2. Anti-Candida and anti-quorum sensing activity of airborne microorganisms detected by a rapid method
Abstract INTRODUCTION: Introducing new antibiotics to the clinic is critical. METHODS: We adapted a plate method described by Kawaguchi and coworkers in 20131 for detecting inhibitory airborne microorganisms. RESULTS: We obtained 51 microbial colonies antagonist to Chromobacterium violaceum, purified and retested them, and of these, 39 (76.5%) were con

3. An original method for producing acetaldehyde and diacetyl by yeast fermentation
Abstract In this study a natural culture medium that mimics the synthetic yeast peptone glucose medium used for yeast fermentations was designed to screen and select yeasts capable of producing high levels of diacetyl and acetaldehyde. The presence of whey powder and sodium citrate in the medium along with manganese and magnesium sulfate enhanced both biomas

4. Biodiversity of Antimicrobial-Producing Actinomycetes Strains Isolated from Dry Dipterocarp Forest Soil in Northeast Thailand
The increasing use of antibiotics has led to the development of drug-resistant microorganisms. The emergence of resistant strains has compromised the treatment and control of infectious diseases. As a result, the search and development of a novel class of antibiotic drugs are required. Actinomycetes have been recognized as a richest source of secondary metab

5. Activity of Fabaceae species extracts against fungi and Leishmania: vatacarpan as a novel potent anti-Candida agent
AbstractLeishmaniasis and fungal infection treatment efficacy is limited by toxicity and ever increasing resistance to available drugs, requiring development of alternative compounds. The richness of Cerrado plant antimicrobial secondary metabolites justifies screening of Fabaceae species extracts: Enterolobium ellipticum Benth., Sclerolobium aureum (Tul.) B

6. Screening of native yeast from Agave duranguensis fermentation for isoamyl acetate production
In this work, fifty yeast strains, isolated from the spontaneous alcoholic fermentation of Agave duranguensis to produce mezcal, were tested using the double coupling system. These yeasts were from the genera Pichia, Torulaspora, Saccharomyces, Kluyveromyces, Deckera, Hanseniaspora, and Candida. P. fermentans ITD00165 was the best isoamyl acetate producer, y

7. Atividade antifúngica de óleos essenciais frente à Candida albicans isoladas de pacientes HIV positivos / Antifungal activity of essential oils against Candida albicans isolated from HIV-positive patients.
The use of natural products as potent antimicrobial compound has been studied by Dentistry, especially in combating diseases caused by oral biofilms such as dental caries and oral candidiasis. The aim of this study was to evaluate the antifungal activity of essential oils from Ocimum basilicum L (basil), Cymbopogon martinii Motia (palmarosa), Cyperus articul

8. Comparação genotípica e fenotípica de diferentes isolados clínicos e ambientais de Rhodotorula spp. / Genotypic and phenotypic comparisons among clinical and environmental isolates of Rhodotorula spp.
Introduction: Rhodotorula spp. are yeasts widely distributed in the environment and can colonize the human body at different anatomical locations. This emerging pathogen is capable of causing superficial and invasive infections in humans whereas bloodstream infection is the most commonly described in the literature. Mainly three species have been related to

9. Seleção de leveduras para bioconversão de D-xilose em xilitol / Yeast selection for bioconversion of D-xylose to xilitol
Microbial species, particularly yeast, are of great importance for the production of xylitol. The xylitol production involves complicated metabolic regulation, including the transport of D-xylose, production of key enzymes and cofactor regeneration. Thus, screening of microorganisms that consume D-xylose naturally becomes a viable and effective way to obtain

10. Seleção de leveduras potencialmente produtoras de vitaminas do complexo B e estudo do processo fermentativo visando aplicação em alimentação animal / Screening of potential B-vitamin producer yeasts and the study of fermentation process for feed application
The present work had as the main the objective, the isolation and selection of potential B-vitamin producer yeast and the study of fermentative process for B-vitamin production for feed application. Among 267 isolated strains, one was selected as extracellular thiamine producer and the strain Candida sp. LEB 130 as riboflavin and biotin producer. In the stud

11. Aproveitamento biotecnológico do glicerol derivado da produção de biodiesel para a obtenção de biomassa e ribonucleotídeos / Biotechnological utilization of glycerol derived from biodiesel production for obtaining biomass and ribonucleotides
Este trabalho teve como objetivo a utilização de glicerol, principal subproduto da produção de biodiesel, como fonte de carbono para a produção de biomassa e ribonucleotídeos de leveduras. Com este propósito, foi realizado um screening de leveduras para identificar aquelas cepas com maior capacidade de crescimento em glicerol. As leveduras Hansenula

12. Screening, selection, production and characterization of the enzyme xylanase from wild yeasts / Triagem, seleção, produção e caracterização da enzima xilanase a partir de leveduras silvestres
Endo-1,4-ß-xylanase (E.C. 3.2.1.8), commonly called xylanase, has great application in different types of industries such as feed, food, textiles, paper, ethanol from biomass, among others. These enzymes act in hydrolysis of the xylan, one of the most abundant polysaccharides found in the nature, present in cell plants linked to the hemicelullose. The main
