“…For example, surface modifications with UV/O 3 [1] or with plasmas such as corona discharges [2] can increase proliferation and protein expression of cells or enhance their culture process. Similar action can be obtained with coatings with well-defined surface chemistries as they can also amplify, or prevent, bioadhesion of molecules, cells and, in some cases, bacteria [7][8][9][10].…”

“…Additionally, EPS content can vary significantly, resulting in cell hydrophobicity changes, namely in a ratio between lipophilic and hydrophilic areas on the cell surface [92,[105][106][107][108][109][110]. As a rule, hydrophobic interactions dominate electrostatic ones in the bacterial adhesion process [106], although the number of adhered rhodococcal cells is not necessary in a linear dependence on hydrophobicity or zeta-potential values [111]. [112] and reference [45], respectively.…”

The review is devoted to biocatalysts based on actinobacteria of the genus Rhodococcus, which are promising for environmental biotechnologies. In the review, biotechnological advantages of Rhodococcus bacteria are evaluated, approaches used to develop robust and efficient biocatalysts are discussed, and their relevant applications are given. We focus on Rhodococcus cell immobilization in detail (methods of immobilization, criteria for strains and carriers, and optimization of process parameters) as the most efficient approach for stabilizing biocatalysts. It is shown that advanced Rhodococcus biocatalysts with improved working characteristics, enhanced stress tolerance, high catalytic activities, human and environment friendly, and commercially viable are developed, which are suitable for wastewater treatment, bioremediation, and biofuel production.

“…Bacterial contamination by endogenous and/or exogenous sources, which may cause nosocomial infections and failure of the implants, is one of the biggest drawbacks for the implanted biomaterials. Therefore, it threatens patient's comfort, prolongs hospitalization or healing time, leading to morbidity, results in reoperations to remove the implant and leads to excessive cost . Bacterial adhesion is mediated by physicochemical interactions between bacterial strain and polymer surface and it depends on bacterial strain type, chemical composition of the polymer, surface chemistry, roughness, wettability, surface charge, and density .…”

“…Therefore, it threatens patient's comfort, prolongs hospitalization or healing time, leading to morbidity, results in reoperations to remove the implant and leads to excessive cost . Bacterial adhesion is mediated by physicochemical interactions between bacterial strain and polymer surface and it depends on bacterial strain type, chemical composition of the polymer, surface chemistry, roughness, wettability, surface charge, and density . Such surfaces are open for bacterial interaction, followed by its adhesion and colonization onto the biomaterial surface and finally leads to bacterial biofilm formation .…”

Bacterial contamination is one of the biggest drawbacks of implanted biomaterials, which may cause nosocomial infection. Avoiding bacterial adhesion onto the biomaterial surface by preparing active antibacterial biomaterials is an accurate solution. In this study, three of the fluoroquinolones: sparfloxacin, enrofloxacin, and lomefloxacin were selected due to their broad bactericidal effect and immobilized onto low-density polyethylene surface at two different pH values (pH 3 and pH 6), after tailoring the surface by plasma treatment followed by grafting of polymer brush of N-allylmethylamine. Surface wettability test and morphological investigations were carried out by water contact angle measurement and scanning electron microscopy analysis, respectively. Chemical characterizations were carried out by Fourier transform infrared spectra and X-ray photoelectron spectroscopy. Antibacterial activity was checked against Staphylococcus aureus and Escherichia coli strains and results revealed that prepared surfaces were more effective against E. coli than S. aureus especially those prepared at pH 6.
