NATURAL OCCURRENCE OF CITRININ AND BIOCONTROL OF ITS PRODUCING FUNGUS BY Trichoderma hamatum IN RICE GRAINS [PDF]

Arab Universities Journal of Agricultural Sciences, 2006
Paddy rice was sampled from El-Sharkia, El-Gharbia, El-Dakahlia and Kafr El-Sheikh governorates, Egypt. Of the 29 samples taken, ten were contaminated with the mycotoxin citrinin. An average of 6.79 x 104 fungal spores per gram rice was found.

Response Surface Modeling for the Enrichment of Gamma-Aminobutyric Acid with a Minimum Content of Citrinin in Monascus-Fermented Rice

eFood, 2019
γ-Aminobutyric Acid (GABA) is a secondary metabolite produced in Monascus-fermented food. The mycotoxin (citrinin), another major secondary metabolite, is neurotoxic to humans and thus it diminishes the social acceptability of Monascus-Fermented Rice ...

Synthesis of Six Natural Products Enabled by Selective Hydroxylation of Orcinaldehyde‐Like Substrates With an Enzyme Library

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Achieving selective (sp3)C–H hydroxylation can streamline the synthesis of complex organic molecules. Biocatalysis presents an opportunity to realize this transformation, however, identifying useful enzymes that enable synthetic strategies can be a challenge due to limitations in enzyme substrate scope.

Efflux at the Blood-Brain Barrier Reduces the Cerebral Exposure to Ochratoxin A, Ochratoxin α, Citrinin and Dihydrocitrinone

Toxins, 2021
Recent studies have implied that environmental toxins, such as mycotoxins, are risk factors for neurodegenerative diseases. To act directly as neurotoxins, mycotoxins need to penetrate or affect the integrity of the blood-brain barrier, which protects ...
