INTRODUCTION: Candida albicans being a part of the normal oral microbial flora is one of the most commonly isolated species from the oral cavity. Recent studies have shown a steady rise in the number of non C. albicans species, which are relatively resistant to common antifungal agents and are being recognized as potential pathogens. It is vital to ascertain the predisposing factors leading to such a shift in the oral candidal flora. AIM: To estimate the prevalence of candidal species among vegetarians and non-vegetarians...

For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by hemicellulose hydrolysis could improve de economic viability of this process. Since the Saccharomyces cerevisiae is unable to ferment the pentose, the search for pentose-fermenting microorganisms could be an alternative. In this work, the isolation of yeast strains from decaying vegetal materials, flowers, fruits and insects and their application for assimilation and alcoholic fermentation of xylose were carried out...

REVIEW
J Fortún, F Gioia
There are major differences in the epidemiology and prognosis of invasive candidiasis and candidemia in the neutropenic patient; however, a recent study performed in Spanish hospitals (Candipop) confirmed that mortality at 1 month is 30%, which is similar to that observed in the general population. Although Candida albicans is the most frequently isolated species, C. tropicalis, C. glabrata, and C. krusei are more prevalent than in non-neutropenic patients. The benefit of neutrophil transfusion is unclear, and catheter withdrawal must be tailored and based on confirmation of the diagnosis...

Candida infections vary in severity and manifestation. Common infections include invasive bloodstream infections among hospitalized/immunocompromised patients and vulvovaginal candidiasis among women. Echinocandins and azoles are commonly utilized to treat Candida infections, although echinocandin use has been restricted to indications amenable to once-daily IV administration. CD101, a novel echinocandin with a long plasma half-life and enhanced stability, is in development for once-weekly IV administration for the treatment of candidemia and invasive candidiasis...

Dodecanedioic acid (DDA) is highly useful to the chemical industry as a versatile precursor for producing the polyamide nylon-6,12, which is used for many technical applications, such as heat and chemical-resistant sheaths. However, DDA synthesis has several drawbacks, such as high energy input and cost-intensive removal of by-products. Therefore, alternative bio-based production routes are required due to increasing industrial demand for green chemicals and renewable products. Candida tropicalis converts petrochemical-based n-dodecanes to the corresponding dicarboxylic acids by targeted functionalization...
