رها شدن گاز so2 در اثر احتراق سوخت های فسیلی یکی از علل اصلی آلودگی زیست محیطی و بیماری های تنفسی می باشد. عمده ترین ماده گوگردی موجود در نفت خام و برش های آن به صورت دی بنزوتیوفن و مشتقات الکیله آن می باشد. در گوگردزدایی زیستی، حذف گوگرد از برش های نفتی با استفاده از باکتری ها توسط محصولات ژن هایabc dsz که اولین بار از باکتریrhodococcus erythropolis strain igts8 جدا شدند از طریق مسیرمتابولیکی ...
Astaxanthin is a carotenoid pigment extensively used in various industries. Rhodotorula sp. CP72-2, isolated from Calotropis gigantea, showed potential astaxanthin production. In this study, strain CP72-2 was identified as putative new species the genus based on 26S rRNA gene sequence (98% identity). It first microbial source for producing astaxanthin. Strain screened its production and quantif...
Yeasts of Rhodotorula genus have been reported to show endophytic colonization in different plants. Some of the Rhodotorula species are found to exhibit plant growth promoting activities and also have been reported to protect plants against invading pathogens. A yeast strain closely related to Rhodotorula mucilaginosa was isolated from the endosphere of Typha angustifolia collected from a Urani...
Biosynthesis of biodegradable polymers polyhydroxyalkanotes (PHAs) have been studied extensively in wild type and genetically modified prokaryotic cells, however the content and structure of PHAs in wild type yeasts is not well documented. The purpose of this study was to screen yeast isolates collected from different ecosystems for their ability to accumulate PHAs. Identification of the isolat...
Article history: Received: 29 May 2013 Accepted: 21 Aug 2013 Available online: 12 Oct 2013 ZJRMS 2015 Feb; 17(2): 52-56 Background: Rhodotorula is characterized by the absence of ballistoconidia, fermentation ability, and starch-like compounds. Biology of the species is not well-identified; therefore molecular identification is required. Sequence analysis of the D1/D2 region can be used for the...
There is a current need to develop low-cost strategies to degrade and eliminate industrially used colorants discharged into the environment. Colorants discharged into natural water streams pose various threats, including: toxicity, degradation of aesthetics and inhibiting sunlight penetration into aquatic ecosystems. Dyes and colorants usually have complex aromatic molecular structures, which m...
مطالعه ی حاضر به منظور جداسازی و شناسایی ریزوباکتری های متحمل به سرب که قادر به ارتقای رشد گیاهان تحت شرایط بروز تنش فلزات سنگین بوده و از توانایی افزایش زیست فراهمی سرب برای گیاهان پالایش دهنده ی خاک های آلوده به این فلز سنگین برخوردار هستند و همچنین ارزیابی تأثیر آن ها بر جذب سرب توسط گیاه آفتابگردان (helianthus annus l.) در شرایط گلخانه به اجرا در آمد. این مطالعه در یک خاک آلوده در مجاورت مع...
Previously, Rhodotorula glutinis was reported to produce a large amount of exocellular mannan, having a repeating unit of -->3)-D-Manp-(1-->4)-D-Manp-(1-->. Recently, we found that antigenic polysaccharides of Leptospira biflexa serovar patoc strain Patoc I have the same repeating unit and cross-react with antisera raised against extended strains of other leptospires (K. Matsuo, E. Isogai, and ...
