Abstract
Triton X-100, as one of the most popular surfactants used in bioremediation techniques, has been reported as an effective agent enhancing the biodegradation of hydrocarbons. However efficient, the surfactant's role in different processes that together enable the satisfying biodegradation should be thoroughly analysed and verified. In this research, we present the interactions of Triton X-100 with the bacterial surfaces (hydrophobicity and zeta potential), its influence on the enzymatic properties (considering mono- and dioxygenases) and profiles of fatty acids, which then all together were compared with the biodegradation rates. The addition of various concentrations of Triton X-100 to diesel oil system revealed different cell surface hydrophobicity (CSH) of the tested strains. The results demonstrated that for Pseudomonas stutzeri strain 9, higher diesel oil biodegradation was correlated with hydrophilic properties of the tested strain and lower Triton X-100 biodegradation. Furthermore, an increase of the branched fatty acids was observed for this strain.

Abstract
Alkyl polyglucosides, due to their low toxicity and environmental compatibility, could be used in biodegradation of hydrophobic compounds. In this study, the influence of Lutensol GD 70 on the cell hydrophobicity and zeta potential was measured. The particle size distribution and surfactant biodegradation were also investigated. Microbacterium sp. strain E19, Pseudomonas stutzeri strain 9, and the same strain cultivated in stress conditions were used in studies. Adding surfactant to the diesel oil system resulted in an increase of the cell surface hydrophobicity and the formation of cell aggregates (a high polydispersity index). The correlation between cell hydrophobicity and zeta potential in examined samples was not found. The results showed a significant influence of Lutensol GD 70 on the changes in cell surface properties. Moreover, a high biodegradation of a surfactant (over 50 %) by tested strains was observed. The biodegradation of Lutensol GD 70 depends on the length of both polar and nonpolar chains. A long-term contact with diesel oil of stressed strain modifies not only cell surface properties but also its ability to a surfactant biodegradation.

Abstract
Diesel oil biodegradation by different bacteria-yeast-rhamnolipids consortia was tested. Chromatographic analysis of post-biodegradation residue was completed with chemometric tools (ANOVA, and a novel ranking procedure based on the sum of ranking differences). These tools were used in the selection of the most effective systems. The best results of aliphatic fractions of diesel oil biodegradation were observed for a yeast consortia with Aeromonas hydrophila KR4. For these systems the positive effect of rhamnolipids on hydrocarbon biodegradation was observed. However, rhamnolipids addition did not always have a positive influence on the biodegradation process (e.g. in case of yeast consortia with Stenotrophomonas maltophila KR7). Moreover, particular differences in the degradation pattern were observed for lower and higher alkanes than in the case with C22. Normally, the best conditions for "lower" alkanes are Aeromonas hydrophila KR4 + emulsifier independently from yeasts and e.g. Pseudomonas stutzeri KR7 for C24 alkane.

Abstract
AbstractThe immobilization of Amano Lipase A from Aspergillus niger by adsorption onto Stöber silica matrix obtained by sol-gel method was studied. The effectiveness of the enzyme immobilization and thus the usefulness of the method was demonstrated by a number of physicochemical analysis techniques including Fourier Transform Infrared Spectroscopy (FT-IR), elemental analysis (EA), thermogravimetric analysis (TG), porous structure of the support and the products after immobilization from the enzyme solution with various concentration at different times. The analysis of the process’ kinetics allowed the determination of the sorption parameters of the support and optimization of the process. The optimum initial concentration of the enzyme solution was found to be 5 mg mL-1, while the optimum time of the immobilization was 120 minutes. These values of the variable parameters of the process were obtained by as ensuring the immobilization of the largest possible amount of the biocatalyst at

Abstract
The Microbacterium sp. E19 (E19) has been isolated from soil contaminated with crude oil and is a candidate for surfactant enhanced remediation of hydrocarbon polluted soil. Oxyethylated alcohols (OA) are candidates for this process enhancement. The aim of this work was the investigation of biodegradation of a representative oxyethylated fatty alcohol (polydispersal surfactant C12E10(C12E10)) by E19 under static model conditions with the surfactant as a sole source of organic carbon. LC-MS was used for the identification of metabolites and determination of surfactant and metabolite concentrations. Apart from [M+NH4](+) ethoxylate 'fingerprints', [M+2NH4](++) 'fingerprints' (m/z=22) were used for the identification of particular species. Primary biodegradation of C12E10 by E19 is almost complete over 30 days of the test (97 percent). The major metabolites during the initial period of the test are homologs of oxyethylated alcohols ω-carboxylated in the oxyethylene chain and poly(ethylene glycols). 1/3 of the total C12Ex is metabolized along this pathway. Concentration of these metabolites is stable over the subsequent days of the test. Further biodegradation of C12Ex causes an enrichment of the residue with C12Ex homologs having a longer oxyethylene chain. However, intermediates of this process were not identified.

