Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...

Uncultured microorganisms comprise the majority of the planet's biological diversity. Microorganisms represent two of the three domains of life and contain vast diversity that is the product of an estimated 3.8 billion years of evolution. In many environments, as many as 99% of the microorganisms cannot be cultured by standard techniques, and the uncultured fraction includes diverse organisms t...

BACKGROUND Although the pathologic examination of cardiac valves remains the reference standard for the diagnosis of infective endocarditis, the detection of microorganisms often poses a challenge for pathologists. This can be done by use of nonspecific histochemical stains or by immunohistochemical analysis, but specific antibodies are often not available. We describe a novel method for the de...

Introduction: Diagnosis of infection based on blood culture alone is not a suitable method, but it is important to understand the clinical diagnosis for interpreting blood cultures. The goal of this study was to determine blood culture contamination and the type of microorganisms in false and real positive cases in patients admitted at Avicenna Hospital. Methods: This cross sectional study was...

Background: Diabetic foot ulcers (DFUs) are responsible for days of costly hospitalization and are the major cause of medical lower limb amputations. Determining the appropriate antimicrobial therapy for DFUs is highly dependent on recognizing the microorganisms that cause them. Many reports have indicated that there has been a remarkable increase in antibiotic resistance.<br /...

Delays in the identification of microorganisms are a barrier to the establishment of adequate empirical antibiotic therapy of bacteremia. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) allows the identification of microorganisms directly from colonies within minutes. In this study, we have adapted and tested this technology for use with blood culture...

In this study microorganisms from Antarctic soils were isolated using different selective nutrient media. The soils were collected from different habitats of Livingston Island. The microorganisms were isolated and purified to pure culture. The isolated microorganisms were micro-morphologically and macromorphologically characterized. The results obtained suggested that despite the extreme Antarc...

Due to contamination of barley grains by Fusarium langsethiae, T-2 toxin can be present in the brewing process. It has been observed that the presence of the yeast Geotrichum candidum during malting can reduce the final concentration of this mycotoxin in beer. In this work, a co-culture method was carried out for both microorganisms in order to evaluate the effect on T-2 mycotoxin concentration...
