Characterization of volatile metabolites formed by molds on barley by mass and ion mobility spectrometry

open access: yesJournal of Mass Spectrometry, Volume 55, Issue 5, May 2020., 2020
Abstract The contamination of barley by molds on the field or in storage leads to the spoilage of grain and the production of mycotoxins, which causes major economic losses in malting facilities and breweries. Therefore, on‐site detection of hidden fungus contaminations in grain storages based on the detection of volatile marker compounds is of high ...

Monazite transformation into Ce‐ and La‐containing oxalates by Aspergillus niger

open access: yesEnvironmental Microbiology, Volume 22, Issue 4, Page 1635-1648, April 2020., 2020
Summary Monazite is a naturally occurring lanthanide (Ln) phosphate mineral [Ln x(PO4) y] and is the main industrial source of the rare earth elements (REE), cerium and lanthanum. Endeavours to ensure the security of supply of elements critical to modern technologies view bioprocessing as a promising alternative or adjunct to new methods of element ...

Bioleaching of some Rare Earth Elements from Egyptian Monazite using Aspergillus ficuum and Pseudomonas aeruginosa

open access: yesWalailak Journal of Science and Technology, 2013
Aspergillus ficuum and Pseudomonas aeruginosa exhibit good potential in generating varieties of organic acids effective for bioleaching some rare earth elements (REEs) from Egyptian monazite (purity 97 %) and (thorium-uranium) concentrate.

Utilization of wheat straw for fungal phytase production

open access: yesInternational Journal of Recycling of Organic Waste in Agriculture, 2018
Purpose Wheat straw is an agricultural waste which can be used as a cost effective animal feed. However, high hemicellulose and phytic acid content in wheat straw prevents it as a primary feed choice.

Review on Desirable Microbial Phytases as a Poultry Feed Additive: Their Sources, Production, Enzymatic Evaluation, Market Size, and Regulation

open access: yesInternational Journal of Microbiology, Volume 2024, Issue 1, 2024.
Poultry’s digestive tract lacks hydrolytic phytase enzymes, which results in chelation of dietary minerals, vital amino acids, proteins, and carbohydrates, phytate‐phosphate unavailability, and contamination of the environment due to phosphorus. Therefore, it is necessary to use exogenous microbial phytases as feed additive to chicken feed to catalyze ...

“In Silico” Characterization of 3‐Phytase A and 3‐Phytase B from Aspergillus niger

open access: yesEnzyme Research, Volume 2017, Issue 1, 2017., 2017
Phytases are used for feeding monogastric animals, because they hydrolyze phytic acid generating inorganic phosphate. Aspergillus niger 3‐phytase A (PDB: 3K4Q) and 3‐phytase B (PDB: 1QFX) were characterized using bioinformatic tools. Results showed that both enzymes have highly conserved catalytic pockets, supporting their classification as histidine ...
