“…Aspergillus niger causes black mold of foodstuffs. Aspergillus oryzae is used to ferment sake, and Aspergillus wentii to process soybeans [8]. Only a few of these molds can cause illness in humans such as Aspergillus flavus, Aspergillus niger, and Aspergillus fumigatus causing aspergillosis.…”

“…Aspergillus species usually interact with organisms in an asymptomatic manner and do not cause illness. However, some species have been shown to be responsible for several disorders in organisms with low immunity that have been massively exposed to fungal spores, such as immunocompromised humans [ 3 , 4 , 5 , 6 , 7 , 8 ], or plants and plant-derived products that have been exposed to mycotoxin-producing molds, leading to food contamination and spoilage [ 9 , 10 , 11 ]. Invasive aspergillosis can be among the most serious fungal infections [ 12 , 13 , 14 , 15 ].…”

The Aspergillus Metabolome Database is a free online resource to perform metabolite annotation in mass spectrometry studies devoted to the genus Aspergillus. The database was created by retrieving and curating information on 2811 compounds present in 601 different species and subspecies of the genus Aspergillus. A total of 1514 scientific journals where these metabolites are mentioned were added as meta-information linked to their respective compounds in the database. A web service to query the database based on m/z (mass/charge ratio) searches was added to CEU Mass Mediator; these queries can be performed over the Aspergillus database only, or they can also include a user-selectable set of other general metabolomic databases. This functionality is offered via web applications and via RESTful services. Furthermore, the complete content of the database has been made available in .csv files and as a MySQL database to facilitate its integration into third-party tools. To the best of our knowledge, this is the first database and the first service specifically devoted to Aspergillus metabolite annotation based on m/z searches.

“…Some of these species, as A. fumigatus, A. flavus or A. ochraceous, are responsible for human and animal diseases, as well as food spoilage. But also some of them, as A. niger and A. oryzae, are widely employed for the production of valuable products that can be used in food industry and health (Sheikh-Ali et al, 2014;Alonso et al, 2015;Reyes et al, 2017;de Vries et al, 2017).…”

Aspergillus flavus is a saprophytic opportunistic plant pathogen that infects crops and stored grains, in a process assisted by the action of enzymes, such as xylanases and pectinases. The enzymatic potential of A. flavus has not been addressed in detail, even when this knowledge could be useful for the understanding of the colonization dynamics during the grains spoilage by fungi, in order to find of strategies to control it. The effect of carbon source and pH on enzyme production was evaluated by growing A. flavus CECT-2687 in liquid cultures on different monosaccharides, polysaccharides or agricultural residues, at several initial pH values. The results showed a significant effect of pH, carbon source and the interaction of both factors. Xylanases were produced on monosaccharides, although the highest xylanolytic activities were obtained on agroindustrial xylan-rich residues. Exopectinases titers were similar on polysaccharides and agricultural residues, and were not observed on monosaccharides. Pectin lyases were produced on pectin and agricultural residues; and a pectin lyase of 27 kDa was identified in crude extracts of lemon peel cultures at initial pH of 8. The highest enzymatic productions were obtained on cultures with initial pH of 8. Keywords: xylanases, exopectinases, pectin lyases, agroindustrial residues, Aspergillus flavus CECT-2687. ResumenAspergillus flavus es saprofito y patógeno oportunista de cultivos y granos almacenados, en un proceso asistido por la acción de enzimas como xilanasas y pectinasas. El potencial enzimático de A. flavus no se ha abordado en detalle, incluso cuando este conocimiento podría ser útil para comprender la dinámica de colonización de granos por hongos y encontrar estrategias para su control. El efecto de la fuente de carbono y el pH sobre la producción de enzimas se evaluó cultivando A. flavus CECT-2687 en cultivos líquidos en diferentes monosacáridos, polisacáridos o residuos agrícolas, a diferentes valores de pH. Se encontró un efecto significativo del pH, la fuente de carbono y su interacción. Las xilanasas se produjeron en monosacáridos, las actividades más elevadas se obtuvieron en residuos agroindustriales ricos en xilano. Los títulos de exopectinasas fueron similares en polisacáridos y residuos agrícolas y no se observaron en monosacáridos. Las pectin liasas se produjeron en pectina y residuos agrícolas; y se identificó una pectina liasa de 27 kDa en extractos crudos de cultivos de cáscara de limón a pH inicial de 8. La mayor producción de todas las enzimas se observó en los cultivos con pH inicial de 8.
