1. Análise da associação bactéria-macroalgas em ambiente marinho e do seu potencial uso na avaliação ambiental.
Nas áreas costeiras um aumento na quantidade de nutrientes, particularmente nitrogênio e fósforo, tem levando à eutrofização com alterações pronunciadas nos ecossistemas. O enriquecimento por nutrientes nos ambientes costeiros é freqüentemente acompanhado pela entrada de poluentes, como os metais pesados. A utilização de macroalgas e de bactéria

2. Autoradiographic Studies of [methyl-3H]Thymidine Incorporation in a Cyanobacterium (Microcystis wesenbergii)-Bacterium Association and in Selected Algae and Bacteria
The present investigation showed by means of autoradiography that the cyanobacterium Microcystis wesenbergii did not incorporate [3H]thymidine at nanomolar concentrations, whereas its associated heterotrophic bacteria appearing in the gelatinous cover of the cyanobacterium became labeled. Several other tested cyaobacteria and algae did not incorporate [3H]th

3. Nature and Role of Bacterial Contaminants in Mass Cultures of Thermophilic Chlorella pyrenoidosa
A study was made of bacterial contaminants isolated from an algal mass-culture unit. The study was performed specifically to determine the dependence of the size of bacterial population on algal density and the nature of any association of the contaminants with the algal cell. Growth of the bacterial contaminants on standard medium was also investigated. An

4. Respiration in Blue-Green Algae
The low rate of endogenous respiration exhibited by the blue-green algae Anacystis nidulans and Phormidium luridum was not increased by the addition of respiratory substrates. However, endogenous respiration was inhibited by low concentrations of cyanide and by high carbon monoxide tensions. In addition, the uncouplers dinitrophenol and carbonyl cyanide p-tr

5. Biofilm Development and Cell Death in the Marine Bacterium Pseudoalteromonas tunicata
The newly described green-pigmented bacterium Pseudoalteromonas tunicata (D2) produces target-specific inhibitory compounds against bacteria, algae, fungi, and invertebrate larvae and is frequently found in association with living surfaces in the marine environment. As part of our studies on the ecology of P. tunicata and its interaction with marine surfaces
