Acidobacteria have been described as one of the most abundant and ubiquitous bacterial phyla in soil. However, factors contributing to this ecological success are not well elucidated mainly due to difficulties in bacterial isolation. Acidobacteria may be able to survive for long periods in soil due to protection provided by secreted extracellular polymeric substances that include exopolysaccharides (EPSs). Here we present the first study to characterize EPSs derived from two strains of Acidobacteria from subdivision 1 belonging to Granulicella sp. EPS are unique heteropolysaccharides containing mannose, glucose, galactose and xylose as major components, and are modified with carboxyl and methoxyl functional groups that we characterized by Fourier transform infrared (FTIR) spectroscopy. Both EPS compounds we identified can efficiently emulsify various oils (sunflower seed, diesel, and liquid paraffin) and hydrocarbons (toluene and hexane). Moreover, the emulsions are more thermostable over time than those of commercialized xanthan. Acidobacterial EPS can now be explored as a source of biopolymers that may be attractive and valuable for industrial applications due to their natural origin, sustainability, biodegradability and low toxicity.

“…In addition, the efficiency of a Jatropha oil derived sophorolipids biosurfactant produced by C. bombicola (ATCC22214) as a stain cleaner was reported by Joshi‐Navare et al., (2013) . Other studies reported that biosurfactants are used as detergents in cleaning up hydrocarbon/crude oil storage tank and in a dish‐washing product . Moreover, the efficiency of the wetting behavior of biologically produced rhamnolipids respectively on glass, PET, polyvinylchloride (PVC), poly ε ‐caprolactone (PCL) and a polymer blend PVC–PCL and on glass, PET and gold surface were evaluated.…”

“…The wetting power allows the detergent solution to penetrate the pores until contamination with the impurities, the emulsifying activity maintains the impurities in solution, the foaming action causes the soiling, the dispersing power prevents the aggregation of soiling and the solubilizing property dissolves organic liquids . However, biosurfactants have advantages over their chemical counterpart some of which are structural diversity and stability at relatively high temperature and in adverse environments with the possibility of being produced from cheap raw materials . They have also been found to possess several properties of therapeutic and biomedical importance: they have antibacterial, antifungal and antiviral properties and they have anti‐adhesive action against several pathogenic microorganisms etc .…”

“…They have also been found to possess several properties of therapeutic and biomedical importance: they have antibacterial, antifungal and antiviral properties and they have anti‐adhesive action against several pathogenic microorganisms etc . More importantly, biosurfactants have drawn the interest of different industries due to their higher biodegradability, low toxicity and biocompatibility . The fact that they can be readily biodegraded means that they are significantly less damaging to the environment than the more recalcitrant chemical surfactants .…”

Surfactants play a very important role in laundry and household cleaning products ingredients. In this research, the application of lipopeptide biosurfactants, produced by Bacillus subtilis SPB1, in the formulation of a washing powder was investigated. The SPB1 biosurfactant was mixed with sodium tripolyphosphate as a builder and sodium sulfate as filler. The efficiency of the formulated detergent composition with different washing conditions to remove a stain from cotton fabric was examined. The results showed that the formulated detergent was effective in oil removal, with optimal washing conditions of pH, temperature, striate and time of washing system of 7, 65°C, 1000 RPM and 60 min, respectively. A comparative study of different detergent compositions (biosurfactant-based detergent, combined biosurfactantcommercial detergent, and a commercial detergent) for the removal of oil and tea stains, proved that the bio-scouring was more effective (>75%) in terms of the stain removal than the commercial powders (<60%). Moreover, the results demonstrated that the biosurfactant acts additively with a commercial detergent and enhances their performance from 33 to 45% in removing oil stain and from 57 to 64% in removing tea stain. As a conclusion, in addition to the low toxicity and the high biodegradability of the microbial biosurfactants, the results of this study have shown that the future use of this lipopeptide biosurfactant as laundry detergent additive is highly promising.

The biosurfactants are used by several industrial sectors such as petroleum, agriculture, food production, chemistry, cosmetics, and pharmaceuticals. Because of their hydrophobic and hydrophilic moieties, they have potency to reduce surface tension, interfacial tension between water-hydrocarbon systems, and low micelle concentration. Their characteristics strongly depend on the producer strain as well as on the medium composition, such as carbon and nitrogen sources. This study was conducted to investigate the influence of different sources of carbon (n-hexadecane, glycerol and glucose) and nitrogen (urea, NH Cl and NaNO ) for the production of biosurfactants by a new strain of 4 3Pseudomonas aeruginosa B031 isolated from a rhizosphere of Paraserianthes falcataria L. Nielsen, a hardwood plant species at a phytoremediation field. The biosurfactant characteristics of the strain were evaluated, particularly its surface-active properties and potential to remove hydrocarbon. Glycerol was found to be the optimum carbon source, with rhamnose concentration, emulsification index, and critical micelle concentration (CMC) of 718 mg/L, 37%, and 35 mN/m, respectively. Sodium nitrate (NaNO ) was observed as the optimum nitrogen source, with rhamnose 3 concentration, emulsification index, and CMC of 290 mg/L, 30%, and 24 mN/m, respectively. These biosurfactants efficiently reduced surface tension of culture broth from 42 mN/m to 31 mN/m for the glycerol treatment and from 37 mN/m to 24 mN/m for the sodium nitrate treatment. The crude biosurfactants from the glycerol and sodium nitrate treatments also removed 87.5% and 84%, respectively, of crude oil from sand. These rates were higher than those of the chemical surfactants (SDS and Triton X-100). These findings indicate that the biosurfactants produced by the strain from both glycerol and NaNO treatments can efficiently decrease the interfacial tension of culture broth 3 dilution and have a high emulsion index, thus hold promise in hydrocarbon bioremediation application.
