چکیده مقاله :

زمینه و هدف: فنل و مشتقات آن برای همه موجودات زنده سمی بوده و در فاضلاب پالایشگاه نفت یافت می‌شوند. جداسازی و شناسایی باکتری‌ها از فاضلاب پالایشگاه نفت به منظور شناسایی باکتری‌های تجزیه کننده ترکیبات آروماتیک مهم است. هدف از این تحقیق جداسازی و شناسایی باکتری‌ها از سیستم تصفیه فاضلاب پالایشگاه نفت تهران و تعیین میزان حذف فنل بوسیله باکتری‌ها در محیط کشت حاوی فنل بود. مواد و روش ها: مطالعه از نوع تجربی- آزمایشگاهی بود. نمونه برداری از سیستم لجن فعال تصفیه خانه فاضلاب پالایشگاه نفت تهران در دو مرحله انجام شد. ابتدا باکتری‌ها در محیط کشت حاوی فنل به مدت 3 هفته در انکوباتور دمای 30 درجه سانتیگراد به فنل خو داده شدند. سپس جداسازی و شناسایی باکتری‌ها مطابق روش استاندارد انجام شد . با کشت باکتری‌های ایزوله در محیط‌های کشت حداقل حاوی غلظت‌ های 5/0 تا 2/1گرم بر لیتر فنل به عنوان تنها منبع کربن، رشد باکتری‌ها با اندازه گیری دانسیته اپتیک در طول موج 600 نانومتر بررسی شد. غلظت فنل به روش اسپکتروفوتومتری با استفاده از واکنشگر4-آمینوآنتی پیرین در طول موج 510 نانومتر مورد سنجش قرار گرفت. یافته ها: باکتری‌های جداشده از تصفیه خانه فاضلاب پالایشگاه نفت شامل سویه‌های سودوموناس، اسینتوباکتر، اشرشیاکلی ، انتروکوکوس و انتروباکتر بودند. سویه سودوموناس قادر به حذف کامل فنل تا غلظت 9/0 گرم بر لیتر، سویه‌های اسینتو باکتر و اشرشیاکلی تا غلظت 7/0 گرم- بر لیتر فنل را به طور کامل حذف و سویه‌های انتروکوکوس و انتروباکتر تا غلظت 5/0 گرم بر لیتر فنل را به میزان صد در صد از محیط کشت حذف نمودند. بحث و نتیجه گیری: سودوموناس نسبت به دیگر باکتری‌های جدا شده از فاضلاب پالایشگاه نفت بیش‌ترین میزان تجزیه فنل را در زمان کم‌تر نشان داده است.

چکیده انگلیسی:

Background and Objective:Phenol and its derivatives are toxic to all living organism and are found in oil refinery wastewater. Isolation and identification of bacteria from oil refinery wastewater is important to identify aromatic compounds degrading bacteria. The aims of this study were isolation and identification of bacteria from Tehran oil refinery wastewater treatment system and determine amount of phenol degradation by these bacteria. Method: This experimental study was conducted by using two series of activated sludge samples collected from Tehran oil refinery wastewater treatment plant. Adaptation of bacteria to phenol was done by culturing in growth medium containing phenol at 30°C in incubator. After that isolation and identification of bacteria was done according to standard method. Isolated bacteria were cultured in growth medium containing different concentration (0.5- 1.2gL-1) of Phenol. Bacteria growth was assayed by measuring optical density at 600nm. Concentration of Phenol in the medium growth solution was measured by spectrophotometric method using 4- Amino antipyrine as color reagent at 510 nm. Findings: Pseudomonas, Acintobacter, E.coli, Enterococcus and Enterobacter spps were isolated from oil wastewater treatment plant. Pseudomonas spp. completely removed 0.9gL-1 of Phenol, Acintobacter and E.coli removed 0.7 gL-1, Enterococcus and Enterobacter removed 0.5 gL-1 of Phenol from growth solution. Discussion and conculation: Pseudomonas spp. isolated from oil refinery wastewater treatment plant has highest phenol removal rate in shorter contact time than other isolated bacteria.
