In an attempt to isolate Paracoccidioides brasiliensis from nature 887 samples of soil from Botucatu, SP, Brazil, were collected cultured in brain heart infusion agar supplemented with dextrose, in potato dextrose agar and in yeast extract starch dextrose agar, all with antibiotics, at 25 degrees and 37 degrees C. Five thermo-dependent dimorphic fungi morphologically resembling P. brasiliensis ...

In this present work, a kinetic model for biosorption of copper was developed considering the possibility of different forms of functional groups being present on the surface of the biomass prepared from Aspergillus niger. Results showed that metal uptake by A. niger was a mass transfer driven process, requiring only 30min to achieve 70% adsorption efficiency. Copper sorption by A. niger was in...

The presteady-state kinetic parameters of the interaction ofwild-type glucoamylase from Aspergillus niger (EC 3.2.1.3)with maltose were obtained and analysed in the pH range 3-7 withintervals of 0.25 pH units. In all cases the following three-step reaction scheme was found to apply. [Equation: see text]. The general result of the analysis of the presteady-state kinetics is that glucoamylase G1 ...

The electrostatic surface potential of fungal spores is generally regarded as potentially influencing spore aggregation and pellet formation in submerged cultures of filamentous fungi. Spores of Aspergillus niger are typically characterized by negative zeta potentials over a wide range of pH values. In this study, this particular behavior is ascribed to the presence of an extensive melanin coat...

Endosulfan is a chlorinated pesticide; its persistence in the environment and toxic effects on biota are demanding its removal. This study aims at improving the tolerance of the previously isolated fungus Aspergillus niger (A. niger) ARIFCC 1053 to endosulfan. Released chloride, dehalogenase activity, and released proteins were estimated along with analysis of endosulfan degradation and pathway...

The aim of this study was to determine the incidence of Aspergillus infections among the patients attending at tertiary care hospital and Hospital environment in Navi Mumbai, India, from January 2014 to December 2014. Total 1785 samples were included in this study for prevalence of Aspergillus species. Out of which 251(14.06%) were positive for Aspergillus infection. Species wise distribution o...

This paper reports a solid-state fungal fermentation-based pre-treatment strategy to convert wheat straw into a fermentable hydrolysate. Aspergillus niger was firstly cultured on wheat straw for production of cellulolytic enzymes and then the wheat straw was hydrolyzed by the enzyme solution into a fermentable hydrolysate. The optimum moisture content and three wheat straw modification methods ...

We investigated the in vitro interaction of terbinafine with itraconazole, fluconazole, amphotericin B and 5-flucytosine, against Aspergillus spp. We tested three isolates of Aspergillus fumigatus (one resistant to itraconazole), and two each of Aspergillus flavus, Aspergillus niger and Aspergillus terreus. We employed a broth microdilution-based method derived from an in vivo validated method ...

OBJECTIVES Hevea brasiliensis extract could potentially be employed as a relatively low cost resource for various anti-fungal activities due to the simplicity of latex preparation and the abundance of latex that can be obtained in rubber producing regions. The present study was aimed at examining the species specific anti-fungal property of H. brasilensis latex C-serum against Aspergillus niger...

In the southeast Asia region, particularly Indonesia, Thailand, Malaysia, brasiliensis Muell. Arg.) has been widely used as a raw material in various industries furniture manufacturing. However, is highly susceptibl...
