Under intensive aeration (1.3 l/l min) the associated growth of Rhodotorula rubra GED2 and Lactobacillus casei subsp. casei in cheese whey ultrafiltrate (55 g lactose/l) proceeded effectively for both cultures with production of maximum carotenoids (12.4 mg/l culture fluid). For maximum amount of carotenoids synthesized in the cell, the yeast required more intensive aeration than the aeration n...
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...
سابقه و هدف: طوفانهای گردوغبار میتوانند آلایندههای ذرهای را به فاصلههای بسیار دور و در بعضی از موارد به هزاران کیلومتر دورتر از منبع تولید انتقال دهند. این طوفانها میتوانند حجم بسیار زیادی بیوآئروسل از جمله گونههای قارچی عامل عفونتهای تنفسی و آلرژیک را به همراه خود داشته باشند. هدف از این مطالعه، تعیین تأثیر طوفانهای گردوغباری در انتقال انواع گونههای قارچی در هوای اتمسفری شهر ایلام است. مواد و ...
Rhodotorula species live in the environment, but can also colonize human epithelium, as well as respiratory, and gastrointestinal tracts. Reports of infection, especially in the past 2 decades, have noted increasing numbers of Rhodotorula infections, particularly in immunocompromised hosts, leading it to be considered emerging opportunistic pathogen. The major risk factors for infection were pr...
Carotenoids from some of the coloured yeasts like Rhodotorula, Phaffia rhodozyma have attracted commercial interest as a natural pigment for foods. Red yeast isolated from the contaminated PDA plate yeast has been found to produce carotenoids. This red was characterized and designated as Rhodotorula glutinis DFR-PDY. The isolated crude pigment from the red yeast Rhodotorula glutinis DFR-PDY was...
Yeast exopolysaccharide (EPS) are composed of unique sugar units, which offers an interesting perspective with respect to various food applications. This study aimed to characterize the EPS from Rhodotorula minuta BIOTECH 2178. Toxicological assessment of the EPS was investigated to ensure that it is safe for human consumption. The yeast EPS revealed high total sugar composition (59.2162-47%) a...
Rhodotorula yeasts were isolated from various local sources in Damascus, Syria, during 2012 and 2013. Fifty isolates (23 from leaves trees, 13 from different soils, 6 from different meats, 6 from dairy products, 1 pickle and 1 traditional sweet) were identified using API 20C AUX system. Isolated yeasts were classified into three Rhodotorula species: R. mucilaginosa, R. glutinis and R. minuta re...
Stereospecifically labeled mevalonic acid was incorporated into the carotenoids of Rhodotorula. The randomized results are discussed in relation to mechanisms proposed for the conversion of isopentenyl pyrophosphate to dimethylallyl pyrophosphate and the prenol transferase enzyme system to Rhondotorula rubra.
ایجاد فضاهای فعال و زنده شهری در کنار شهرها، امری اجتنابناپذیر میباشد. آمایش سرزمین در مکانیابی عرصههای مناسب برایتوسعه جنگل و فضای سبز براساس ویژگی اکولوژیکی آنها به ما کمک میکند. انتخاب گونههای درختی در سطح شهر از وظایف مهمکارشناسان فضای سبز و جنگلداری شهری میباشد و در اینمیان انتخاب گونههای گیاهی مناسب از اساسیترین بخشهای یک طرحفضای سبز موفق است. منطقه مورد مطالعه در دامنههای البرز جنوبی در ...
