Pseudomonas aeruginosa LBI (Industrial Biotechnology Laboratory) was isolated from hydrocarbon-contaminated soil as a potential producer of biosurfactant and evaluated for hydrocarbon biodegradation. The emulsifying power stability the product assessed in laboratory, simulating water contamination with benzene, toluene, kerosene, diesel oil crude at various concentrations.Bacteria were grown 30 degrees C shaken 200 rpm 168 h, three repetitions. Surface tension, pH observed cell-free broth...
The aim of this work was to investigate the potential diesel oil degrading yeasts use them in bioremediation areas contaminated by pollutant. cultures, identified as Rhodotorula aurantiaca UFPEDA 845 and Candida ernobii 862, were selected at initial stage. In course biodegradation assays, C. degraded tetradecane, 5 methyl-octane octadecane completely decane (60.8%) nonane (21.4%) partially whilst R. presented degradation percentages 93% for decane, 38.4% 22.9% dodecane.
Aedes aegypti mosquitoes are the primary transmitters of dengue fever, urban yellow fever and chikungunya viruses. This mosquito has developed resistance to insecticides currently used control their populations. These chemical harmful environment can have negative effects on human health. Rhamnolipids environmentally compatible biological surfactants, but insecticidal activity not been extensively studied. The present study evaluated potential larvicidal, repellent activities rhamnolipids...
Abstract The wetting behavior of rhamnolipids produced by Pseudomonas aeruginosa LBI strain grown on waste oil substrate and sodium dodecyl sulfate (SDS) glass, polyethylene terephthalate (PET), poly(vinyl chloride) (PVC), poly(ε‐caprolactone) (PCL) polymer blend (PVC–PCL) was investigated the measuring contact angle sessile drops, to determine characteristics rhamnolipids. comparison profiles showed that at low SDS rhamnolipid concentrations, increased when concentration surfactant further,...
Abstract This paper evaluates the effect of additives (NaCl and ethanol) on solution properties rhamnolipids. The are surface activity, aggregate formations emulsifying activity as well synergistic effects pH variations physical Additionally, analysis fatty acids rhamnolipid homologues produced using different carbon sources was performed by mass spectrometry. results indicate that this biosurfactant maintain its in presence additives. NaCl decreases size number aggregates formed solutions...
This study focused on two important aspects of the upstream process: appropriate use crude glycerol as a low-cost carbon source, and strain selection. The effect different concentrations rhamnolipid biosynthesis by Pseudomonas aeruginosa strains (wild type LBI mutant 2A1) was studied. Finally, synthesized rhamnolipids were characterized mass spectrometry. When both compared, 50 g/L most favorable concentration for both, but P. 2A1 showed an increase in production (2.55 g/L) 192% over wild...
Guava is consumed in natura and also of considerable importance to the food industry. The seeds peel this fruit are discarded, however, guava yield oil (~13%) that can be used for bioproducts synthesis. use a by-product as carbon source advantageous, it reduces environmental impact possible harmful materials nature, while adding value products. In addition, untested substrates bring new characterization results. Thus, research sought study rhamnolipids (RLs) production from seed oil,...
