Biotechnological potential of the Carapa guianensis, Bertholletia excelsa and Copaifera spp. oils.

The use of vegetable species for treatment or prevention of diseases is one of the most ancient medicine techniques in humanity. In Amazon rainforest, there are numerous of plant species that possess biotechnological potential, and due to this, this study aimed at carrying out a bibliographic review describing the biotechnological potential in Carapa guianensis, Bertholletia excels, and Copaifera spp. oils. This study is a systematic review of literature in the databases: SCIELO, VHL and PUBMED, by using the descriptors: C. guianensis oil, B. excelsa oil and Copaifera spp. After the selection, 87 articles were selected; 48 on C. guianensis, 9 on B. excels, and 30 on Copaifera spp. Oil seeds from Amazon rainforest possess a good biotechnological potential to be explored. This review has shown that C. guianensis and Copaifera spp. are strong candidates for the search of new insecticide, antiparasitict, anti-inflammatory and healing products. Copaifera spp. has also shown to be promising for the production of antibiotic and antifungic medicines, and C. guianensis for acaricide drugs. Future studies are indicated to deepen the knowledge already described and to investigate new biotechnological potentialities of Amazonian oil seeds. However, for this to happen, greater financial support is required from the Brazilian government and agencies, thus increasing the level of research in the region, which will consequently maximize the likelihood of new product discovery

Analysis of fungal microbiota of ambient air in an intensive care unit in Rio Branco, Acre, Western Amazon, Brazil

Abstract Fungi exhibit three adverse effects on human health: inflammatory, allergic and toxic effects, these implications affect mainly immunodepressed patients. The objective of this work was to analyze the fungal microbiota of the ambient air of an Intensive Care Unit. Three collections were carried out in an Intensive Care Unit in the city of Rio Branco, Acre, Western Amazon, Brazil from March to May 2017. 126 Petri dishes were exposed with the culture medium Agar Sabouraud with chloramphenicol and Agar Mycosel, considering the distribution of the 21 air conditioners, split residential model. The plates were incubated for seven days at room temperature and the growth of Colony Forming Units was observed. Colony counting and isolation for the morphological characterization of the granted fungi was performed. After quantification, the concentration of fungi per cubic meters of air (CFU.m-3) was settled. The third collection had a larger number of colony forming units with 48.6%. In the total of the analyzed samples, filamentous fungi (85.5%) and yeasts (14.5%) were isolated. Thirteen genera of fungi were identified, with the most frequent filaments being Cladosporium spp. 33.0%, Aspergillus spp. 30.4% and Penicillium spp. 19.6%, and yeasts Candida spp. 52.6%, Trichosporon spp. 36.9%. The colony-forming unit per cubic meter (CFU.m-3) did not shown any difference between the Cores in the same collection period, however in the 1st and 3rd collection, Core 1 had the highest average. The fungal microbiota of this Unit presented thirteen different genera potentially pathogenic, revealing the need for monitoring microorganisms and prevention actions
