Results showed that these ZnO/Nylon 6 nanofiber mats had excellent antibacterial efficiency (99.99%) against both the Gram-negative Escherichia coli and Gram-positive Bacillus cereus bacteria. In addition, they exhibited good detoxifying efficiency (95%) against paraoxon, a simulant of highly toxic chemicals.

The resultant silver nanoparticle-filled nylon 6 hybrid nanofibers show an excellent fibrous structure (fiber diameter at 50–150 nm), with narrow size 2–4 nm silver nanoparticles uniformly dispersed throughout the nylon 6 matrix.

The Food and Drug Administration currently has a 5‐log reduction standard for E. coli O157:H7 and other vegetative pathogens in acidified pickle products. For fermented vegetables, which are acid foods, there is little data documenting the conditions needed to kill acid resistant pathogens. To address this knowledge gap, we obtained 10 different cucumber fermentation brines at different stages of fermentation from 5 domestic commercial plants. Cucumber brines were used to represent vegetable fermentations because cabbage and other vegetables may have inhibitory compounds that may affect survival. The 5‐log reduction times for E. coli O157:H7 strains in the commercial brines were found to be positively correlated with brine pH, and ranged from 3 to 24 d for pH values of 3.2 to 4.6, respectively. In a laboratory cucumber juice medium that had been previously fermented with Lactobacillus plantarum or Leuconostoc mesenteroides (pH 3.9), a 5‐log reduction was achieved within 1 to 16 d depending on pH, acid concentration, and temperature. During competitive growth at 30 °C in the presence of L. plantarum or L. mesenteroides in cucumber juice, E. coli O157:H7 cell numbers were reduced to below the level of detection within 2 to 3 d. These data may be used to aid manufacturers of fermented vegetable products determine safe production practices based on fermentation pH and temperature.}, number={3}, journal={Journal of Food Science}, author={Breidt, F. and Caldwell, J.

Influent samples were assayed with species-specific primers and dual-labeled probes for human, bovine, swine, dog, cat, Canada goose and white-tailed deer to detect and quantify eukaryotic mtDNA contributors to local municipal wastewaters. Human (mean = 9.6 × 104 copies/ml) and dog (mean = 5.3 × 102 copies/ml) mtDNA were detected in all 24 samples (12 samples/site). Bovine and swine mtDNA were detected sporadically and at lower levels than human mtDNA, means = 3.0 × 104 and 9.5 × 102 copies/ml, respectively. Domestic cat, Canada goose and white-tailed deer were detected only once in 24 samples. Mitochondrial DNA concentrations were compared to other bacterial, chemical and spectrophotometric parameters. Human mtDNA was positively correlated with ammonia concentration (P = 0.01) and initial OD600 reading (P = 0.02) at one WWTF. Bovine mtDNA was positively correlated with biological oxygen demand (BOD) (P = 0.02), final DNA concentration (P = 0.03), initial and final humic acid concentrations (P = 0.01, P = 0.01), and final OD600 (P = 0.03) at one WWTF and total suspended solids (TSS) (P = 0.04, P = 0.09) at both facilities.

Amplification of eukaryotic mitochondrial DNA identifies the fecal source directly and can be used in conjunction with other intestinal microbial methods to characterize effluents. Species-specific primers and dual-labeled probes for human, swine, and bovine NADH dehydrogenase subunit 5 (ND5) genes were created for multiplex real-time PCR in feces and effluent slurries. The linear range of the multiplex assay was 10(2)-10(7) mtDNA copies for human, bovine, and swine effluent in combination (equal volumes). PCR amplification efficiencies for bovine, human, and swine mtDNA when assayed in combination were 93, 107, and 92% respectively. Linear regression correlation coefficients (r2) were 0.99 for all standard curves except for human mtDNA in combination (r2 = 0.95). Multiplex amplification of bovine, human, and swine mtDNA (ND5) exhibited no cross-reactions between the effluents from three species of interest. Also, no cross-reactions were observed with effluents of other vertebrates: sheep, goat, horse, dog, cat, Canada goose, broiler, layer, turkey, and tilapia. Performed as a blind test, the PCR operator was able to correctly identify all but two effluent challenge samples (10/12 or 83% correct) with no false positives (22/22 or 100% correct). The multiplex assay had a tendency to detect the species of highest mtDNA concentration only. Better detection of all three species in a combination of human, bovine, and swine effluents was accomplished by running each real-time PCR primer/ probe set singly. Real-time PCR detection limit was calculated as 2.0 x 10(6) mitochondrial copies or 0.2 g of human feces per 100 mL effluent. Some carry-over mtDNA PCR signal from consumed beef, but not pork, was found in feces of human volunteers.}, number={9}, journal={Environmental Science & Technology}, publisher={American Chemical Society (ACS)}, author={Caldwell, Jane M. and Raley, Morgan E. and Levine, Jay F.}, year={2007}, month={May}, pages={3277–3283} }
