“…In addition, YUSM (yellow unsporulated septate mycelium) and C. cladosporioides presented the highest relative density in CP and CES, respectively. Similar fungal strains were reported by Mallo et al [26] for the city of La Plata in a study related to the presence of airborne fungi detected by various sampling methods. At the same time, Negrin et al [27] reported that Cladosporium sp.…”

Fungal deterioration of building materials causes economic losses due to restoration processes and because it affects the health of the people exposed. Therefore, it is necessary to obtain highly deteriorating fungal strains to carry out studies focused on biodeterioration control. The aim of this research was to study the mycobiota involved in deterioration of facades through the isolation and characterization of fungal strains. In this sense, this paper characterizes the mycobiota that contributes to the deterioration of brick and concrete present in those places. Samples were taken from bricks and concrete with visible biodeterioration of the Cathedral of La Plata and the Experimental Station of the Centro de Investigación y Desarrollo en Tecnología de Pinturas. Relative density, apparition relative frequency, and ecological category of fungi isolates were determined. The deteriorating attributes were determined by carbonate dissolution test, pigment secretion assay, acid production test and brick weight variation. Cladosporium sp., Penicillium sp. and Aspergillus sp. were the taxa with the highest apparition relative frequency and abundance. Aspergillus niger MN371276, Lasiodiplodia theobromae MN371283, Cladosporium sphaerospermum MN371394, Penicillium commune MN371392 and Arthothelium spectabile MT071822 were the strains with the highest biodeteriorant activity. These strains can be used in studies on biodeterioration control of buildings materials.

“…En el aire exterior fueron 22747 esporas m -3 en E1 y 4707 esporas m -3 en E2. Tanto las concentraciones del aire interior como las del exterior fueron superiores a los informes de otras investigaciones realizadas en el Museo de La Plata (Argentina), y en la Galería Nacional de Umbría (Italia), ambas en zonas urbanas, donde se utilizaron, al igual que en este estudio, una metodología volumétrica no viable (Nitiu et al 2016, Mallo et al 2017, Ruga et al 2019. Esto puede deberse a que las condiciones ambientales y la variabilidad de sustratos presente en zonas rurales pueden favorecer mejor el desarrollo de los hongos que en áreas urbanas (Adhikari et al 2004).…”

RESUMEN El estudio de la aeromicobiota de los museos contribuye a la conservación de los materiales que allí se resguardan y a la prevención de enfermedades alérgicas en los visitantes. El objetivo de este trabajo fue determinar la diversidad y calidad fúngica del aire de la Casa Museo Polo Montañez mediante una metodología volumétrica no viable. Se calculó la razón entre las concentraciones fúngicas del aire interior y exterior para evaluar su calidad. Además, se realizó un análisis ecológico de los hongos detectados. La calidad del aire interior de las salas fue buena y se comprobó la similitud entre los taxones del interior y exterior. El tipo esporal Aspergillus/Penicillium destacó por su abundancia en el aire interior y el tipo esporal Cladosporium en el exterior. De la micobiota detectada 12 géneros se informan con propiedades biodeteriorantes y nueve alergénicas. Los cuatro tipos esporales identificados pueden manifestar ambas potencialidades.

“…Two isolation methods were used to recover the cultivable mycobiota associated with the moult of N. granulata inhabiting a brackish salt marsh in Campos del Tuyú National Park (Argentina), which were complementary because they revealed specific taxa. This fact can be closely related to the existence of specific limitations for each isolation method, being physiological requirements (including nutritional ones) the critical aspects such as suggested by Mallo et al (2017). In this sense, the washing technique has been suggested be far more efficient to isolate actively growing microfungi on isolation source (Cabello & Arambarri 2002).…”

This study analysed the mycobiota on exoskeleton debris of the crab Neohelice granulata collected from an alkaline salt marsh and assessed the in vitro enzyme ability of selected isolates at different temperatures and pH. Exoskeleton fragments were incubated in moist chambers on paper and on agar medium. Growth and enzyme ability of selected fungi were also evaluated in agar media with 0.5 % casein, 1% Tween ® 20, and Chitin-Azure ® by the production of a halo/growth ratio. We identifi ed 22 fungal species using both methods. Since the two isolation methods added information to one another, both ones are necessary to recover the cultivable mycobiota associated with the exoskeleton debris. All fungi showed greater levels of enzyme activity in alkaline than acid medium with Tween ® 20. The halo diameter on casein and chitin varied according to the fungal isolate and pH. Most fungi had a larger halo at 4°C than at the other temperatures tested. Clonostachys rosea showed the greatest activity in all media at 4ºC. We conclude that exoskeletons of the N. granulata are a source of fungi able to produce enzyme activities that show differences upon incubation conditions to which they are cultivated such as ones including specifi c temperatures and pH values.
