“…In Mexico City, Penicillium is also the second most common genus 15 . However, in studies performed in other countries, such as France, the USA, Chile and Cuba, Cladosporium has stood out as the most prevalent genus [16][17][18] .…”

introduction:This study aimed to identify airborne fungi in São Luis, Maranhão, Brazil, to determine the prevalent genera and to correlate these genera with the area and season. Methods: In total, 1,510 colony-forming units (CFUs) of airborne fungi were isolated from the north, south, east and west sides and from the center of the city from January to December 2007. The samples were collected on Petri dishes that were exposed to the fungi by the gravitational method. Results: Twenty genera of fungi were isolated; the most common were Aspergillus (33.5%), Penicillium (18.8%), Cladosporium (14.2%), Curvularia (10.6%) and Fusarium (7.6%). The CFUs of the fungi were statistically signifi cant (p < 0.0001). Fungal biological diversity was present all year, without any large seasonal variations but with slight increases in May, August and September. Conclusions: The fungal genera identifi ed in this study were correlated with natural systems and could be useful when evaluating the impact of environmental changes on the region.

“…The survey of airborne fungi spores by variable means has been done (LUO et al, 2007;OLIVEIRA et al, 2009a;KUDO et al, 2011;DAS;GUPTA-BHATTACHARYA, 2012;ALMAGUER et al, 2013;RIEUX et al, 2014;AHER et al, 2015). The assessment of air inoculum can contribute to understanding the potential risk of epidemics of diseases during the plant cycle (WAKEHAM; KENNEDY, 2010;KIMBER 2015;IGARASHI et al, 2016).…”

“…In some places, qualitative studies are made, and the most common airborne fungi spore assessed are anamorphic fungi and a much smaller amount are Uredinales-like spore (AHER et al, 2015). Other studies, beyond qualitative evaluations, make quantitative monthly assessments, and, sometimes, hourly collected spore quantifications (OLIVEIRA et al, 2009b;ALMAGUER et al, 2013). The highest concentrations of daily collected spores are around 9:00 am and 7:00 pm (GRANKE et al, 2014;ALMAGUER et al, 2013;FALL et al, 2016).…”

The Asian rust (Phakopsora pachyrhizi) is one of the most destructive diseases of soybean in Brazil. Despite its importance, little is known about the airborne inoculum production dynamics of pathogen throughout the soybean cycle in Brazil. The objective of this study was to assess the temporal variation of air collected P. pachyrhizi urediniospores using a Burkard 7-day-spore-trap during 2006-2007 and 2007-2008, from November to March of each soybean (MSoy-8001) growing season. The disease severity was quantified on soybean planted in

A new miniaturized sensor system with an internal optical reference for the detection of mold growth is presented. The sensor chip comprises a reaction chamber provided with a culture medium that promotes the growth of mold species from mold spores. The mold detection is performed by measuring impedance changes with integrated electrodes fabricated inside the reaction chamber. The impedance change in the culture medium is caused by shifts in the pH (i.e., from 5.5 to 8) as the mold grows. In order to determine the absolute pH value without the need for calibration, a methyl red indicator dye has been added to the culture medium. It changes the color of the medium as the pH passes specific values. This colorimetric principle now acts as a reference measurement. It also allows the sensitivity of the impedance sensor to be established in terms of impedance change per pH unit. Major mold species that are involved in the contamination of food, paper and indoor environments, like Fusarium oxysporum, Fusarium incarnatum, Eurotium amstelodami, Aspergillus penicillioides and Aspergillus restrictus, have been successfully analyzed on-chip.
