“…The immobilization of brevicin onto food-grade SiO 2 (SigmaAldrich, MO, USA) adsorbent was performed as described by Dawson et al (2005). The effect of exposure time (0-360 min), temperature (10-60°C), pH (2-10), and initial activity (200-3,200 AU/ml), on the potential of silica to adsorb brevicin, was studied by OFAT method (Ibarguren et al 2010).…”

“…A brevicin solution containing 200 AU/ml 1 % (w/v) was mixed with silica powder, stored for 4 h at 40°C, and centrifuged (12,000×g, 10 min) and the supernatant tested for antimicrobial activity . The resultant particles were dried at 30°C for 16 to 18 h. The antibacterial activity of brevicin adsorbed on silica powder was measured by well diffusion assay carried out with L. monocytogenes (Dawson et al 2005). Fourier transform infrared (FTIR) (Perkin-Elmer, Waltham, Massachusetts, USA) spectra for the surface functional groups in the spectral range of 400-4, 000 cm −1 were obtained using KBr as reference.…”

Bacteriocins are nowadays recognized as good biopreservatives that are able to contain microbial contaminant development in several food products. In this study, the goat milk isolate Lactobacillus brevis NS01 brevicin activity on common foodborne pathogenic organisms and its characterization, stability, and statistical response surface methodology (RSM) optimization of media components for enhanced production were determined. Its adsorption onto common stabilizing agent silica and applicability in apple juice preservation were also determined. The L. brevis NS01 produced 3.2 kDa common foodborne pathogen inhibitory brevicin having more polar (68.6 %) than non-polar (30.8 %) amino acids. Optimization of growth conditions by RSM demonstrated that glucose, sodium acetate, and triammonium sulfate concentration of 33.41, 8.36, and 2.22 g/L, respectively, increased its production. Brevicin activity was constant over a broad range of pH (3-8) and temperature (20-100°C) and reached a maximum at pH 6 and 40°C. Maximum adsorption of brevicin onto silica took place at pH 6-7, 40°C for 240 min. The carrier silica exhibited significant Fourier transform infrared (FTIR) spectral changes upon brevicin adsorption and presented good biopreservative activity. This study demonstrates the potential large-scale use of brevicin adsorbed silica for shelf life increase and clarification at a same time.

“…Antibacterial Starch-Based Materials with Miscellaneous Components Apart from bioactive plant extracts and chitosan, several other components have been used to prepare antibacterial starchbased material, namely, lysozyme (Basch et al 2012;Dawson et al 2005;Li et al 2012b), nisin (Basch et al 2012;Dawson et al 2005), and the combination with other antibacterial cationic polymers as polyhexamethylene guanidine (Guan et al 2008a, b;Ziaee et al 2010), among others discussed below.…”

“…Nisin has been adsorbed into cornstarch powder (among other food-grade powders), by placing them in agitated nisin solutions, followed by dehydration and testing against L. plantarum or L. monocytogenes (Dawson et al 2005). Nisin adsorbed into starch preserved 54 % of its original activity, and between 45 % and 61 % of the peptide was released over time (depending on the initial load).…”

This chapter aims at presenting a comprehensive overview of the latest advances in the development of antibacterial materials based on chitosan, cellulose, and starch, which being the most abundant polysaccharides have a high potential to be explored in large variety of applications (e.g., food or biomedical fields).Owing to its intrinsic antibacterial and film-forming properties, chitosan can be directly used to create antibacterial materials. Thus, the first part of this chapter focuses mainly on the factors affecting its inherent bioactivity and the strategies potentially used to enhance it, in order to broaden chitosan-based materials applicability. Then the strategies developed to impart antibacterial properties to cellulose and starch, mainly through chemical modification or combination with bioactive natural and synthetic components and polymers as well as with metal and metal oxide nanoparticles, were screened in detail, pointing out their antibacterial profile and prospective applications.

Kieselguhr, bentonite, and montmorillonite were investigated as potential carriers of plantaricin Q7. Highest level of adsorption of plantaricin Q7 was obtained with montmorillonite. Meanwhile, visible inhibition zones were observed against Listeria monocytogenes for montmorillonite adsorbed with plantaricin Q7. Adsorption kinetics showed that the adsorption behaviour followed the pseudo‐first‐order and Weber's intra‐particle diffusion models, suggesting two steps had taken place during the adsorption process. X‐ray diffraction assays revealed that plantaricin Q7 was intercalated into the interlayer space of montmorillonites. Electrostatic, hydrogen bonding and hydrophobic interactions proved to play important roles in the mechanisms of interaction between montmorillonite and plantaricin Q7, as shown by infrared spectroscopy analysis. In addition, plantaricin Q7 production was inhibited by feedback regulation with its high concentrations. In order to remove product feedback inhibition in plantaricin Q7 production, a strategy was implemented for its adsorption onto montmorillonite during fermentation. The final plantaricin Q7 output reached 3713.40 IU/mL during fermentation using montmorillonite to adsorb plantaricin Q7, 41.61% higher than that of non‐ montmorillonite. These results indicate that montmorillonites are suitable carriers for plantaricin Q7 adsorption, and the adsorption of plantaricin Q7 onto montmorillonite during fermentation could be a good method to increase final plantaricin Q7 production.
