Biosurfactants can be classified by their chemical composition and their origin. This review briefly describes various classes of biosurfactants based on their origin and introduces a few of the most widely used biosurfactants. The current status and future trends in biosurfactant production are discussed, with an emphasis on those derived from plants. Following a brief introduction of the prop...
Comparative Study for Biosurfactant Production by Using Bacillus subtilis and Pseudomonas aeruginosa
Biosurfactants are amphiphilic compounds produced by various bacteria and fungi which reduce surface and interfacial tension. Oil contaminated soil were collected from four different automobile shop in Mayiladuthurai, Tamilnadu, India. Bacillus subtilis and Pseudomonas aeruginosa were isolated and identified from these four samples and these were screened for biosurfactants production using veg...
The Yellow River Delta (YRD) is an important agricultural and ecological base that is being threatened by crude oil contamination. The remediation of the YRD can be potentially assisted by biosurfactants. Three native unknown biosurfactant-producing bacteria have been isolated (L1, L2, L3). In this paper, we measured the emulsification properties of the three biosurfactants in terms of emulsifi...
During the last years, several applications of biosurfactants with medical purposes have been reported. Biosurfactants are considered relevant molecules for applications in combating many diseases and as therapeutic agents due to their antibacterial, antifungal and antiviral activities. Furthermore, their role as anti-adhesive agents against several pathogens illustrate their utility as suitabl...
Increasing public awareness of environmental pollution influences the search and development of technologies that help in clean up of organic and inorganic contaminants such as hydrocarbons and metals. An alternative and eco-friendly method of remediation technology of environments contaminated with these pollutants is the use of biosurfactants and biosurfactant-producing microorganisms. The di...
background in recent decades, biological properties of biosurfactants, particularly glycolipids, including antimicrobial, antifungal, and anti-cellular effects have been projected in many research studies. the unique advantages of these compounds in terms of production and environment made them important as antimicrobial agents. objectives this study aims to evaluate probable antibacterial and ...
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...
Little is known about the interaction of biosurfactants with bacterial cells. Recent work in the area of biodegradation suggests that there are two mechanisms by which biosurfactants enhance the biodegradation of slightly soluble organic compounds. First, biosurfactants can solubilize hydrophobic compounds within micelle structures, effectively increasing the apparent aqueous solubility of the ...
Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several kinds of substrates, justifying its use for industrial production of those products. For this production to be economically viable, the use of residual carbon sources is rec...
Marine microorganisms possess unique metabolic and physiological features and are an important source of new biomolecules, such as biosurfactants. Some of these surface-active compounds synthesized by marine microorganisms exhibit antimicrobial, anti-adhesive and anti-biofilm activity against a broad spectrum of human pathogens (including multi-drug resistant pathogens), and could be used inste...
