“…In our study, biosurfactant produced in SmF had the highest E 24 and E 48 values, despite reducing surface tension to levels lower than SSF (with and without shaking). In the study of Abouseoud et al (2008), biosurfactants produced by P. fluorescens with 3 different carbon sources (hexadecane, olive oil, and glucose) had much the same surface tension value, although E 24 values showed changes. According to these results, it can be deduced that surface tension and emulsification index are based on growth medium components and growth condition.…”

IntroductionSurfactants are amphiphilic surface-active agents possessing both hydrophilic and hydrophobic moieties, which reduce surface and interfacial tensions between 2 immiscible fluids such as oil and water (Saharan et al., 2011). Biosurfactants are structurally diverse groups of surfactants synthesized by microorganisms. The major classes of biosurfactants are glycolipids, lipopeptides, phospholipids, and polymeric and particulate surfactants (Nitschke and Costa, 2007). They mainly reduce surface tension, critical micelle concentration, and interfacial tension between liquid-liquid/liquid-solid systems (Marchant and Banat, 2012). Biosurfactants have numerous advantages compared to their chemically synthesized counterparts: they can be produced from renewable resources, they are active under extreme conditions (pH and temperature), they are highly biodegradable, and they have low toxicity (Nott et al., 2013). They are widely used in the pharmaceutical, biomedical, cosmetic, petroleum, and food industries, as well as in environmental and agricultural applications. Considering these properties, the importance of biosurfactant production by different biological sources can be understood. In recent years, Pseudomonas, Bacillus, and Candida species have been particularly known as the predominant biosurfactant producers (Nitschke and Costa, 2007). Microbial production of biosurfactants is growth-associated and may possibly occur with the growth of microbial cells under growth-restrictive conditions (Saharan et al., 2011). Physicochemical properties and production efficiency of biosurfactants might be changed depending on the chemical compounds of the growth medium and the microorganism. Biosurfactants, produced from bacteria and yeast species, have been widely studied and their physicochemical properties have been determined. Although biosurfactant producer fungi species have not been sufficiently studied, as far as we know, Aspergillus fungus species are known as biosurfactant producers (Colla et al., 2010).According to numerous studies, the culture conditions solid-state fermentation (SSF) and submerged fermentation (SmF) are the most effective parameters of biosurfactant production (Neto et al., 2008;Colla et al., 2010). SSF has some advantages, such as the use of lowcost substrates and simple equipment, low volumes of water, low energy demand, and higher concentration of

“…Biosurfactants have recently received much more attention due to their potential to become an environment-friendly alternative to conventional synthetic surfactants. Advantages of biosurfactants over their synthetic counterparts include lower toxicity, biodegradability, better environmental compatibility, higher foaming, high selectivity, and specific activity at extreme temperatures, pH and salinity (Desai and Banat, 1997;Makkar and Cameotra, 1999;Makkar and Cameotra, 2002;Ilori et al, 2005;Raza et al, 2007;Abouseoud et al, 2008;Fontes et al, 2012).…”

“…Biosurfactants are a leading group of valuable microbial natural products with unique biochemical properties. From a biotechnology prospective, the production of biosurfactants is important owing to their vast applications in food, cosmetics, pharmaceuticals, and the agricultural and petrochemical industries (Robert et al, 1989;Pruthi and Cameotra, 2003;Abouseoud et al, 2008;Nguyen et al, 2008). They are interesting amphiphilic biomacromolecules with various biological functions/ properties such as; enhancer of polycyclic aromatic hydrocarbon bioavailability to microorganisms and, accordingly, their biodegradation, reducer of the interfacial tension by partitioning preferentially at interfaces, effective activity on surfaces, oil recovery, and so on (Desai and Banat, 1997;Pruthi and Cameotra, 2003;Joshi et al, 2008;Nguyen et al, 2008).…”

-Pseudomonas aeruginosa TMN was used to produce rhamnolipid (RL) from a variety of carbon and nitrogen substrates. The most favorable carbon sources for RL production were glucose and glycerol (both at 40 g/L), giving a RL yield of 0.3 and 0.25 g/L, respectively. Meanwhile, sodium nitrate appeared to be the preferable nitrogen source, resulting in a RL production of 0.34g/L. Rhamnolipid production from P. aeruginosa TMN was affected by temperature, pH and agitation rate, with 37 °C, pH 7 and 200 rpm agitation favorable for rhamnolipid production. Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR) and electro spray ionization-mass spectrometry (ESI-MS) analyses indicated that the purified product contained one type of commonly found rhamnolipid, which is L-rhamnosyl-L-rhamnosyl-β-hydroxydecanoyl-β-hydroxydecanoate. The rhamnolipid product can reduce the surface tension of water to 34 mN/m with a critical micelle concentration of nearly 18.75 mg/L and emulsified kerosene by 46%. P. aeruginosa TMN strain is a potential source of rhamnolipid biosurfactant, which could be used for the development of bioremediation processes in the marine environment.

“…Furthermore, olive oil was found the best carbon source for the biosurfactant production. Pseudomonas fluorescens Migula 1895-DSMZ was reported to produce rhamnolipid biosurfactant with the highest yield when olive oil used as a carbon source [44]. Plant-derived oils have been documented as an excellent carbon substrates for biosurfactant production by Pseudomonas aeruginosa [45,46].…”