Abstract
Pseudomonas stutzeri strain 9 was isolated from petroleum-contaminated soil. The main purpose of this study was to investigate how the long-term contact of this strain with diesel oil influences its surface and biodegradation properties. The experiments showed that the tested strain was able to degrade aromatic alkyl derivatives (butylbenzene, sec-butylbenzene, tert-butylbenzene and isobutylbenzene) and that the storage conditions had an influence on the cell surface properties. Also greater agglomeration of the cells was observed in the scanning electron microscope (SEM) micrographs and confirmed in particle size distribution results. The results also indicated that the addition of rhamnolipids to the hydrocarbons led to modification of the surface properties of P. stutzeri strain 9, which could be observed in the zeta potential and hydrophobicity values.

Abstract
Twelve different bacteria-yeast combinations were tested for determination of their ability to biodegrade diesel oil. The cell surface properties of the bacterial and yeast strains were correlated with the type of carbon source used in the experiments. The highest biodegradation of diesel oil after 7 days was obtained for the following combinations: Aeromonas hydrophila MR4-Yarrowia lipolytica EH 56 (87 %) and Xantomonas maltophila MRP7-Candida maltosa EH15 (90 %). Degradation performances of 10 of 12 combinations were enhanced by the presence of rhamnolipids. The highest increases were observed for A. hydrophila MR4-C. maltosa EH15 (from 34 to 67 %), A. hydrophila MR4-C. maltosa EH60 (from 47 to 76 %) and for Pseudomonas stutzeri MR7-C. maltosa EH60 (from 29 to 79 %). The addition of rhamnolipids to the system reduces the removal time of diesel oil from the contaminated water and changes the microbial adhesion to hydrocarbons. Modification of the cell surface of the tested strain during biodegradation is a very important factor determining the removal of hydrophobic compounds.

Abstract
Three Pseudomonas aeruginosa strains isolated from petroleum-polluted soil were the subject of studies concerning changes in cell surface properties. Fundamentally different reactions could be observed for each of the studied strains after a cultivation on various carbon sources. The experiments carried out during the logarithmic growth phase showed, that the changes in the cell surface hydrophobocity values were dynamic and substrate dependant. An external addition of rhamnolipids to the tested systems resulted in further shifts in the CSH values. All of the strains displayed miscellaneous phenotypic properties during MATH, sedimentation profile, Zeta potential and surface tension measurements. The obtained results lead to a conclusion, that the presence of rhamnolipids seems to be the key factor to this phenomenon, as all of the studied strains exhibited the ability to produce this biosurfactant in a different degree.

Abstract
The objective of this research was the evaluation of the effects of exogenous added surfactants on hydrocarbon biodegradation and on cell surface properties. Crude oil hydrocarbons are often difficult to remove from the environment because of their insolubility in water. The addition of surfactants enhances the removal of hydrocarbons by raising the solubility of these compounds. These surfactants cause them to become more vulnerable to degradation, thereby facilitating transportation across the cell membrane. The obtained results showed that the microorganism consortia of bacteria are useful biological agents within environmental bioremediation. The most effective amongst all, as regards biodegradation, were the consortia of Pseudomonas spp. and Bacillus spp. strains. The results indicated that the natural surfactants (rhamnolipides and saponins) are more effective surfactants in hydrocarbon biodegradation as compared to Triton X-100. The addition of natural surfactants enhanced the removal of hydrocarbon and diesel oil from the environment. Very promising was the use of saponins as a surfactant in hydrocarbon biodegradation. This surfactant significantly increases the organic compound biodegradation. In the case of those surfactants that could be easily adsorbed on cells of strains (e.g., rhamnolipides), a change of hydrophobicity to ca. 30-40% was noted. As the final result, an increase in hydrocarbon biodegradation was observed.

Abstract
Biodegradation of water insoluble hydrocarbons can be significantly increased by the addition of natural surfactants one. Very promising option is the use of saponins. The obtained results indicated that in this system, after 21 days, 92% biodegradation of diesel oil could be achieved using Pseudomonas alcaligenes. No positive effect on the biodegradation process was observed using synthetic surfactant Triton X-100. The kind of carbon source influences the cell surface properties of microorganisms. Modification of the surface cell could be observed by control of the sedimentation profile. This analytical method is a new approach in microbiological analysis.

Abstract
This study concerns the relation between hydrocarbon biodegradation in the presence of natural surfactants and cell hydrophobicity resulting from the use of these surfactants. The relative capabilities of two bacterial strains (Pseudomonas aeruginosa and Bacillus subtilis) and two yeast strains (Candida maltosa, Yarrowia lipolytica) were investigated. The selected microorganisms were tested separately and in combination in order to achieve the optimal degrading performance. The surface cell hydrophobicity of microorganisms and the degree of hydrocarbon biodegradation were measured. The microbial adhesion to the hydrocarbon (MATH) test was used to denote the surface cell hydrophobicity of the microbial species. The results indicate the correlation between the modification of the surface cell and the degree of hydrocarbon biodegradation; however results for bacteria differ from that obtained for yeast strains. Saponins, as the surfactant, was more effective than rhamnolipides during hydrocarbon biodegradation, though the concentration of this surfactant has no significant influence on the surface cell hydrophobicity.
