Abstract:

Background: Our aim was to compare microorganism detection between standard culture (Ctx) and next generation sequencing (NGS) in patients undergoing surgery for nephrolithiasis; we prospectively compared both urine and stone culture results using these two techniques. Methods: We prospectively compared microorganism detection of urine and stone cultures using Ctx versus NGS in patients undergoing surgery for nephrolithiasis. We analyzed preoperative voided urine (Voided) using both Ctx and NGS. Intraoperatively, renal stone (Stone) cultures were analyzed with Ctx and NGS. The primary outcome

Abstract:

In the 1960s, microbiology and culture collection experts met several times to develop a strategic plan to foster microbial culture collections. They quickly recognised that statistics on the activities of culture collections worldwide were not available and that there was a need for a ?world directory of collections of cultures of microorganisms? that accumulated information on culture collections. It was obvious also that a world data centre for microorganisms was required to develop and maintain the directory.

Abstract:

Marine microorganisms have drawn great attention as novel bioactive natural product sources, particularly in the drug discovery area. Using different strategies, marine microbes have the ability to produce a wide variety of molecules. One of these strategies is the co-culturing of marine microbes; if two or more microorganisms are aseptically cultured together in a solid or liquid medium in a certain environment, their competition or synergetic relationship can activate the silent biosynthetic genes to produce cryptic natural products which do not exist in monocultures of the partner microbes.

Antagonism is the interaction that occurs when a microorganism interfere with the growth of other microorganisms. One of the microorganisms that have antagonistic ability is yeast. The research aims to determine the ability of antagonism yeast derived from the leaves of teak (Tectona grandis) as an agent for controling mold from poultry feed is Aspergillus sp., Fusarium sp., and Penicillium sp. Tests carried out using the method of antagonism co-culture in medium Potato Dextrose Broth (PDB) during the four days of incubation temperature of 27-28°C.

Abstract:

Soil microorganisms have a significant effect on microbiological cenosis. Such communities are called the root micro-flora of the plant. All organisms in the microflora are divided into two groups: rhizoplane, living directly on the root system of the plant, and rhizosphere, developing in the root area of the plant. The intensive population of the root and root zones of a plant is primarily associated with the release (exosmosome) of organic substances or exudates formed during the life of the plant. The plant microflora includes not only symbiotic and commensalithic types of interaction, but

AbstractDue 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 in comparison with the pure culture of F. langsethiae in the same conditions. The microbial growth of both microorganisms was assessed using three different methods: dry weight, DOPE-FISH, and D

Abstract:

When cells are cultured in a Petri dish, the adherent cells attach to the bottom of the dish; whereas, the nonadherent cells float in the culture medium. It was observed that nonadherent cells could be induced to adherent-like cells when cultured in an engraved plastic dish (biosimulator). The adherence of these cells to the engraved surface could be prevented with inhibitors specific for adhesion. It was also observed that culturing microorganisms of the environment in a biosimulator induced weak adhesion and high proliferation. Analysis of the microbiome using 16S rRNA profiling demonstrated

A composed mixed acidophilic, iron-oxidizing culture (FIGB) and a thermo-acidophilic enrichment culture (TK65) were used to evaluate microbial iron(III) reduction coupled to oxidation of reduced inorganic sulfur compounds (RISCs) under high pressure. Experiments were done in batch culture in high pressure vessels at 1 and 100 bar. Microbial abundance and activity were determined by measuring iron(II) concentration, direct cell counting, T-RFLP and quantitative real-time PCR. The data indicate that both cultures are able to reduce soluble iron(III) by oxidation of sulfur compounds under anaerob

ABSTRACT In the aftermath of the anthrax letters of 2001, researchers have been exploring various analytical signatures for the purpose of characterizing the production environment of microorganisms. One such signature is stable isotope ratios, which in heterotrophs, are a function of nutrient and water sources. Here we discuss the use of stable isotope ratios in microbial forensics, using as a database the carbon, nitrogen, oxygen, and hydrogen stable isotope ratios of 247 separate cultures of Bacillus subtilis 6051 spores produced on a total of 32 different culture media.
