This study aimed to describe the inhibitory activity of Cell-Free Supernatant (CFS), planktonic cells, and biofilm form of Lactobacillus strains isolated from native dairy sources on food pathogens. \u0000Methods: Antibacterial activities of the CFS of Lactobacillus strains were assessed by the microplate method and via violet staining, and in planktonic cells, and biofilm forms were performed by the spread plate method. \u0000Results: The results showed that despite the large differences in biofilm formation power among the strains, most of them can produce biofilm. Lactobacillus delbrueckii subsp. bulgaricus, Lactobacillus plantarum, Lactobacillus delbrueckii subsp. Lactis, Lactobacillus brevis, and Lactobacillus lactis subsp. lactis formed the strongest biofilm, respectively. Planktonic states reduce the pathogens bacterial by about 1.43 log, but in biofilm forms, decreased Listeria monocytogenes by about 4.8 log compared to the control, and in the case of Pseudomonas aeruginosa, a growth reduction of about 2.8 logs was observed. \u0000Conclusion: According to the study, biofilm produced by probiotic strains can be considered a new approach for biological control.

This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. \u0000Methods: Two sets of specific primers were designed based on the 12S rRNA gene sequences of pig and cattle species from GenBank. The primers were validated by using the DNA extracted from nine different chordates, including pig, cattle, chicken, bata fish, bat, toad, African parrot, rat, and human origin. Annealing temperature ranging from 46-54°C for 30 seconds and template DNA 1:10 serial dilutions ranging from 10 to 0.00001 ng/µl were employed for primer annealing and sensitivity analysis. Samples were analyzed using optimized Polymerase Chain Reaction (PCR) conditions. \u0000Results: The most intense expected DNA bands of pig and cattle were produced at 50°C. Under that optimized annealing temperature pig and cattle-specific primers did not anneal with the DNA of other chordates. Total extracted DNA 0.001 ng and 0.01 ng of pig and cattle respectively containing the mitochondrial DNA (mtDNA) was successfully detected. \u0000Conclusion: These findings indicate that the newly designed primer pairs can be used to detect pig and cattle derivatives in various processed food and feed products.","PeriodicalId":37437,"journal":{"name":"Journal of Food Quality and Hazards Control","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46673053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work focused on proximate compositions (moisture, protein, fat, and ash) and risk assessment of lead in two common fishes (L. rohita and B. gonionotus) collected from river and farms of Bagerhat, Bangladesh. Furthermore, effect of freezing condition on fish lipid was studied. \u0000Methods: Proximate compositions of the fish samples were determined according to conventional methods. The lead contents were analyzed by wet digestion method using an atomic absorption spectrophotometer. The health risks models such as Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI), and Target Cancer Risk (TCR) were conducted for health risk assessment of the local people. Data were analyzed using SPSS software (version 16.0). \u0000Results: A positive correlation was found between moisture-protein and lipid-ash of the L. rohita fish. Besides, a positive relation was observed in ash-moisture, and lipid-protein for B. gonionotus. The lead content in river L. rohita, farm L. rohita, river B. gonionotus, and farm B. gonionotus was observed as 9.00, 9.20, 8.29, and 6.39 mg/kg, respectively. The lead content found in the fish species were above the permissible limit. The TCR revealed the carcinogenic effects to the local people due to exposure of lead. \u0000Conclusion: This study reflects some data about proximate values of L. rohita and B. gonionotus fishes.
