“…Cinnamodendron dinisii (Canellaceae) is an endemic tree from the Brazilian Atlantic Forest, popularly known as “pimenteira” ( Peixoto and Barros, 2010 ), while Siparuna guianensis (Siparunaceae) is a typical bush of the Brazilian cerrado, popularly known as “negramina”. Decoction of its leaves is traditionally used to relieve fever and body pain ( Valentini et al , 2008 ).…”

This study had analyzed the antibacterial, antifungal and trypanocidal activity of the essential oils from Cinnamodendron dinisii Schwacke (Canellaceae) and Siparuna guianensis Aublet (Siparunaceae). The essential oils were obtained from fresh leaves by hydrodistillation, using a modified Clevenger apparatus. Chemical analysis by gas-liquid chromatography coupled to mass spectrometry (GC-MS) showed that these essential oils are rich in monoterpene and sesquiterpene hydrocarbons. Activity against the pathogenic bacteria Escherichia coli , Listeria monocytogenes , Pseudomonas aeruginosa , Salmonella choleraesuis and Staphylococcus aureus was evaluated with the agar cavity diffusion method, while activity on the filamentous fungi Aspergillus flavus , Aspergillus niger , Aspergillus carbonarius and Penicillium commune was evaluated by the disk diffusion technique. Trypanocidal activity was tested against Trypanosoma cruzi epimastigotes, using the Tetrazolium salt (MTT) colorimetric assay. Both essential oils exhibited low inhibitory effect towards bacteria, showing high MIC values (125–500 μg mL −1 ), with Gram positive bacteria being more susceptible. Better inhibitory effect was obtained for the evaluated fungi, with lower MIC values (7.81–250 μg mL −1 ), being A. flavus the most susceptible species. Both essential oils presented low trypanocidal activity, with IC 50 /24 h values of 209.30 μg mL −1 for S. guianensis and 282.93 μg mL −1 for C. dinisii . Thus, the high values observed for the MIC of evaluated bacteria and for IC 50 /24 h of T. cruzi , suggest that the essential oils have a low inhibitory activity against these microorganisms. In addition, the low MIC values observed for the tested fungi species indicate good inhibitory activity on these microorganisms’s growth.

O rio Cuiabá, pertencente à porção norte do Pantanal mato-grossense apresenta uma ictiofauna rica em diversidade como resultado do ambiente pelo pulso de inundação. Estes ciclos de cheias e secas influenciam as relações sociais, culturais e econômicas da região, em especial a pesca e qualidade de vida das suas comunidades ribeirinhas, que dependem da saúde ambiental do bioma. A criação da Barragem de Manso, principal afluente do rio Cuiabá, influenciou no regime de vazão desse rio e consequentemente na reprodução dos peixes migradores. O objetivo deste trabalho foi refletir a problemática dos pescadores da comunidade ribeirinha de Bonsucesso, Mato Grosso, que sentiu sua vida, ligada à pesca, afetada pela construção da Usina de Manso. Concluiu-se que a descentralização dos recursos hídricos (Lei 9.433/97) precisa ser efetivada na região, já que os pescadores foram prejudicados pela construção da barragem de Manso, pois a mesma linearizou a vazão do rio Cuiabá. Porém, a barragem não é a única culpada pela diminuição do estoque dos recursos pesqueiros dos ribeirinhos.
