چکیده مقاله :
سابقه و هدف: بر اساس گزارش سازمان فائو سالیانه 10 درصد از محصولات غذایی تولید شده در دنیا توسط سموم قارچی آلوده می‌شوند که در این آلودگی آفلاتوکسین‌ها سهم بیشتری نسبت به سایر سموم دارند. این پژوهش با هدف ارزیابی توانایی اتصال آفلاتوکسین به لاکتوباسیلوس رامنوسوس زیرگونهGG در محیط شبیه‌سازی دستگاه گوارش انسان حاوی شیراستریلیزه به منظور کاهش سمیت آفلاتوکسینB1 انجام شد.مواد و روش‌ها: تعداد باکتری cfu/ml 1010×1 و غلظت آفلاتوکسین 5 میکروگرم بر میلی لیتر در نظر گرفته شد که در محیط شبیه سازی شده ترشحات مصنوعی دستگاه گوارش انسان تلقیح گردید. در این مطالعه 6 گروه تیمار در حضور و غیاب باکتری، شیراستریلیزه، سوسپانسیون شیره دستگاه گوارش مورد بررسی قرار گرفت. غلظت آفلاتوکسین باقیمانده توسط کروماتوگرافی مایع با کارایی بالا (HPLC) و تخلیص با ستون ایمونوافینیتی تعیین گردید.یافته ها: کاهش آفلاتوکسین B1 در تمام تیمارها با استفاده از کروماتوگرافی مایع با کارایی بالا با حد تشخیص 0.25 میکروگرم بر میلی‌لیتر و حد تعیین کمی 0.75 میکروگرم بر میلی‌لیتر اندازه‌گیری شد. مقادیر بازیافت مایکوتوکسین AFB1 بین 89 تا 94 درصد بود. منحنی درجه بندی آفلاتوکسین B1 با ضریب همبستگی 0.995 در گستره غلظتی 1 تا 10 نانوگرم بر میلی لیتر خطی بود. بیشترین و کمترین میانگین درصد حذف آفلاتوکسین B1 به ترتیب مربوط به تیمار5 و 1 ( 0.018 ±58.8 و 0.017± 13.86) بود که تفاوت معنی‌‌داری در بین شش گروه وجود داشت.نتیجه گیری: نتایج نشان داد که علاوه بر باکتری لاکتوباسیلوس رامنوسوس زیر گونه GG، شیره معده و روده کوچک نیز در کاهش یا حذف آفلاتوکسین B1 موثر می‌‌باشند.
Background & Objectives: According to the FAO annual report, 10 percent of the world's food products are contaminated with fungal toxins, among which aflatoxins have the most contribution as compared to others. This research was aimed to assess the ability of Lactobacillus rhamnosus strain GG in the reduction of aflatoxin B1 (AFB1) in a simulated human gastrointestinal tract containing sterilized milk. Materials & Methods: For this purpose, the bacterial count and aflatoxin concentration were adjusted to 1×1010 cfu/ml and 5 ppm, respectively, where artificial gastrointestinal tract discharges were inoculated in the simulated environment. In this study 6 treatment groups were assessed in the presence and absence of bacteria, sterilized milk, and gastrointestinal juice suspension. The concentration of residual aflatoxin was determined using high-performance liquid chromatography (HPLC) and purification by Immunoaffinity column. Results: The reduction of aflatoxin B1 at all treatments was determined using HPLC with a detection limit of 0.25 mg/ml and a quantification limit of 0.75 mg/ml. The mycotoxin recovery rate was between 89% and 94% for AFB1. The aflatoxin B1 calibration curve with a correlation coefficient of 0.95 was linear in the concentration range of 1 to 10 ng/ml. The highest and lowest average removal percentage of aflatoxin B1 was observed for 5 and 1 treatments (58.8 ± 0.018 and 13.86 ± 0.017) respectively, where a significant difference in removal percentage was observed among six treatment groups. Conclusion: The results indicated that beside L. rhamnosus strain GG, gastric and small intestine juices are suitable to eliminate or reduce aflatoxin B1, as well.
