“…The possibility of bacterial adsorption onto the surface of nanostructures has been presented, e.g., in the work of Kang et al (2007) and Singh et al (2011). Similarly, the ability to create a biofilm and the adsorption of bacterial cells onto the surface of mineral materials, including carbon materials and modified clay minerals, were also demonstrated (Yee et al, 2000;Rivera-Utrilla et al, 2001;Yamamoto et al, 2001;Jiang et al, 2007;Rong et al, 2008). These studies also indicated the important roles of pH and the ionic strength of the solution as significant factors affecting the adsorption of bacterial cells onto the surface of minerals.…”

In this context, studies have shown the possibility of adsorbing Gram-positive and Gram-negative bacteria to minerals such as quartz, corundum, and iron-containing minerals.…”

A b s t r a c tThis paper presents the interactions of Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas putida) bacteria with ceramic materials obtained by combustion synthesis. These studies were conducted based on an analysis of the adsorption of bacteria onto aggregates of ceramic materials in an aqueous suspension. The materials used in the studies were of a nanostructured nature and consisted mainly of carbides: silicon carbide (SiC) in the form of nanofibers (NFs) and nanorods (NRs), titanium carbide, and graphite, which can also be formed by combustion synthesis. Micrometric SiC was used as a reference material. Gram-positive bacteria adsorbed more strongly to these materials. It seems that both the point of zero charge value and the texture of the ceramic material affected the bacterial adsorption process. Additionally, the viability of bacteria adsorbed onto aggregates of the materials decreased. Generally, P. putida cells were more sensitive to the nanomaterials than S. aureus cells. The maximum loss of viability was noted in the case of bacteria adsorbed onto NRSiC and NFSiC aggregates.

“…According to cation-exchange capacity, natural zeolites can adsorb or detoxify bacterial toxins and thus prevent the increased intestinal permeability and the damage produced by bacterial toxins (Andronikashvili et al 2009;Subramaniam & Kim 2015). Interaction between bacteria and the absorbents is controlled by electrostatic attraction (Rong et al 2008). Under physiologic conditions, bacterial cell walls are negatively charged while chabazite/ phillipsite structure presents mono and divalent exchangeable cations (i.e.…”

We evaluated whether chabazite/phillipsite dietary supplementation might affect the faecal microbiota, oxidant and antioxidant status of working dogs at rest undergone to a trial test. Forty English Setter dogs were involved in two replicate trials. At each replicate, dogs were divided into two homogeneous groups (10 dogs/group). During a period of 28 days, diet was supplemented (Z group) or not supplemented (C group) with chabazite/phillipsite at the dose of 5 g/head/day. On day 29, dogs were subjected to a trial test. Faecal characteristics were assessed at 0 and 29 days (within two hours from the end of the trial test). Faecal consistency was not affected by dietary supplementation (p > .05). On day 29, Lactobacillus spp. and Enterococcus spp. counts were higher and Enterobacteriaceae were lower in Z than in C group (p < .05). At day 0 and at day 29, immediately before and within one hour from the end of the trial test, blood samples were recorded to evaluate the oxidant and antioxidant status. A reduction of 40% in thiobarbituric acid reactive substances (TBARS) levels was observed in Z compared to the C group (p < .05). Differences in nitric oxide and antioxidant enzymatic system levels were not significant (p > .05). Our results suggest that chabazite/phillipsite dietary supplementation, improves the intestinal microbiota ecosystem and may counteract the oxidative damage caused by physical stress in hunting dogs at the beginning of the working season.ARTICLE HISTORY

“…Although the interactive forces are important in the adsorption process of bacteria on solids, other physical and biological factors can also influence this process, such as the size of bacterial cells, ionic strength and the surface structure of the supports [39][40][41]]. Thus, the major level of BDS activity observed in biocatalysts can be explained by high no-electrostatic interaction between the cells and supports [42]. So the access of P. aeruginosa cells to the hydrophobic phase is facilitated, in comparison to whole non-adsorbed cells [38].…”

Abstract:A new biodesulphurization method has been considered using Pseudomonas aeruginosa supported on polyethylene (PE) for biodesulphurization (BDS) of thiophene as an aromatic sulphur model compound of crude oils. Also the biodegradation of thiophene has been modified in the presence of potassium hexacyanoferrate(III) as a terminal electron acceptor to approach the maximum biodesulphurization efficiency. The obtaining results according to UV-Spectrophotometry at 240 nm, 83.3% of thiophene at the primary concentration of 50 mg/dm 3 , pH = 7, by 0.5 g of biocatalyst in 37°C after 4 h of contact time has been removed. The bacterial cells exhibited a greater and faster biodegradation in the presence of potassium hexacyanoferrate(III) and 94.8% of thiophene has been removed after 3 h of contact time. Kinetic study predicted chemisorption of thiophene on the surface of the biocatalyst, as it followed the pseudo-second-order rate equation. Morphology and surface functional groups of the biocatalyst have been investigated by SEM and FT-IR, respectively.
