چکیده مقاله :
سابقه و هدف: استفاده روزافزون از فرآورده‌های غذایی صنعتی به جای محصولات سنتی، موجب افزایش حذف باکتری‌های پروبیوتیک می شود. این مطالعه با هدف جداسازی، شناسایی مولکولی و ارزیابی ویژگی های پروبیوتیکی لاکتوباسیلوس های غالب در خمیرترش آرد کامل گندم انجام شد. مواد و روش ها: در این مطالعــه تجربی پس از جداسازی و شناسایی لاکتوباسیلوس های غالب خمیرترش آرد کامل گندم، ویژگی های پروبیوتیکی آنها شامل زنده مانی در شرایط شبیه سازی شده دستگاه گوارش، اثرات ضد میکروبی در برابر استافیلوکوکوس اورئوس، لیستریا منوسیتوژنز، اشریشیا کلی، قابلیت تجمعی بر ضد اشریشیا کلی به عنوان یک عامل عفونی روده و همچنین مقاومت این جدایه ها در برابر برخی از آنتی بیوتیک های رایج مورد بررسی قرار گرفت. یافته ها: توالی یابی محصولات واکنش زنجیره ای پلی مراز، منجر به شناسایی لاکتوباسیلوس های اسیدوفیلوس، پلانتاروم، ساکی و برویس به عنوان لاکتوباسیلوس های غالب خمیرترش آرد کامل گندم شد. از میان این چهار جدایه، لاکتوباسیلوس پلانتاروم دارای بیشترین زنده مانی در شرایط شبیه سازی شده دستگاه گوارش بود. همچنین قطر هاله عدم رشد هر سه باکتری بیماری زا در مجاورت لاکتوباسیلوس پلانتاروم و لاکتوباسیلوس برویس به شکل معنی داری از دو جدایه لاکتیکی دیگر بیشتر بود. مقایسه قابلیت تجمعی جدایه های لاکتیکی بر ضد اشریشیا کلی نیز نشان داد که لاکتوباسیلوس برویس و لاکتوباسیلوس پلانتاروم از توانمندی بیشتری در این خصوص برخوردار می باشند. همچنین این دو جدایه به همراه لاکتوباسیلوس اسیدوفیلوس در برابر آنتی بیوتیک های استرپتومایسین، کانامایسین، ونکومایسین و نالیدیکسیک اسید مقاومت نشان دادند. نتیجه گیری: لاکتوباسیلوس برویس و لاکتوباسیلوس پلانتاروم جدا شده از خمیرترش آرد کامل گندم از قابلیت بالایی برای استفاده به عنوان باکتری های پروبیوتیک در مصارف مختلف غذایی و دارویی برخوردار می باشند.
Background & Objectives: Highly demands of consumption of industrial food products has led to removal of probiotic bacteria from daily diet. The aim of this study was evaluating the probiotic properties of dominant Lactobacillus isolated from whole wheat sourdough. Materials & Methods: In this experimental study, after isolation of dominant Lactobacillus from whole wheat sourdough, the isolates were identified by polymerase chain reaction (PCR). Probiotic properties of these isolates, including survival in simulated conditions of gastrointestinal tract, antimicrobial effects against prototype bacteria (Staphylococcus aureus, Listeria monocytogenes and Escherichia coli), the ability of co-aggregation with E. coli as an infection agent of intestine and resistance of these isolates against some of routine antibiotics were also investigated in this study. Results: Sequencing of the PCR products led to identification of Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus sakei and Lactobacillus brevis as dominant Lactobacillus in whole wheat sourdough. Among the mentioned isolates, Lactobacillus plantarum showed the maximum survival in simulated conditions of gastrointestinal tract. Inhibition zone diameter of three pathogenic bacteria in the presence of Lactobacillus plantarum and Lactobacillus brevis were significantly more than the others. Comparison between co-aggregation ability of isolated Lactobacillus with E. coli showed that Lactobacillus brevis and Lactobacillus plantarum were more effective. Furthermore, these strains along with L. acidophilus were resistant to Streptomycin, Kanamycin, Vancomycin and Nalidixic acid.Conclusion: Lactobacillus brevis and Lactobacillus plantarum isolated from whole wheat sourdough are highly useful to be uses as probiotic bacteria in food and medicinal applications.
