1. Lipopeptide production by Bacillus subtilis R1 and its possible applications
Abstract The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different temperatures and salt concentrations, where it produced

2. Measured Dielectric Permittivity of Contaminated Sandy Soil at Microwave Frequency
Abstract Measurement of dielectric permittivity of soil has been studied by many researchers. However, few studies have been conducted on contaminated soil. The motivation of the present study is to investigate the behavior of sandy soil contaminated by lubricant oil at microwave frequency. Two different artificially prepared soil samples are measured in the

3. InfluÃncia do Ãleo de algodÃo, glicose e extrato de levedura Na produÃÃo de biossurfactante por uma nova linhagem de Candida glabrata
The production of surfactants of microbiologic origin has been intensively investigated during the last few years due their biotechnological potential and applications in different industrial sectors. Thus, the aim of the present work was to produce surfactants by a new strain of Candida glabrata UCP 1002 isolalated from mangrove sediments. Cotton seed oil,

4. Biotechnological production of surfactante of Bacillus subtilis in agro-industrial residue, characterization and applications. / Produção biotecnologica de surfatante de Bacillus subtilis em residuo agroindustrial, caracterização e aplicações.
Biosurfactants are amphypatic compounds from biologycal source showing both hydrophilic and lipophilic groups. Due to this feature, the biosurfactants acts decreasing the surface and interfacial tension of a liquid. The byproducts of agricola and industrial processing are an underexplored new sources to the production of biotechnological interesting compound

5. EVALUATION OF THE PERFORMANCE OF THE METHOD OF TPH DETERMINATION (TOTAL HYDROCARBON PETROLEUM) IN SAND FOR DETECTION IN INFRA RED / AVALIAÇÃO DO DESEMPENHO DO MÉTODO DE DETERMINAÇÃO DE TPH (TOTAL PETROLEUM HYDROCARBON) EM AREIA POR DETECÇÃO NO INFRAVERMELHO
This dissertation deals with an optimization of TPH (Total Petroleum Hydrocarbon) analysis methodology for samples of contaminated sands, validating the infrared detection technique through the use of Infracal TOG/TPH equipment. Tests were validated using Marine Fuel 380 oil, density 0.987 g cm-3 and viscosity 5313 cP at 20 0C. This oil sample was kindly sup

6. Bioremediation Potential of Terrestrial Fuel Spills †
A bioremediation treatment that consisted of liming, fertilization, and tilling was evaluated on the laboratory scale for its effectiveness in cleaning up a sand, a loam, and a clay loam contaminated at 50 to 135 mg g of soil−1 by gasoline, jet fuel, heating oil, diesel oil, or bunker C. Experimental variables included incubation temperatures of 17, 27, an

7. Field evaluations of marine oil spill bioremediation.
Bioremediation is defined as the act of adding or improving the availability of materials (e.g., nutrients, microorganisms, or oxygen) to contaminated environments to cause an acceleration of natural biodegradative processes. The results of field experiments and trials following actual spill incidents have been reviewed to evaluate the feasibility of this ap
