“…After 24 h culture time, the surface tension was mostly constant at 30 mN/m. The result was agreed with P. aeruginosa MA01 [17] and Candida albicans [18]. Also, Rufino et al [19] reported that C. lipolytica UCP0988 produced rufisan biosurfactant during exponential growth phase.…”

Abstract-To enhance lipopetide biosurfactant production by Pseudomonas spp., the effects of medium and culture conditions were investigated. Nutrient broth (NB) supplemented with glucose and molasses as carbon sources were used to increase biosurfactant yield. Cultivation temperatures and initial pH were also studied. In this experiment, NB was used as a control to produce biosurfactant with the yield of 0.58 g/L. The lipopeptide biosurfactant yield was increased to 2.76 g/L when Pseudomonas spp. was cultured in NB supplemented with 1% w/v glucose, 500 µM FeSO4, pH 9.0 and cultivation of 20°C for 72 h. Its specific growth rate was 0.25 h-1.Index Terms-Pseudomonas spp., lipopeptide biosurfactant, glucose, ferrous.

“…NaCl activated biosurfactant activity of many strains isolated from several environmental sources including mangrove sediments (Saimmai et al, 2013). More recently, biosurfactant produced by P. aeruginosa MA01 has shown good stability of surface tension and emulsion in the presence of NaCl up to 300 g/L (Abbasi et al, 2012). Our findings indicate that the biosurfactant has potential application over a wide range of temperature, pH values and saline environment.…”

Pseudomonas aeruginosa strain KVD-HR42 exhibiting growth and biosurfactant production with 1% molasses as the sole carbon source was isolated from oil contaminated mangrove sediments. Optimization of media conditions involving variations in carbon, nitrogen sources, amino acids, pH, temperature, and NaCl% were evaluated with the aim of increasing biosurfactant productivity and surface tension reduction (STR). The highest biosurfactant production of 4.83 g/L was obtained when cells were grown in mineral salts media (MSM) supplemented with 1% (w/v) molasses, NaNO 3 , and leucine 0.1% (w/v) at 35±2°C at 150 rpm after 48 h. The results obtained from kinetics study indicated that biosurfactant production, E 24 %, and rhamnose concentration were growth associated. However, maximum biosurfactant production occurred in the exponential growth phase and detected an increase in E 24 % and rhamnose concentration. The Fourier transform infrared (FTIR) spectra confirmed the rhamnolipid nature of the biosurfactant. Stability studies revealed the thermostable activity of biosurfactant (110°C for 15 min) and could also withstand wide pH and NaCl ranges. Maximum oil biodegradation of 68% was achieved with 1% waste lubricant oil (WLO). The biosurfactant emulsified various hydrocarbons with varied efficiencies. However maximum E 24 % and E 48 % activity was exhibited with n-hexadecane (69.5 and 40%). The results reveal the potential of strain KVD-HR42 biosurfactant for the bioremediation of petroleum hydrocarbons in mangrove sediments.

“…A wide range of rhamnolipid production yield by Pseudomonas species using vegetable oils and/or their wastes as carbon source has been reported. P. aeruginosa produced rhamnolipid when grown on water-insoluble substrates such as coconut oil (2.26 g/L) (George and Jayachandran 2013), Mesua ferrea seed oil (6.95 g/L) (Singh et al 2013), soy bean oil (12 g/L) (Abbasi et al 2012), waste cooking oil (13.93 g/L) (Lan et al 2015), waste frying oil (6.6 g/L) (Luo et al 2013), and waste frying oil (24.61 g/L) (Zhu et al 2007). The rhamnolipid yield achieved in the present study with P. aeruginosa OG1 (13.31 g/L) using waste frying oil and CFP at optimal concentrations was much greater than the yields obtained in several previous studies.…”

In the present study, production of rhamnolipid biosurfactant by Pseudomonas aeruginosa OG1 was statistically optimized by response surface methodology. Box-Behnken design was applied to determine the optimal concentrations of 52, 9.2, and 4.5 g/L for carbon source (waste frying oil), nitrogen source (chicken feather peptone), and KH 2 PO 4 , respectively, in production medium. Under the optimized cultivation conditions, rhamnolipid production reached up to 13.31 g/L (with an emulsification activity of 80%), which is approximately twofold higher than the yield obtained from preliminary cultivations. Hence, rhamnolipid production, noteworthy in the literature, was achieved with the use of statistical optimization on inexpensive waste materials for the first time in the present study.
