Transcriptomics identify the triggering of citrate export as the key event caused by manganese deficiency in Aspergillus niger

Author(s): Fekete E; Bíró V; Márton A; Bakondi-Kovács I; Sándor E; Kovács B; Geoffrion N; Tsang A; Kubicek CP; Karaffa L; ...

For over a century, the filamentous Ascomycete fungus Aspergillus niger has played a pivotal role in the industrial production of citric acid. A critical fermentation parameter that sustains high-y ...

Bioreactor as the root cause of the "manganese effect" during Aspergillus niger citric acid fermentations

Author(s): Fekete E; Bíró V; Márton A; Bakondi-Kovács I; Németh Z; Sándor E; Kovács B; Fábián I; Kubicek CP; Tsang A; Karaffa L; ...

High-yield citric acid production by the filamentous Ascomycete fungus Aspergillus niger requires a combination of extreme nutritional conditions, of which maintaining a low manganese (II) ion conc ...

Effect of Fe2+ ions on gypsum precipitation during bulk crystallization of reverse osmosis concentrates.

Author(s): Melliti E, Touati K, Van der Bruggen B, Elfil H

In reverse osmosis desalination, the concentrate is a saline solution that may become supersaturated. Heterogeneous nucleation of salts occurs at the membrane surface, resulting in the buildup of inorganic deposits on the membrane. The inorganic nucleation ...
