Oxygen Consumption in Filamentous Pellets of Aspergillus niger: Microelectrode Measurements and Modeling

Biotechnology and Bioengineering, Volume 122, Issue 2, Page 306-321, February 2025.
We isolated pellets from Aspergillus niger cultivations and measured local oxygen concentrations using a microelectrode. These identical pellets underwent structural analysis via microcomputed tomography to produce 3D images. By integrating data from both methods, we analyzed hyphal oxygen supply and developed a model to simulate oxygen concentration ...

Investigating the Phylogenetic Range of Gibberellin Biosynthesis in Bacteria

Molecular Plant-Microbe Interactions, 2017
Certain plant-associated microbes can produce gibberellin (GA) phytohormones, as first described for the rice fungal pathogen Gibberella fujikuroi and, more recently, for bacteria, including several rhizobia and the rice bacterial pathogen Xanthomonas ...

Gibberellic Acid (GA3): A Versatile Chiral Building Block for Syntheses of Pharmaceutical Agents

Chemistry &Biodiversity, Volume 22, Issue 1, January 2025.
Abstract Gibberellic acid (GA3), an ent‐kaurene tetracyclic diterpene, has been considered to be a chiral pool for the chemical transformation of significant heterocyclic compounds. This chiral pool continues to influence modern synthetic chemistry as an inexpensive and versatile starting material since it is widely applied in agriculture.

Growth regulating metabolites: Gibberellin compounds derived from rice disease-producing fungus exhibit powerful plant growth regulating properties

California Agriculture, 1956
The gibberellins, chemical compounds exhibiting a variety of remarkable growth regulating properties, are metabolites—products of metabolism—of Gibberella fujikuroi, a fungus which causes a disease of rice characterized by pronounced stem elongation and,

Production of ent-kaurene from lignocellulosic hydrolysate in Rhodosporidium toruloides

Microbial Cell Factories, 2020
Background Rhodosporidium toruloides has emerged as a promising host for the production of bioproducts from lignocellulose, in part due to its ability to grow on lignocellulosic feedstocks, tolerate growth inhibitors, and co-utilize sugars and lignin ...
