In this study, first appropriate amounts of oligofructose were selected as prebiotic material and then a mixture of vegetable water produced in proportions of 20, 30 and 40% was prepared and inoculation of Lactobacillus casei strain by half McFarland method at two levels of 106 and 107 cfu/ml were performed. All physicochemical tests such as pH, acidity, Brix and microbial count were evaluated before fermentation, after 72 hours of fermentation at 37°C and during four weeks of storage at 4°C. Reduced glucose and total glucose were evaluated before fermentation, after 72 and 4 weeks of fermentation. During fermentation and storage, with increasing bacterial density and storage time, pH, Brix, reducing sugar and total sugar of probiotic beverages decreased and acidity increased significantly. The highest survival rate of probiotic bacteria during 28 days of storage related to A3B2 treatment (with bacterial density of 107 CFU/ml) was selected as the best treatment according to the results.

This research was done by purpose of investigating the effect of wastewater on accumulation of metals Pb and Cd in soil and vegetables. Method: For this purpose, sampling from soil and vegetables was performed randomly in the city of Hamedan. Sampling was done in an area irrigated with well water and in an area irrigated with wastewater. Vegetable Samples were prepared after washing and drying, powdered and prepared for experiment. Also soil samples after air-drying, sieve, and prepared for experiment. Then samples digested with acid mixture and heavy metals measured by Atomic Adsorption Spectroscopy (AAS). Finally obtained data were analyzed by SPSS 20. Findings: Results showed that wastewater had important effect on accumulation of Pb and Cd in soil and vegetables which means concentration of these metals in the soil and vegetables that was irrigated with wastewater was higher than those irrigated with well water. Also this is identified that the concentrations of Pb and Cd in studied vegetables was higher or equal to standards and Cd in the soil of both control and treatment were or equal to standards but Pb were lower than standards. Discussion and Conclusion: Since, in the treatment area, the mean concentration of Cd in scallion vegetable and mean concentration of Pb in leek vegetable is higher than standard. Therefore, in order to prevent creating problems for citizens’ health, irrigation of fields by wastewater must be prevented. Manuscript profile -

One of the ways of human bacterial contamination is to consume vegetables irrigated with water contaminated with bacteria. These two genes cause the activation of the message transmission pathway and the DNA mutation and tumorigenesis by producing the toxin Bactin. The main aim of the present study is to investigate clbB and clbN genes in Escherichia coli isolated from vegetables irrigated with surface water and urban waste. Materials and methods: Vegetables irrigated with surface water, well and urban waste were collected from three regions of Tehran. Their E.coli bacteria were isolated and identified and confirmed. Then, PCR test was performed for clbB and clbN genes of all isolated E.coli bacteria. Findings: The obtained microbial and biochemical results confirmed the E.coli bacteria isolated from the investigated vegetables. The molecular results showed that the highest and lowest frequencies for the samples that simultaneously contained both studied genes were related to vegetables irrigated with urban waste and vegetables irrigated with well water (P≤0.05). This result was almost the same for the vegetables of all three studied regions. Conclusion: Considering the high frequency of E.coli bacteria isolated from vegetables irrigated with municipal waste and in order to prevent bacterial infection and consequently colorectal cancer, complete disinfection of vegetables and non-irrigation of vegetables in areas with waste are suggested. Keywords: E.coli, clbB, clbN, Vegetables, Urban waste, Surface water. Manuscript profile -

Identified species and their hosts were as follow: Sinella tenebricosa (Entomobryidae) and Proisotoma minuta (Isotomidae) from African violet, and Ceratophysella sp. (Hypogastruridae) from greenhouse cucumber and parsley. Studies indicated that these collembolans reach to high density, with more damage on plants, in greenhouses and pots with higher humidity and shorter irrigation periods. In the infested plants, secondary roots were devoured completely and the plants could be easily infected by pathogens, due to collembolan damages to plant crown. Among the indicated species, only P. minuta was recorded from Iran, and Ceratophysella sp. might be a new species to the world. Manuscript profile -

Nowadays, due to the antimicrobial properties of EOs, they have been used as natural food preservatives. In this study, initial experiments were performed in order to elucidate the minimum bactericidal concentration of Rosmarinus officinalis L.EO on Escherichia coli O157:H7, Salmonella enterica and Listeria monocytogenes. Thereafter, PMA-qPCR was applied in order to selectively quantify living cells within a bacterial population treated with rosemary EO. Inactivation was obtained at EO concentrations of 1%, 0.45%, 0.9% for L. monocytogenes, E. coli O157:H7 and S. enterica, respectively. L. monocytogenes were totally killed within 45 min while it took 90 min for E. coli O157:H7and S. enterica. It was concluded that rosemary EO has the potential to be used as a natural food additive or bio-preservative since it was able to irreversibly inactivate the three tested pathogens at lower concentrations and short exposition times in comparison with the other EOs. In addition, PMA-qPCR approach proved quantitatively precise and specific to selectively detect live pathogenic bacteria in vegetables following inactivation with rosemary EO. Manuscript profile -

