“…New prospects for industrial production are focused on biotechnological processes that use agro-industrial wastes as substrates in formulating alternative medium in fermentation processes for producing secondary metabolites with a view to decreasing the costs of production (Accorsini et al, 2012;Antunes et al, 2013;Yasmin et al, 2016). In addition, this market shows promise to attract interest in the studies of biosurfactants that can be used as raw material in applications in the food-, agrochemical, cosmetics and pharmaceuticalindustries (Morikawa et al, 2000;Luna et al, 2009;Santos et al, 2016).…”

The world market for biosurfactants has grown gradually. However, the lack of competitiveness with chemical surfactants due to high cost of production remains a concern. Considering the need to reduce the costs of production, the aim of this work was to study the production and structural characterization of a biosurfactant produced by a strain of yeast Candida glabrata UCP 1556. The lowcost medium containing agro-industrial wastes whey 40% (v/v) and 20% (v/v) corn steep liquor were used as substrates in submerged fermentation. Biosurfactant production was detected by surface tension, oil displacement test and Critical Micelle Concentration (CMC). The structural characterization was performed by Fourier transform infrared (FT-IR), gas chromatography-mass spectrometry (GC-MS) and ionic profile. The stability of emulsions and potential in reducing the viscosity also were investigated. The results showed that the biosurfactant reduced the surface tension to 28.8 mN/m with CMC of 2% and showed anionic profile. Additionally, the biosurfactant formed stable emulsions at temperature (0 to 120°C), pH (2 to 12) and NaCl (2 to 12%), reduced the viscosity of soybean oil (

“…For instance, C. tropicalis can produce biosurfactants such as Lipomannan and Sophorolipid, so as the P. aeruginosa that produced glycolipid type biosurfactants named Rhamnolipids [19]. According to Antunes et al [20], C. violaceum also a potential biosurfactantproducing bacteria. These biosurfactants was all proven to emulsify oil and reduce surface tension in low concentration [11].…”

“…This enhanced the solubility of hydrophobic compound and also the dispersion of hydrocarbons, thus facilitate the uptake of crude oil by microbes [19]. Biosurfactants also altered the cell membrane by increasing its hydrophobicity to enhance direct physical contact between the cell and crude oil [20]. In short, biosurfactants improved affinity of microbes to the substrates, thereby enhanced biodegradation efficiency.…”

A biodegradation study was performed to assess the biodegradation of crude oil in seawater by consortium of Candida tropicalis RETL-Cr1, Pseudomonas aeruginosa BAS-Cr1 and Chromobacterium violaceum MAB-Cr1. Two independent experiments using different growth substrates, 5 mM glucose and 5% (v/v) crude oil, were undertaken to compare the microbial growth profile. The study was carried out using shake flask culture at 30°C, agitated 200 rpm. Microbial growth profile was monitored by measuring the optical density (OD600) on hourly and weekly basis. Biodegradation efficiency and rate were quantified by comparing the initial and final crude oil concentration, whereas the degradation of selected aliphatic hydrocarbons was quantified by comparing the initial and final area in chromatogram. The biodegradation ratios were monitored using Gas Chromatography Mass Spectrometry (GC-MS) method. Present finding showed that glucose was completely utilized at T10. However, the consortia can growth in crude oil even after 28 days. Overall biodegradation efficiency is 69.74% while the overall biodegradation rate is 24.85 g/L/d. The consortia could degrade 37% of n-alkane in crude oil after 28 days. Besides, biodegradation ratios shown that biodegradation had took place throughout the degradation period. It can be concluded that the consortia have high potential to degrade crude oil efficiently.

“…The main properties of potent biosurfactants are emulsifying and solubilizing capacity, reduction of surface tension and interfacial activity. These properties are already widely applied in industrial area as wetting, solubilizing and foaming substances, among others (Antunes et al, 2013).…”

In this work it was investigated the potential of Mucorales fungi isolated from the Caatinga of Pernambuco state for production of biosurfactants using renewable substrates. The strains (Mucor circinelloides UCP 0005, M. circinelloides UCP 0006 and Rhizopus arrhizus UCP 1609) were cultivated in alternative culture media consisting of instant noodle waste (INW), corn steep liquor (CSL) and post-frying soybean oil (PFSO), according to conditions established by a 23 full-factorial design (FFD). The production of biosurfactants was evaluated by determining surface tension and emulsification index (EI24) and statistical analysis was performed using Pareto diagram. The presence of the main sources of carbon and nitrogen in production medium was confirmed by FTIR spectroscopy. According to the results, the three fungi evaluated were able of produce biosurfactant in media containing renewable sources. However, the strain that showed the greatest reduction in surface tension (72 to 27 mN/m) was M. circinelloides UCP 0006 in condition 3 of the FFD (1% INW and 4% CSL, in absence of PFSO). The infrared analysis of the INW showed the presence of carbohydrates, fatty acids and proteins, proving that this is a suitable substrate for the cultivation of fungi. The biosurfactants produced by M. circinelloides UCP 0005 and M. circinelloides UCP 0006 were able to form water-in-oil emulsions and the biosurfactant from R. arrhizus UCP 1609 formed oil-in-water emulsions. The present study demonstrated that the three Mucorales fungi tested were able to produce biosurfactants from renewable sources, with emphasis on M. circinelloides UCP 0006.
