“…The research of Han, Ji and Ni (2009) showed, that alkyl polyglucosides can have positive influence on the crude oil removal efficiency, thanks to their surface active properties. The similar findings presented Sałek, Zgoła-Grześkowiak and Kaczorek (2013), who also tested selected alkyl polyglucosides. Mohanty and Mukherji (2007) Comparing the obtained results of biodegradation efficiency and cell surface hydrophobicity using Statistica 10 software no significant correlation was noticed, in contrary to the observations of Kelkar, Kumar and Zinjarde (2007).…”

The use of surfactants in a bioremediation process is aimed at increasing the efficiency of the removal of hydrophobic contaminants from the environment. The subject of the study were three alkyl polyglucosides of different alkyl chain length: Glucopon 215 CS UP, Glucopon 600 CS UP and Glucopon 650 EC. The impact of these surfactants on the surface properties of the test strain Pseudomonas fluorescens ATCC 14700, as well as on the biodegradation of diesel was tested.It was observed, that the length of alkyl chain has an influence on the cell surface properties. The modification of the cell surface hydrophobicity and the electrokinetic potential on the bacteria cells is dependent on the structure of Glucopon molecules. The elongation of alkyl chains in surfactant molecule caused an increase of the hydrophobic properties and a reduction of the electrokinetic potential on the bacteria cells. Moreover, the use of alkyl polyglucosides below critical micelle concentration caused an increase of diesel oil biodegradation, especially in the case Glucopons with longer alkyl chain (Glucopon 600 CS UP and 650 EC). The better diesel oil removal by tested strain after surfactant addition was correlated with the hydrophobic properties of bacteria strain.

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.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-014-3668-z) contains supplementary material, which is available to authorized users.

“…[24][25][26] Furthermore, several works on microbial degradation of hydrocarbons demonstrated how some bacterial species of the Acinetobacter, Pseudomonas, Stenotrophomonas, and Enterobacter genera are unaffected by surfactants and, notably, they can even exploit soap as carbon source. [27][28][29] On the basis of the microbiological findings about the toys seized in Italy, the samples we processed, and the international notifications, we believe we have confirmed widespread microbial contamination. In addition to high TAMC and TYMC counts, biochemical testing identified 23 recurring species of bacteria.…”

In 2012 some children developed sepsis after playing together with a soap bubble toy. Microbiological testing revealed heavy contamination of the soap solution, which reasonably represented the vehicle of infection. We investigated the issue with a multidisciplinary approach: review of toy safety legislation; microbiological testing of additional samples; query of the RAPEX database for non-compliant soap bubbles; identification of major manufacturing districts. Microbiological contamination of industrial soap bubbles was widespread. Sixty-three notifications of batches contaminated by environmental microorganisms and opportunistic pathogens had been reported. The Chinese had a virtual monopoly of the soap bubble market. We identified two main manufacturing districts in Guangdong Province, both notable for degradation of their water resources. The use of untreated water for the industrial production of soap bubbles may explain the bacterial contamination. Existing legislation provides an unsatisfactory approach for managing microbiological hazards in sensitive toy categories and for identifying responsible parties in import and export of the products.
