چکیده مقاله :
سابقه و هدف: با توجه به تنوع بالا، کاربردهای زیست فناوری و نقش موثر میکروارگانیسم ها در ایجاد و حفظ تعادل زیست بوم، کسب اطلاعات و توجه به تنوع زیستی میکروارگانیسم ها بسیار مورد نیاز است. در این میان، باکتری‌ها و آرکی های نمک‌دوست نیز به دلیل اهمیت اقتصادی و شرایط خاص اکولوژیکی زیست بوم شان مورد توجه می باشند. این مطالعه با هدف بررسی تنوع باکتری ها و آرکی های هتروتروف غار نمکدان قشم انجام شد.مواد و روش ها: این پژوهش به صورت مقطعی با نمونه برداری از غار نمکدان قشم در آبان ماه سال 1392 انجام شد. تنوع میکروارگانیسم های هوازی هتروتروف ساکن غار با استفاده از روش کشت مورد بررسی قرار گرفت. باکتری ها و آرکی های هالوفیل و هالوتولرانت در شرایط هوازی به ترتیب در دو محیط کشت Marine Agar و MGM جدا سازی شدند. جدایه ها براساس تفاوت های ریخت شناسی و ویژگی های بیوشیمیایی اولیه تفکیک شدند. در نهایت ژن rRNA 16S برای 32 سویه توالی یابی شد.یافته ها: بین 172 سویه خالص ژن rRNA 16S برای 27 سویه ترادف یابی شد که از نظر فیلوژنتیک آرکی ها در شاخه یوری آرکیوتا و درجنس های هالوباکتریوم، هالوآرکولا، هالوفراکس، هالوکوکوس و باکتری ها در شاخه های فرمی کیوتس و باکتریوئیدس و در جنس های آلیفودینی بیوس، باسیلوس، پارالیوباسیلوس،اکویی باسیلوس، پائنی باسیلوس قرار گرفتند. از بین این سویه ها 11 سویه شباهت کمتر از 98.7 درصد با نزدیک ترین سویه استاندارد داشتند که نقطه مرزی برای ارائه گونه جدید میکروبی محسوب می شود.نتیجه گیری: قرار گرفتن جدایه های شناسایی شده در شاخه ها و جنس های مختلف نشان دهنده تنوع بالای اکوسیستم غار نمکدان قشم از نظر میکروبی است. ارایه میکروارگانیسم های بومی در گونه ها و جنس های جدید و از اکوسیستم های منحصر به فرد با معرفی محتوای ژنتیکی جدید امکان دست یابی به فرایند ها و ژن های جدید بومی را فراهم می کند.
Background & Objectives: Given the high diversity, biotechnological applications and the effective role of bacteria in making and maintaining the ecosystem balance; biodiversity research are very important. Meanwhile, the halophilic bacteria and archaea have been considered because of their biotechnological importance and specific ecological condition. In this study, we investigated the diversity of heterotrophic bacteria and archaea of Namakdan cave in Qeshm Island. Materials & Methods: This cross-sectional study was carried out by sampling from Qeshm Namakdan cave in November 2013. The diversity of the cave heterotrophic aerobic bacteria was analyzed using the culture method. Halophilic and halotolerant bacteria and Archaea under aerobic conditions were isolated by MGM and Marine agar media, respectively. Isolates were separated according to morphological differences, and primary biochemical features. Finally, 16s rRNA sequencing was performed for 32 isolates.Results: Among 172 isolates 16S rRNA sequencing was carried out for 27 strains. Phylogenetic analysis placed archaea in the euryarchaeota division and Halococcus, Haloferax, Haloarcula, Halogeometricum genus branches and bacteria in Firmicutes and Bacteroides divisions and in Aliifodinibius, Paenibacillus, Aquibacillus, Paraliobacillus, and Bacillus genus branches. Among the sequenced isolates, 11 isolates showed less than 89.7% similarity to the standard species, which is considered as a borderline point to present new microbial species. Conclusion: Placing the identified isolates in different phylogenetic divisions and genus branches demonstrates the wide microbial diversity of Qeshm Namakdan cave ecosystem. Presenting native microorganisms in new species and genera from unique ecosystems by introducing new genetic content provides access to new native genes and pathways.
