“…In comparison to chemical surfactants, biosurfactants possess lower toxicity, higher biodegradability and environmental compatibility, and can be produced from regenerated biomass resources and industrial by-products [7]. Therefore, in addition to classical cleaning applications, they have promising applications in environmental protection, crude-oil recovery, food-processing, biofilm prevention and disruption, and in various fields of biomedicine [8–10]. Glycolipids are a group of the most common biosurfactants and mainly consist of sophorolipids, mannosylerythritol lipid, cellobiose lipids, liamocins and polyol esters of fatty acids [4].…”

Background Polyol esters of fatty acids (PEFA) are a kind of promising biosurfactants and mainly secreted by Rhodotorula strains. In addition, some strains of Rhodotorula are reliable producers of microbial lipid. Therefore, it is feasible to establish a one step fermentation process for efficient simultaneous production of PEFA and microbial lipids by a suitable Rhodotorula strain. Results A newly isolated deep-sea yeast, Rhodotorula paludigena P4R5, was shown to simultaneously produce high level of intracellular lipid and extracellular PEFA. Under the optimized conditions, it could yield 48.5 g/L of PEFA and 16.9 g/L of intracellular lipid within 156 h from inulin during 10-L batch fermentation. The PEFA consisting of a mixture of mannitol esters of 3-hydroxy C 14 , C 16 and C 18 fatty acids with variable acetylation showed outstanding surface activity and emulsifying activity, while the fatty acids of the intracellular lipid were mainly C 16 and C 18 and could be high-quality feedstock for biodiesel production. Conclusion The deep-sea yeast strain R. paludigena P4R5 was an excellent candidate for efficient simultaneous of biosurfactants and biodiesel from inulin. Our results also suggested that the establishment of fermentation systems with multiple metabolites production was an effective approach to improve the profitability.

“…For example, diesel oil constitutes a complex mixture of hundreds of aromatic hydrocarbons, predominantly iso-alkanes, paraffinic, olefinic, naphtha and aromatic compounds (Yakimov et al, 2005) while used engine oil contains a variety of recalcitrant compounds, like alkyl benzenes, naphthalenes, methylnaphthalenes, PAHs and metals (Dominguez-Rosado and Pitchell, 2003;Lu and Kaplan, 2008). Marchut-Mikolajczyk et al (2018) reported that B. pumilus 2A was an effective hydrocarbon degrader of both diesel oil and waste engine oil but exhibited different degree of diesel oil and engine oil degradation. In addition, 2A strain showed different degradation efficiency of each hydrophobic component found in the two petrochemical products.…”

Hydrocarbons released into ecosystems have led to environmental pollution and generated a serious threat to human health. Bioremediation is an effective method to break down hazardous hydrophobic environmental contaminants with avoiding economic and technical disadvantages. This study aimed to evaluate the efficiency of Bacillus subtilis SE1, a lipopeptide biosurfactant producer isolated from a petrochemical contaminated soil, on biodegradation of gasoline, diesel oil, crude oil and used engine oil in soil microcosms. During 35-day incubation, numbers of soil bacteria in petrochemical contaminated soils with B. subtilis SE1 addition significantly (P < 0.05) increased in comparison with the oil-free soils. Bioaugmentation of SE1 strain also produced a significant (P < 0.05) increase in percent reduction of total phenolic content in oil-polluted soils as compared to the control soils at the end of experiment. This study indicates that B. subtilis SE1 can be a promising hydrocarbon degrader for in situ bioremediation of soil environment polluted with petroleum and petrochemical products.

“…Recalcitrant hydrocarbon (present in engine oil) degrading microbes of genus Bacillus produce biosurfactants of a diverse chemical nature and molecular size, with different active role(s). These microbial biosurfactants have the capability to degrade hydrocarbons enhancing the bioavailability of hydrophobic organic compounds in engine oil [ 8 ]. In recent era, biosurfactants have received special attention due to their unique properties like biodegradability, eco-friendly and low toxicity [ 9 ].…”

Engine oil used in automobiles is a threat to soil and water due to the recalcitrant properties of its hydrocarbons. It pollutes surrounding environment which affects both flora and fauna. Microbes can degrade hydrocarbons containing engine oil and utilize it as a substrate for their growth. Our results demonstrated that cell-free broth of Bacillus velezensis KLP2016 (Gram + ve, endospore forming; Accession number KY214239) recorded an emulsification index (E24%) from 52.3% to 65.7% against different organic solvents, such as benzene, pentane, cyclohexane, xylene, n-hexane, toluene and engine oil. The surface tension of the cell-free broth of B. velezensis grown in Luria–Bertani broth at 35 °C decreased from 55 to 40 mN m−1at critical micelle concentration 17.2 µg/mL. The active biosurfactant molecule of cell-free broth of Bacillus velezensis KLP2016 was purified by Dietheylaminoethyl-cellulose and size exclusion chromatography, followed by HPLC (RT = 1.130), UV–vis spectrophotometry (210 nm) and thin layer chromatography (Rf = 0.90). The molecular weight of purified biosurfactant was found to be ~ 1.0 kDa, based on Electron Spray Ionization-MS. A concentration of 1980 × 10–2 parts per million of CO2 was trapped in a KOH solution after 15 days of incubation in Luria–Bertani broth containing 1% engine oil. Our results suggest that bacterium Bacillus velezensis KLP2016 may promise a new dimension to solving the engine oil pollution problem in near future.
