Following are some of the major pathogenic bacteria found in wastewater and the diseases associated with them.16,17,20,21Salmonella typhi: causes typhoid fever, diarrhea.Salmonella paratyphi: causes paratyphoid fever, enteric infections.Salmonella typhiniurium: causes food poisoning, salmonellosis.Shigella sonnei: causes shigellosis (bacillary dysentery).Mycobacterium tuberculosis: causes tuberculosis.Enteropathogenic Escherichia coli: causes diarrhea or gastroenteritis.Vibrio cholerae: causes cholera, diarrhea, and dehydration.Yersina enterocolitica: causes diarrhea or gastroenteritis.Francisella tularensis: causes tularemia.Leptospira interrogans: causes leptospirosis, jaundice (Weil’s disease).

The antimicrobial activities of the nine LAB strains against 14 indicator microbial strains (Saccharomyces cerevisiae ATCC9080, Aspergillus niger CMCC(F)98003, Listeria monocytogenes ATCC19115, Escherichia coli CMCC(B)44102, Micrococcus luteus CMCC(B)28001, Enterobacter aerogenes ATCC13048, Serratia marcescens CMCC(B)41002, Vibrio parahaemolyticus ATCC17802, Shigella sonnei CMCC(B)51105, Pseudomonas aeruginosa CMCC(B)10104, Bacillus cereus CMCC(B)63303, Bacillus subtilis CMCC(B)63501, Salmonella paratyphi-B CMCC(B)50094, and Staphylococcus aureus CMCC(B)26003) procured from Shanghai Luwei Microbial Sci. & Tech. Co. Ltd., China. The indicator strains were grown on distinct nutrient agar and stored for further analysis. 200 μL of different indicator microorganisms in the stationary phase (107–109 CFU/mL) was inoculated into 15 mL of 1.2% (w/v) agar at 50 °C. The mixture was poured into a petri dish containing three Oxford cups 7.5 mm in diameter. After solidification, 200 μL of CFS from different LAB strains filtered through 0.22 μm membrane was added to two cups, while the third was used as the control (200 μL of sterile water). The antimicrobial inhibition zones were measured (in mm) after incubation at 37 °C for 48 hr. Each experiment was performed independently in triplicate.

Similarly, in a previous literatures, AgNPs synthesized by Bacillus megaterium showed high antibacterial activity against Salmonella typhi and Streptococcus pneumoniae as reported by Saravanan et al.[28] AgNPs synthesized by B. cereus showed antibacterial activity against Echerichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Salmonella typhi.[36] The data obtained about Bacillus flexus AgNPs confirmed their antibacterial activity against E. coli, Pseudomonas aeruginosa, B. subtilis, and Streptococcus pyogenes[29] The AgNPs of Bacillus methylotrophicus demonstrated antimicrobial activity against E. coli, Vibrio parahaemolyticus, Salmonella enterica, and Candida albicans as reported by Wang et al.[42]Bacillus pumilus AgNPs revealed antibacterial activity against E. coli, Pseudomonas aeruginosa, Streptococcus bovis, Klepsiella pneumoniae, Salmonella typhimurium, Shigella sonnei and Staphylococcus aureus.[43] It was found that Bacillus subtilis and Bacillus amyloliquefaciens AgNPs inhibited the growth of Xanthomonas oryzea as reported by Fouad et al.[44]

The main components of lemon balm EO are volatile oxygenated monoterpenes, that is, geranial, neral, citronellal, and geraniol (Abdellatif, Boudjella, Zitouni, & Hassani, 2014; Shakeri et al., 2016). This EO has shown antimicrobial potential against a wide range of gram-positive bacteria (Gutierrez, Rodriguez, Barry-Ryan, & Bourke, 2008) and fungi (Abdellatif et al., 2014; Araújo, Sousa, Ferreira, & Leão, 2003; El Ouadi et al., 2017) and also against certain gram-negative bacteria (Abdellatif et al., 2014; Djaković-Sekulić, Božin, & Smoliński, 2016; Jalal et al., 2015; Mimica-Dukic, Bozin, Sokovic, & Simin, 2004; Tyagi & Malik, 2012). Mimica-Dukic et al. (2004) have demonstrated that several gram-negative pathogens (e.g. P. aeruginosa, Salmonella Typhi, Salmonella Enteritidis, and Shigella spp.) are highly susceptible to lemon balm EO, with inhibition zones (IZ) ranging from 13.4 to 39.8 mm. These results are in accordance with the findings of Jalal et al. (2015), who reported that M. officinalis EO sufficiently inhibited the growth of P. aeruginosa (IZ: 16 mm) and Klebsiella pneumoniae (IZ: 13 mm). Similarly, the EO of M. officinalis, T. vulgaris, and O. vulgare have been shown to inhibit various gram-negative bacteria, including P. aeruginosa, E. coli, Salmonella Enteritidis, Salmonella Typhi, and Shigella sonnei (Djaković-Sekulić et al., 2016).
