Cambios en la composición de la comunidad fúngica de biopelículas sobre roca calcárea a través de una cronosecuencia en Campeche, México

Abstract: Antecedentes y Objetivos: La colonización de los sustratos líticos por comunidades fúngicas está determinada por las propiedades del sustrato (bioreceptividad) y las condiciones climáticas y microclimáticas. Sin embargo, los efectos del tiempo de exposición de la superficie de la roca calcárea al ambiente sobre la composición de las comunidades fúngicas no se ha investigado. En este estudio, analizamos la composición y estructura de las comunidades fúngicas inmersas en biopelículas asociadas a roca calcárea, e… Show more

“…The fungal community assemblage considered in this study was previously analyzed in Gómez-Cornelio et al [ 8 ], in which 844 individuals corresponding to 202 species were obtained from biofilm samples on limestone walls with different exposure times [1 year (young biofilm), 5 years (middle-aged biofilm), and 10 years (old biofilm)] to a subtropical climate in Campeche, Mexico. These fungi were isolated by washing and the particle filtration technique.…”

“…This technique reduces the isolation of propagules from spores and favors the isolation of fungi attached to rock particles that likely have an active function on limestone surfaces. From the previously analyzed fungal community [ 8 ], we selected 11 species that were isolated a minimum of seven times and that were distinguishable by their phenotypical characteristics, which included their morphological, growth and reproductive structures ( Table 1 ).…”

“…Fungal species belonging to several of the genera identified in the B communities (e.g. Aureobasidium pullulans, Coniosporium apollinis, Alternaria alternata, Cladosporium, Knufia petricola, and Vermiconia antartica) are reported as RIF and MCF, isolated from patinas on monuments or stone surfaces in urban environments [9,[87][88][89][90][91][92][93][94]. It is well known that these fungi are able to survive the harsh conditions of stone surface due to several adaptations.…”
