AbstractCave tourism represents the main threat for caves and for their conservation. Visitors cause important change in the microclimate and introduce organic carbon and microorganisms into caves. The visitors leave behind skin cells, hair, soil trapped on shoe soles and occasionally vomit, faeces and urine. Recently we faced a new human impact on show caves: chewing gum stuck to the wall. We have found chewing gum on the walls of Cueva del Tesoro, Rincón de la Victoria, Málaga, Spain. The bacteria colonizing the chewing gum were represented by members of Actinobacteria, Alphaproteobacteria and Firmicutes while the fungi were members of the Ascomycota, order Eurotiadles and Hypocreales. From the bacteria, the isolation of Brachybacterirum fresconis, Microbacterium aerolatum, Sphingopyxis italic and Bacillus litoralis wre noteworthy as were the presence of Aspergillus, Fusarium and Penicillium species form the fungi.
