Giancarlo Perrone,Antonia Susca,Giuseppe Cozzi,Kenneth C. Ehrlich,József Varga,Jens Christian Frisvad,M. Meijer,P. Noonim,P. Noonim,Warapa Mahakarnchanakul,Robert A. Samson +10 more
TL;DR: The main recent achievements in the diversity of the aflatoxin gene cluster in A. flavus populations, A. parasiticus and the non-toxigenic A. oryzae are summarized.
Journal ArticleDOI

TL;DR: Using a polyphasic approach combining phenotype, physiology, sequence and extrolite data, eight new species are described in Aspergillus section Flavi, including three newly described species A. aflatoxiformans, A. austwickii and A. cerealis in addition to A. togoensis.
Journal ArticleDOI
Fumonisin B2 production by Aspergillus niger in Thai coffee beans
P. Noonim,Warapa Mahakarnchanakul,Kristian Fog Nielsen,Jens Christian Frisvad,Robert A. Samson +4 more
TL;DR: Liquid chromatography with high-resolution mass spectrometric detection showed that 67% of Aspergillus niger isolates from coffee beans were capable of producing fumonisins B2 (FB2) and B4 when grown on Czapek Yeast Agar with 5% NaCl.
Journal ArticleDOI
Antimicrobial activity of ultrasound-assisted solvent-extracted spices.
TL;DR: The objective of this research was to determine the antimicrobial activity of conventional and high‐intensity ultrasound‐assisted (HI‐US) solvent‐extracted Thai spices, including ginger, fingerroot, and turmeric.
Journal ArticleDOI
Isolation, identification and toxigenic potential of ochratoxin A-producing Aspergillus species from coffee beans grown in two regions of Thailand.
P. Noonim,Warapa Mahakarnchanakul,Kristian Fog Nielsen,Jens Christian Frisvad,Robert A. Samson +4 more
TL;DR: The overall percentage of fungal contamination in coffee was 98% and reduced to 60% after surface disinfection, and the diversity of the fungal population was probably correlated with the geographical origin of the coffee, coffee cultivar, and processing method.
