The present work describes the phytochemical prospection and biological activity of the leaves of Curatella americana L., also known as “Caimbé”, belonging to the family Dilleniaceae. The necessary botanical material was obtained in the municipality of Boa Vista, state of Roraima. This species has a wide distribution throughout the intertropical belt, and can be found throughout the belt from Australia to South America. The extract was obtained from dried and pulverized material. The toxic activity against the microcrustacean Artemia salina was then determined.

The purpose of this work was to study the degradation capacity of phenol by strains of Pseudomonas aeruginosa, Acinetobacter sp. and Stenotrophomonas maltophilia isolated from activated sludge from a steel industry. For this, a study of the kinetics of microbial growth and degradation of phenol, besides a factorial planning was carried out, varying the initial concentration of phenol and the pH. Pseudomonas aeruginosa removed 100% of the phenol in 72 h, when the initial concentration of the compound was 250 mg L-1 and the pH was controlled at 6.4. The bacterium Acinetobacter sp.
