9. DISINFECTION PROTOCOL AND IN VITRO GERMINATION OF SEEDS OF Dalbergia nigra
ABSTRACT The Atlantic Forest is a biome that has suffered anthropic actions, such as the extraction of hardwood, which can lead to the extinction of endemic species of great economic and ecological value, such as Dalbergia nigra. In this perspective, large-scale multiplication studies are necessary to contribute to the conservation of this species. The objec

10. Atomic force microscopy evidences of bacterial cell damage caused by propolis extracts on E. coli and S. aureus
Abstract The interaction of the aqueous extract of green propolis with the bacterial envelope was investigated using atomic force microscopy on E. coli and S. aureus, as Gram-negative and Gram-positive model microorganisms. The bacteria were incubated in the extracts with variable proportions of water/ethanol, i.e., in different concentrations of total pheno
