The objective of this work was to explore the storage properties of a structured oil-in-water emulsion containing both water- and fat-soluble bioactive compounds from bilberries (Vaccinium myrtillus L.). Bilberry seed oil (BSO) was dispersed in a continuous aqueous phase of anthocyanins (AC) and whey protein isolate. The microstructure was evaluated using light microscopy and the effect of anthocyanins on lipid oxidation and microbial growth was investigated. The results showed that it was possible to generate a stable emulsion structure that resisted phase separation during 25 weeks of storage. Gas chromatography–...

Publication date: Available online 12 August 2018Source: Carbohydrate PolymersAuthor(s): C. Nobre, D.A. Gonçalves, J.A. Teixeira, L.R. RodriguesAbstractAn integrated process enabling the simultaneous production and purification of fructo-oligosaccharides (FOS) was explored. A co-culture fermentation with Aspergillus ibericus (used as FOS producer strain) and Saccharomyces cerevisiae YIL162 W (for small saccharides removal) was optimized. Inoculation conditions of S. cerevisiae, fermentative broth composition, temperature and pH were optimized by experimental design. Yeast extract concentration and temperature...

NgomaAbstractNigeria, being a tropical nation, characterized by favorable climatic conditions, may display high chances of feed contaminations due to aflatoxigenic Aspergillus flavus with the consequences of health risks associated with the consumption of dairy products. A cross-sectional study was conducted to examine the risks of occurrence and distribution of aflatoxigenic Aspergillus flavus (A. flavus) and aflatoxin B1 (AFB1) contamination levels based on the European ...

n RA, Houbraken J Abstract Aflatoxins and ochratoxins are among the most important mycotoxins of all and producers of both types of mycotoxins are present in Aspergillus section Flavi, albeit never in the same species. Some of the most efficient producers of aflatoxins and ochratoxins have not been described yet. Using a polyphasic approach combining phenotype, physiology, sequence and extrolite data, we describe here eight new species in section Flavi. Phylogenetically, section Flavi is split in eight clades and the section currently contains 33 species. Two species only produce aflatoxin B1 and B2 (A. pseud...

This study has demonstrated the potential of xylanases to synthesise AgNPs which is to the best of our knowledge the first record of such. The present study underscores the relevance of xylanases in nanobiotechnology.

Here, the authors describe a simple method to formulate the nanodispersion of hexaconazole (hexa); henceforth, referred to as nanohexaconazole (N-hexa) that is water soluble and effective against several species of Aspergillus. Size and shape of the prepared nanocomposite was determined with high-resolution transmission electron microscopy and field-emission scanning electron microscopy. Nanohexaconazole structure was further confirmed by Fourier-transform infrared spectroscopy and gas chromatography–mass spectrometry. The antifungal efficacy of nanohexaconazole (N-hexa) was studied in vitro, compared with micronised...

AbstractPurpose of ReviewThe incidence of onychomycosis byAspergillus has shown an increase in recent years, representing 34 –60% of onychomycosis due to non-dermatophyte molds. At least 26 species ofAspergillus causing onychomycosis have been reported, some of which may be morphologically indistinguishable but genetically distinct, even in their susceptibility profile to antifungals. So in the diagnosis of this pathology, it is necessary to use both conventional and molecular methods to get to the identification of the fungus at the species level and thus establish the appropriate treatment.Recent FindingsThe curren...

Publication date: Available online 16 August 2018Source: Food ControlAuthor(s): Alireza Sadeghi, Maryam Ebrahimi, Seyed Ali Mortazavi, Abbas AbedfarAbstractIn vitro antifungal activity against Aspergillus niger was used to screen the lactic acid bacteria (LAB) isolated from whole wheat sourdough. Sequencing results of the PCR products led to the identification of Lactobacillus reuteri as the selected isolate. The LAB isolate had a proper anti-aflatoxigenic capability, and it reduced the amount of B1, B2, G1 and G2 aflatoxins, based on the results of HPLC analysis. n-Decanoic acid, 3-hydroxydecanoic acid and 3-hydroxydodeca...

The ratio of initial reaction rates depen...

Publication date: Available online 15 August 2018Source: Microbiological ResearchAuthor(s): Abeer F. ElhagrassyAbstractA total of 35 actinomycetes were isolated from the surface of mural paintings of snu- sort- ankh in El Leasht, Egypt during four seasons all over 2016-2017. In 2009 this tomb was deteriorated by "Aspergillus niger, A. flavus, Fusarium moniliforme, Alternaria alternate, Rhizopus stolonifera, Bacillus subtilis, Bacillus cereus, and micrococcus iuteus." In 2017 the isolation of swabs presents only Aspergillus niger and about 35 actinomycetes classified to three different groups "Streptomyces, N...
