Author(s): Shaimaa Abdelmohsen, Carol Verheecke-Vaessen, Esther Garcia-Cela, Angel MEDINAq, Naresh Magan Penicillium verrucosum is responsible for ochratoxin A (OTA) contamination of temperate cereals during harvesting and storage. Inoculum comes from soil and crop debris. This study examined the effect of temperature (25 vs 30 °C), CO2 (400 vs 1000 ppm) and matric and solute stress (-2.8 vs -7.0...

Author(s): Letícia Harumi Oshiquiri, Suely Lopes Gomes, Raphaela Castro Georg Blastocladiella emersonii is an aquatic fungus of the phylum Blastocladiomycota, localized near the base of the fungal tree. Previous studies have shown that B. emersonii responds to heat shock and cadmium exposure inducing the transcription of a high number of genes, some of them induced by both stresses. A large scale...

Author(s): Laura Haleva, William Lopes, Vanessa Barcellos, Augusto Schrank, Marilene H. Vainstein In nature, microorganisms often exhibit competitive behavior for nutrients and limited space, allowing them to alter the virulence determinants of pathogens. The human pathogenic yeast Cryptococcus neoformans can be found organized in biofilms, a complex community composed of an extracellular matrix...

Author(s): Jerzy Falandysz, Anetta Hanć, Danuta Barałkiewicz, Ji Zhang, Roland TreuAbstractThere is growing evidence that mushrooms (fruiting bodies) can be suitable for biogeochemical prospecting for minerals and as indicators of heavy metal and radioactive contaminants in the terrestrial environment. Apart from the nutritional aspect, knowledge of accumulation dynamics and distribution of...

Author(s): Andrea Tarazona, Eva M. Mateo, José V. Gómez, David Romera, Fernando MateoAbstractThe use of Fusarium-controlling fungicides is necessary to limit crop loss. Little is known about the effect of commercial antifungal formulations at sub-lethal doses, and their interaction with abiotic factors, on Fusarium culmorum and F. proliferatum development and on zearalenone and fumonisin...

Author(s): E. Garcia-Cela, F.J. Gari Sanchez, M. Sulyok, C. Verheecke-Vaessen, A. Medina, R. Kruska, N. MaganAbstractAspergillus flavus is the main xerophylic species in stored peanuts often resulting in contamination with aflatoxins (AFs) and cyclopiazonic acid (CPA). This study evaluated the relationship between storage of shelled peanuts under interacting abiotic conditions on (a) the temporal...

Zhangissina, Tatiana Alikina, Olga N. Yaroslavtseva, Viktor V. GlupovAbstractStrains of entomopathogenic fungi may have substantial differences in their final stages of mycosis. Insect cadavers are usually overgrown with...

Author(s): Rocío Casquete, María José Benito, Emilio Aranda, Alberto Martín, Alejandro Hernández, María de Guía CórdobaAbstractExpression of genes associated with cyclopiazonic acid (CPA) biosynthesis by Penicillium strains in a cheese-based medium has not been previously studied. To control CPA biosynthesis, it would be useful to understand the changes in gene expression during cheese production...

Author(s): Mohamed Hamdi, Hend Bejaoui, Jorge Sá-Morais, Paula RodriguesAbstractOlives and their derivatives, in particular olive oil, represent one of the most significant agricultural products in the Mediterranean basin. Storage under inadequate conditions poses serious problems concerning fungal contamination, with consequent defects and potential mycotoxin production in olives and olive oils...

Author(s): M. Rodríguez-Blanco, A.J. Ramos, V. Sanchis, S. MarínAbstractSilages constitute a major component of the feed ration for dairy cows, being a potential source of mycotoxins due to the possible contamination by filamentous fungi capable of producing these toxic compounds. In this study, samples of different kinds of silages collected from farms located in four regions of Spain, were...

Author(s): Diana Ramírez Albuquerque, Andrea Patriarca, Virginia Fernández PintoAbstractWheat is one of the most important crops in Argentina and worldwide. One of the major diseases affecting the crop is the Fusarium Head Blight (FHB). It is an endemic disease caused mainly by Fusarium graminearum, the most common agent of FHB around the world. The infection is strongly influenced by...
