Development of a consolidated bioprocess for the production of citric acid using Aspergillus niger as biocatalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The industrial production of citric acid, an ingredient in beverages, pharmaceuticals, and cosmetics, is based on microbial fermentation of glucose or sucrose. Given the elevated cost of these sugars, lignocellulosic biomass is emerging as a cost‐effective and environmentally friendly feedstock for sustainable bioprocesses.

Safety evaluation of the food enzyme glucan 1,4-α-glucosidase from the non-genetically modified <i>Aspergillus niger</i> strain AGME 1415. [PDF]

EFSA J
Abstract The food enzyme glucan 1,4‐α‐glucosidase (4‐α‐d‐glucan α‐glucohydrolase; EC 3.2.1.3) is produced with the non‐genetically modified Aspergillus niger strain AGME 1415 by ENMEX SA de CV, a Kerry Company. The food enzyme was considered free from viable cells of the production organism.

Use of Whole Cells and Cell‐Free Extracts of Catalase‐Deficient E. coli for Peroxygenase‐Catalyzed Reactions

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Unspecific peroxygenases (UPOs) and cytochrome P450 monooxygenases (CYPs) with peroxygenase activity are becoming the preferred biocatalysts for oxyfunctionalization reactions. While whole cells (WCs) or cell‐free extracts (CFEs) of Escherichia coli are often preferred for cofactor‐dependent monooxygenase reactions, hydrogen peroxide (H2O2 ...

Insights into the morphology‐productivity relationship of filamentous fungi through small‐scale cultivation and automated microscopy of Thermothelomyces thermophilus

Biotechnology Progress, EarlyView.
Abstract Filamentous fungi are a cornerstone in the biotechnological production of enzymes, proteins, and organic acids. However, challenges in understanding and controlling the relationship between morphology and productivity can limit their application.

Physicochemical Properties Analysis and Secretome of Aspergillus niger in Fermented Rapeseed Meal

PLoS ONE, 2016
The nutrient digestibility and feeding value of rapeseed meal (RSM) for non-ruminant animals is poor due to the presence of anti-nutritional substances such as glucosinolate, phytic acid, crude fiber etc. In the present study, a solid state fermentation (

Evaluation of coffee bean husk fermented by a combination of Aspergillus niger, Trichoderma harzianum, and Saccharomyces cerevisiae as animal feed

Jurnal Ilmu-Ilmu Peternakan, 2022
Abundant coffee bean husk acquires an alternative source of fiber for livestock feed, but a high level of the crude fiber of it became an obstacle. Solid-state fermentation technology using lignocellulolytic fungi is known to be able to improve the ...