Their entrance into food chain is a serious health hazard to humans. This study was conducted to determine the concentrations of Cadmium, Zinc and Manganese in root, stalk and leaf portions of spinach and tomato. For this reason, during 2014 in Hamedan city, 3 farms with 5 repetitions from each farm were sampled. Samples were subjected to acid-digestion and the concentrations of the elements were assayed by inductively coupled plasma (ICP). According to the results, the average concentrations of heavy metals in root, stalk and leaf of spinach was estimated at: cadmium, 0.14, 0.24, 0.34 mg/kg, zinc, 15.53, 24.82, 35 mg/kg and manganese, 26.59, 24.42, 45.38 mg/kg, respectively. The data for the tomato samples were: cadmium, 16.20, 24.42, 33.81 mg/kg, Zinc, 21.48, 39.74, 52.92 mg/kg and manganese, 26.60, 42.41, 61.90 mg/kg, respectively. The mean concentration of cadmium and manganese in spinach and tomato showed a significant difference with the WHO/FAO standard limit. However, in the case of zinc the difference was insignificant. It was concluded that in this experiment the spinach and tomato samples were polluted with higher concentration of cadmium and manganese than the approved limit of WHO/FAO and therefore was found risky for the consumers.

This study was conducted to examine the accumulation of nitrate and nitrite in vegetables of Shahre-Kord retails. For this purpose, a total of 222 fresh vegetables samples were collected in winter 2011 and summer 2012 and were analyzed for the accumulation of nitrate and nitrite. Results showed a vast deviation between the mean concentrations of nitrate. In other words, the nitrate accumulation for mint was 310.9 mg/kg fresh weight (FW) and for savory was estimated at 3309.1 mg/kg FW. Nitrate accumulation in more than 85% of the vegetable samples was below the approved limit of 2500 mg/kg FW; meanwhile in savory it was higher than 3000 mg/kg FW. Moreover it was revealed that in comparison with nitrate, the mean value of nitrite accumulation was remarkably low (below 1.65 mg/kg FW). According to the results, the nitrate accumulation was significantly (P<0.05) higher in the samples obtained during the summer, but in the case of nitrite the results were reversed. In conclusion the levels of nitrate and nitrite in vegetables of ShahreKord retails were unlikely to pose any health hazard to the general population; nonetheless, the application of efficient techniques for decreasing the nitrate and nitrite accumulation in vegetables is recommended.

Therefore, the intake of these products can threaten human health. The aim of this study was to determine nitrite and nitrate in cucurbits and vegetables cultivated in plains of sothern and eastern parts of Kermanshah. For this purpose, a total number of 330 samples was examined for determination of nitrate and nitrite. The samples were analyzed according to the instructions provided by the Institute of Standards and Industrial Research of Iran (No. 4106). The results showed that there are significant differences in the mean value of nitrite in vegetables and cucurbits, in the sampling locations (P<0.01). However, this difference was not significant (P>0.05) in the case of nitrate. The highest level of nitrite was estimated at 6.05±2.1 and 6.12±0.845 mg/kg in radish tubers and the lowest level was estimated at 0.1±0.022 and 0.174±0.085 mg/kg in cucumber samples in Mahidasht and Drood and Framan plains, respectively. In addition, the highest amount of nitrate in the Mahidasht plain was determined in spinach (392.11 ± 21.17 mg/kg) and in the Drood and Framan plain was observed in radish tubers (316.94 ±158.02 mg/kg). The lowest levels of nitrate in the both sampling areas were determined in tomatoes (11.42 ± 3.56 and 9.1±5.2 mg/kg, respectively). Moreover, a significant difference (P<0.01) was observed in the mean quantity of nitrate and nitrite in the different vegetables or cucurbits. It was concluded that the level of nitrite in some vegetables and cucurbits was higher than acceptable limit. Therefore, it is essential to reduce the application of nitrogen fertilizers in these areas. Manuscript profile -

The bacterium also has the ability to the production of heat resistant enterotoxin. The present study was done to assess the prevalence rate, antibiotic resistance pattern, and frequency of enterotoxin encoding genes in methicillin-resistant S. aureus strains isolated from vegetable and salad samples. In this study, 485 samples of vegetables and salad were collected and immediately transferred to the laboratory. The microbial culture was used to isolate S. aureus, and methicillin-resistant strains were approved using cefoxitin and oxacillin disks. Antibiotic resistance patterns and frequency of enterotoxin encoding genes were analyzed using disk diffusion and PCR methods, respectively. The prevalence rate of methicillin-resistant S. aureus in vegetable and salad samples were 7.2% and 8.51%, respectively. Methicillin-resistant S. aureus strains had the highest antibiotic resistance against penicillin (100%), co-amoxiclav (100%), ampicillin (100%) and ceftriaxone (100%) antibiotics. The prevalence of resistance against imipenem (10.52%) and chloramphenicol (23.68%) was lower than other antibiotics. SEA (63.15%) and SEB (52.26%) were the most frequently detected enterotoxins in methicillin-resistant S. aureus strains. The simultaneous presence of multiple enterotoxin encoding genes and multiple resistance against several antibiotics in methicillin-resistant S. aureus strains isolated from vegetable, and salad samples represent an important health-related concern in this kind of food samples. Preventing uncontrolled administration of antibiotics can reduce the risk of enterotoxigenic methicillin-resistant S. aureus enterotoxin in vegetables and salads. Manuscript profile -
