Aspergillus niger as a Secondary Metabolite Factory [PDF]
Frontiers in Chemistry, 2021 Aspergillus niger, one of the most common and important fungal species, is ubiquitous in various environments. A. niger isolates possess a large number of cryptic biosynthetic gene clusters (BGCs) and produce various biomolecules as secondary metabolites with a broad spectrum of application fields covering agriculture, food, and pharmaceutical industry.

Polycistronic gene expression in Aspergillus niger
Microbial Cell Factories, 2017 Genome mining approaches predict dozens of biosynthetic gene clusters in each of the filamentous fungal genomes sequenced so far. However, the majority of these gene clusters still remain cryptic because they are not expressed in their natural host. Simultaneous expression of all genes belonging to a biosynthetic pathway in a heterologous host is one ...

Maturation of conidia on conidiophores of Aspergillus niger
Fungal Genetics and Biology, 2017 Conidia of Aspergillus niger are produced on conidiophores. Here, maturation of conidia on these asexual reproductive structures was studied. Pigmented conidia that had developed on conidiophores for 2, 5, and 8days were similarly resistant to heat and were metabolically active as shown by CO2 release and conversion of the metabolic probe Tempone.

Aspergillus niger Spores Are Highly Resistant to Space Radiation
Frontiers in Microbiology, 2020 The filamentous fungus Aspergillus niger is one of the main contaminants of the International Space Station (ISS). It forms highly pigmented, airborne spores that have thick cell walls and low metabolic activity, enabling them to withstand harsh ...

Influence of oxygen concentration on the metabolism of Penicillium chrysogenum
Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract In large‐scale bioreactors, there is often insufficient mixing and as a consequence, cells experience uneven substrate and oxygen levels that influence product formation. In this study, the influence of dissolved oxygen (DO) gradients on the primary and secondary metabolism of a high producing industrial strain of Penicillium chrysogenum was ...

Artificial microbial consortia for bioproduction processes
Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract The application of artificial microbial consortia for biotechnological production processes is an emerging field in research as it offers great potential for the improvement of established as well as the development of novel processes. In this review, we summarize recent highlights in the usage of various microbial consortia for the production
