Conidia survival of Aspergillus section Nigri, Flavi and Circumdati under UV-A and UV-B radiation with cycling temperature/light regime
García Cela, Esther; Marín Sillué, Sònia; Reyes, Mónica; Sanchís Almenar, Vicente; Ramos Girona, Antonio J. (Wiley, 2016)Bio-geographical differences in fungal infection distribution have been observed around the world, confirming that the climatic conditions are decisive in colonization. This research is focused on the impact of ultraviolet ... -
Ecophysiological characterization of Aspergillus carbonarius, Aspergillus tubingensis and Aspergillus niger isolated from grapes in Spanish vineyards
García Cela, Esther; Crespo Sempere, Ana; Ramos Girona, Antonio J.; Sanchís Almenar, Vicente; Marín Sillué, Sònia (Elsevier, 2014-03-03)The aim of this study was to evaluate the diversity of black aspergilli isolated from berries from different agroclimatic regions of Spain. Growth characterization (in terms of temperature and water activity requirements) ... -
Effect of preharvest anti-fungal compounds on Aspergillus steynii and A. carbonarius under fluctuating and extreme environmental conditions
García Cela, Esther; Gil-Serna, J.; Marín Sillué, Sònia; Acevedo, H.; Patiño, B.; Ramos Girona, Antonio J. (Elsevier, 2012)Ochratoxin A (OTA) has been found in pre-harvest and freshly harvested wheat. Spanish climatic conditions point to Aspergillus species as probably responsible for this OTA. In this study the effectiveness of 5 non-specific ... -
Effect of ultraviolet radiation A and B on growth and mycotoxin production by Aspergillus carbonarius and Aspergillus parasiticus in grape and pistachio media
García Cela, Esther; Marín Sillué, Sònia; Sanchís Almenar, Vicente; Crespo Sempere, Ana; Ramos Girona, Antonio J. (Elsevier, 2015-01)The effects of two exposure times per day (6 and 16 h) of UV-A or UV-B radiation, combined with dark and dark plus light incubation periods during 7e21 d on fungal growth and mycotoxins production of Aspergillus species ... -
Emerging risk management metrics in food safety: FSO, PO. How do they apply to the mycotoxin hazard?
García Cela, Esther; Ramos Girona, Antonio J.; Sanchís Almenar, Vicente; Marín Sillué, Sònia (Elsevier, 2012)This review focuses on risk management issues applied to mycotoxins and, in particular, the Codex Alimentarius recommendations for microbiological hazards are considered. Mycotoxins are chemical hazards from microbiological ... -
Mould growth and mycotoxin production as affected by Equisetum arvense and Stevia rebaudiana extracts
García, Daiana; García Cela, Esther; Ramos Girona, Antonio J.; Sanchís Almenar, Vicente; Marín Sillué, Sònia (Elsevier, 2011)Cereals are very important for human and animal diet. However, agricultural products can be contaminated by moulds and their mycotoxins. On the other hand, natural plant products with antimicrobial properties could be a ... -
Ochratoxigenic moulds and effectiveness of grape field antifungals in a climatic change scenario
García Cela, Esther; Ramos Girona, Antonio J.; Sanchís Almenar, Vicente; Marín Sillué, Sònia (Wiley, 2012)BACKGROUND: The presence of ochratoxin A (OTA) in grapes and grape derivatives has been reported mainly in the Mediterranean area. Consequently, great efforts are being made to prevent the growth of Aspergillus on grapes. ... -
Risk management towards food safety objective achievement regarding to mycotoxins in pistachio: the sampling and measurement uncertainty issue
García Cela, Esther; Ramos Girona, Antonio J.; Sanchís Almenar, Vicente; Marín Sillué, Sònia (Elsevier, 2013)The emerging risk management metrics, FSO, PO and PC, were applied to the aflatoxins (AFs) and ochratoxin A (OTA) determination in 8 commercial lots of pistachio. In order to determine the sampling uncertainty, two sampling ...
