“…Water can be contaminated by microbiologic agents, including bacteria, viruses, and parasites, even fungi (Hageskal, Lima & Skaar, 2009;Sessegolo et al, 2011). The hydric placement of etiologic agents of infectious character is responsible for the high incidence of diseases that affect the population, this being one of the most frequently referred problems of public health in developing countries.…”

A B S T R A C TBottled water is a product considered safe, although studies already proved fungi incidence even of potential pathogens. The Brazilian legislation does not set limits for this microorganism in water for human consumption, limiting only for bacteria. This study evaluated the fungi contamination in bottled water commercialized in the region of the city of Recife-PE, Brazil. The samples were collected between September and December of 2016. It was used 35 samples from seven companies, different lots, bottled in 500 mL polyethylene terephthalate (PET) bottles and coded from A to G and analyzed to fungi counting by mean of pour plate technique using acidified Potato Dextrose Agar (PDA) at pH 4.0 and incubated to 25°C ± 2°C for up to seven days, accordingly to the Standard Methods for the Examination of Water and Wastewater Methodology. pH data from the samples were obtained by information containing in the labels from the packages. It was observed the fungi presence in 20 samples (57.1%). From the positive samples, there were identified filamentous fungi in 14 (70%), only yeast in 1 (5%), and both in 5 (25%). Packages were considered contamination source. The predominant filamentous fungi in each sample were isolated, purified and submitted to morphological identification at the genus level. The results showed that Aspergillus spp., moreover, Penicillium spp., can be water contaminants. The samples pH, around 5.0, might have contributed for the found fungi maintenance. The filamentous fungi found may be pathogenic or toxigenic, which represents a risk to public health.

Throughout evolution, plants have adapted to different terrestrial habitats and developed the ability to interact with different species of living things, among which, fungi stand out, and have shown great biotechnological or scientific interest and have been isolated and studied from plants in different natural biomes. Thus, the objective was to identify cultivable endophytic fungi associated with Bromeliaceae from the Jurubatiba restinga, state of Rio de Janeiro. Two collections were made in the Restingas de Jurubatiba National Park (PNRJ), located on the north coast of the state of Rio de Janeiro. Samples of healthy plant leaves for the isolation of endophytic fungi were collected from the species of bromeliads inhabiting this restinga: Aechmea nudicaulis (L.) Griseb. (collection 1) and Bromelia antiacantha Bertol (collection 2). Plants were collected at random in order to cover their most representative range. In the laboratory, under conditions aseptic procedures, an isolation procedure for endophytic fungi kept under storage was carried out and, later, identification of isolated fungi, under an optical microscope. The fungal genera were identified: Aspergillus sp., Bipolaris sp., Curvularia sp., Monilia sp., Nigrospora sp., Penicillium sp., Pestalotiopsis sp., And Trichoderma sp. Isolates of Bipolaris sp., Curvularia sp. and Monilia sp. were identified in both collected bromeliads. Within each genus, the isolates were grouped and characterized into subtypes and, based on a bibliographic survey, the endophytic fungi found could be studied for different biotechnological purposes and applicability in different aspects of knowledge, and this was the first report of endophytic fungi. in these species of bromeliads.
