Presence of aspergillus and other fungal symbionts in coffee beans from colombia

Fungi are common inhabitants of plants and plant-derived products. Some of these fungal species are potentially dangerous to human health since they are able to produce chemical substances that alter normal physiological activity. There are no studies about natural mycoflora associated with coffee b...

description Fungi are common inhabitants of plants and plant-derived products. Some of these fungal species are potentially dangerous to human health since they are able to produce chemical substances that alter normal physiological activity. There are no studies about natural mycoflora associated with coffee beans in Colombia, and nothing is known about the presence and abundance of toxigenic fungal species in Colombian coffee. In this study 5,000 coffee beans were studied by plating them on potato-based artificial culture medium and it was shown that potentially toxigenic fungal taxa (mostly from genera Aspergillus, Fusarium, Penicillium), are currently found in Colombian coffee beans. This is true for all steps of coffee processing, from berries in trees to toasted grains, including packed coffee ready for retail in supermarkets. Results show that the distribution of these fungi is not random among different steps of coffee processing, which means that some steps are more vulnerable to infection with some fungi that others. The convenience of establishing a program devoted to detect fungi and/or mycotoxins in Colombian commodities, specially coffee, is discussed here.

Algunos de tales hongos son potencialmente peligrosos para la salud porque producen compuestos químicos fisiológicamente activos, como alcaloides y toxinas. En Colombia no hay estudios sobre la micoflora naturalmente asociada a granos de café, ni sobre la presencia de especies toxígenas en dicho producto. En este estudio se tomaron muestras de 5.000 granos de café en diferentes estadios de su procesamiento, encontrando que taxones fúngicos potencialmente toxígenos, tales como Aspergillus, Fusarium y Penicillium, son comúnmente encontrados en todos los estadios del procesamiento de café. El estudio incluyó muestras desde el fruto en el árbol hasta café tostado y empacado listo para la venta en supermercados. Los resultados muestran que la distribución de estos hongos no es al azar entre los diferentes pasos en el procesamiento del café, lo que significa que algunos pasos son más vulnerables a la infección con hongos que otros. Se discute la conveniencia de establecer un programa dedicado a la detección de hongos o micotoxinas en Colombia y las implicaciones de esto en la salud pública.application/pdfspaUniversidad Nacional de Colombia, Facultad de Ciencias, Departamento de Biolog�ahttp://revistas.unal.edu.co/index.php/actabiol/article/view/14691Universidad Nacional de Colombia Revistas electrónicas UN Acta Biológica ColombianaActa Biológica ColombianaGamboa-Gaitán, Miguel Ángel (2012) Presence of aspergillus and other fungal symbionts in coffee beans from colombia.
