin from bacillus sp - antibacterial activity of biosurfactant introduction , two types of bacillus subtilis strains were used in isolating the wanted lipopeptides surfactin fot this study.
29 antimicrobial activity: the antibacterial and antifungal activity of the extracted biosurfactant was determined against 5 bacterial organisms namely . Often the activity of biosurfactant is mostly related to an inhibition of pathogen adhesion rather than a direct antimicrobial activity or inhibition of the cell growth anti-adhesive properties of biosurfactants have a significant role in preventing the adhesion of pathogenic bacteria [ 34 ] in addition to the rate of bacterial deposition as . Importance of biosurfactant in food industry a wide range of biosurfactants has shown antimicrobial activity against bacteria, yeast, fungi, algae,.

Antimicrobial activity of biosurfactant extracts the antimicrobial activity of the identified surfactin and rhamnolipid extracts, produced by st34 and st5, respectively, were analysed against various actively growing reference (atcc), environmental and clinical gram-positive and gram-negative bacterial strains (table 1 ) as well as fungal . The antimicrobial activity of the biosurfactant was tested against several gram-positive and gram-negative bacteria using the agar spot assay method described by paik and et al each strain, used as an indicator, had been previously subcultured in its appropriate medium and temperature.
Biosurfactant-producing strains were evaluated for antibacterial activity against potentially pathogenic and food spoilage bacteria using the spot-on-lawn assay, of which 56% exhibited activity against only gram-positive bacteria, predominantly b cereus atcc 10702. Isolation and antimicrobial activity of rhamnolipid (biosurfactant) from oil contaminated soil sample using humic-acid salts-vitamin agar. Diethanolamide biosurfactant from c lanatus oil showed better antimicrobial activity than that of the sulphated diethanolamide from the same c lanatus oil table 3 antimicrobial activity of the oil and biosurfactants of c lanatus.
