چکیده مقاله :
سابقه و هدف: همواره شناسایی و تعیین ویژگی های جدایه های لاکتیکی زیست بوم هایی که کمتر مورد مطالعه قرار گرفته اند احتمال مواجهه با باکتری های دارای قابلیت های منحصر به فرد را در پی داشته است. این مطالعه با هدف شناسایی مولکولی و ارزیابی خواص ضد باکتریایی جدایه لاکتیکی غالب خمیرترش آرد جو انجام شد. مواد و روش ها: در این مطالعه تجربی پس از تهیه خمیرترش از آرد کامل جو، باکتری اسید لاکتیک غالب آن جداسازی گردید. در ادامه، جدایه لاکتیکی با توالی یابی محصولات PCR، شناسایی شد و ویژگی های ضد باکتریایی آن و پالیده کشت خام و خنثی شده فازهای رشد لگاریتمی و سکون جدایه یاد شده به ترتیب بر اساس روش های انتشار چاهک و میکرودایلوشن در برابر برخی از شاخص های باکتریایی غذازاد مورد ارزیابی قرار گرفت. یافته ها: توالی یابی محصولات PCR، موجب شناسایی پدیوکوکوس پنتازاسئوس به عنوان جدایه لاکتیکی غالب خمیرترش آرد جو شد. این جدایه از بین شاخص های باکتریایی مورد مطالعه، به شکل معنی داری (0.05>P) دارای اثر آنتاگونیستی بیشتری نسبت به لیستریا مونوسیتوژنز بود. علاوه بر این، پالیده خام حاصل از فاز رشد لگاریتمی جدایه یاد شده نسبت به سایر پالیده ها از فعالیت باکتریوسینی و همچنین تاثیر ضد باکتریایی بیشتری بر روی شاخص های باکتریایی غذازاد برخوردار بود. نتیجه گیری: پدیوکوکوس پنتازاسئوس جدا شده از خمیرترش آرد جو و پالیده های کشت آن دارای خاصیت بازدارندگی مناسبی در برابر شاخص های باکتریایی غذازاد مورد مطالعه بود. بنابراین می توان از این جدایه به عنوان کشت آغازگر و یا کشت همراه در فرآوری محصولات غذایی تخمیری به جای نگهدارنده های شیمیایی و آنتی بیوتیک های سنتزی با هدف بهبود ماندگاری و ارتقاء سلامت این فراورده ها استفاده نمود.
Background & Objectives: Usually identification and characterization of ecosystems isolates of lactic acid bacteria (LAB) which have been rarely studied lead to obtaining LAB with unique characteristics. The aims of this study were molecular characterization and evaluation of the antibacterial properties of dominant LAB isolated from whole barley sourdough. Materials & Methods: In this experimental study, first the sourdough was prepared from the whole barley flour, and subsequently its dominant LAB was isolated. LAB isolate was identified by sequencing of PCR products. Antibacterial properties of the isolate and its cell free culture filtrate (CCF) which was obtained from logarithmic and stationary phases as crud and naturalized form were also investigated for some food-borne indicator bacteria using well diffusion and microdilution methods, respectively. Results: Sequencing results of PCR products lead to identification of Pediococcus pentosaceus as the dominant LAB in whole barley sourdough. This LAB isolate had more antagonistic effect (p<0.05) on Listeria monocytogenes than other indicator bacteria. Furthermore, crud CCF obtained from logarithmic phase of the isolate had the highest bacteriocin activity and antibacterial ability in comparison to other CCFs. Conclusion: Whole barley sourdough P. pentosaceus isolate and its CCF have proper antibacterial properties against food-borne indicator bacteria used in this study. Therefore, P. pentosaceus has high potential to be used as microbial starter or adjunct culture in processing fermented foods instead of chemical preservatives or antibiotics in order to increase shelf life and safety of these products.
