“…Similar results have been reported by Zhu et al (2017), who also investigated the BPA removal capability of LAB. In addition, similar results have also been observed in removal assays on other carcinogens, such as cypermethrin (Zhang et al 2021) and zearalenone (El-Nezami et al, 2004). In this research, nonviable cells retained their BPA removal capability, and their removal level was even higher than the removal level of viable cells, indicating that adsorption, rather than degradation or transformation, is the mechanism through which BPA is removed from the solution.…”

Aims:The current study aimed to evaluate the capacity of two Lactiplantibacillus plantarum strains to remove Bisphenol A (BPA) and to determine the preliminary removal mechanisms underlying this process. Methods and Results:The BPA removal capacity of L. plantarum RS20D and DL7X was assessed by HPLC analysis. The effect of various treatments (physical, chemical and enzymatic) on two strains were studied to understand which interaction types worked. The different cellular components of them were also subjected to binding assays. Additionally, Fourier-transform infrared spectroscopy (FTIR) was performed to identify the functional groups related to the BPA-binding process. Results show that various treatments enhanced the binding capacity of two strains, the effect of sodium dodecyl sulphate was the most outstanding (p < 0.05). Hydrogen bonding and hydrophobic interactions likely occurred. Peptidoglycans showed the highest binding capability, protoplasts and teichoic acids might also exert a binding effect.-OH, C=O, -CH, -NH, C-N, C-O and P=O participated in BPA binding by the two L. plantarum lines.Conclusions: Peptidoglycans, protoplasts and teichoic acid played a vital role in the binding of BPA.

“…2,4-dihydroxybutanoic acid and phenethylamine were reduced as well (Table 3), while α-hydroxybutyric acid was strongly increased. All of these metabolites are mainly involved in energy metabolism, as previously suggested by Zhang et al (2021) when evaluating metabolomic results from P. pentosaceus exposed to oxidative stress. Zhang et al (2021) suggested that the partial increase of amino acids most probably results from an active defense response of some bacteria.…”

Aims:The objective of this study was to isolate multifunctional bacteriocin-producing strains; to characterize the expressed bacteriocin for the control of Listeria monocytogenes and vancomycin-resistant Enterococcus; to evaluate the safety of studied strains; and to explore their antifungal activity. Methods and Results: Two Pediococcus strains were isolated from silage samples obtained from an organic farm in Belogradchik, Bulgaria. The strains were identified by 16S rRNA sequencing analysis and characterized as bacteriocins producers. Strong antimicrobial activity was detected against more than 74 different strains of Listeria monocytogenes, 27 different vancomycin-resistant Enterococcus strains. In addition, studied strains were able to inhibit the growth of strains of Alternaria alternate, Aspergillus flavus, Aspergillus niger, Cladosporium sphaerospermum, Penicillium chrysogenum and Penicillium expansum. Some aspects of the antimicrobial mode of action were evaluated, including killing curves and aggregation properties. Both strains generated positive PCR results for the presence of pediocin PA-1, but not for other bacteriocins evaluated in this screening process. Metabolomic analysis of the cell-free supernatants from both strains was performed in order to explain the observed antifungal activity against different moulds. According to PCA and PLS-DA score plot, P. acidilactici ST3522BG and P. pentosaceus ST3633BG were clearly clustered from control (MRS). Increases in the production of benzoic acid, 2-hydroxyisocaproic acid, β-phenyl-lactic acid, α-hydroxybutyric acid and 1,3-butanediol were recorded, these metabolites were previously described as antifungal. Conclusions: Pediococcus acidilactici ST3522BG and P. pentosaceus ST3633BG were evaluated as producing bacteriocin strains with high specificity against Listeria and vancomycin-resistant Enterococcus species. In addition, both investigated Pediococcus strains were evaluated as producer of effective antifungal metabolites with potential for the inhibition of mycotoxin-producing moulds. Significance and Impact of the Study:To the best of our knowledge, this report is a pioneer in the evaluation of Pediococcus strains isolated from silage with highly specific bacteriocinogenic antimicrobial activity against Listeria spp. and vancomycin-resistant Enterococcus spp., and antifungal activity against mycotoxin-producing moulds.
