Publication date: Available online 12 December 2017 Source:Journal of Environmental Chemical Engineering Author(s): Mahwash Mahar Gul, Khuram Shahzad Ahmad Bioremediation of pesticides is imperative for a sustainable environment. For this purpose soil borne, pure fungal strains; Aspergillus niger and Penicillium chrysogenum were augmented in soils spiked with herbicide, Chlorsulfuron from four distinct regions of Pakistan. These strains were found to utilize Chlorsulfuron as their carbon and energy sources. Solid-liquid extraction of pesticide was followed by analysis through high performance liquid chromatography and gas...

Biotransformation of soy flour isoflavones by Aspergillus niger NRRL 3122 β-glucosidase enzyme. Nat Prod Res. 2017 Dec 11;:1-10 Authors: Abdella A, El-Baz AF, Ibrahim IA, Mahrous EE, Yang ST Abstract β-glucosidase enzyme produced from Aspergillus niger NRRL 3122 has been partially purified and characterised. Its molecular weight was 180 KDa. The optimal pH and temperature were 3.98 and 55 °C, respectively. It promoted the hydrolysis of soy flour isoflavone glycosides to their aglycone. Two-level Plackett-Burman design was applied and effective variables for genistein production were...
This study suggests that IgE may play a role in bronchial hyperreactivity associated to A. fumigatus exposure in mice. Mice sensitized and challenged with this fungus showed characteristics of severe asthma, with an increase of BALF neutrophils, histological changes consistent with severe asthma and an increase of IgE capable of triggering type I hypersensitivity.
