1. Protección antiincrustante de estructuras sumergidas mediante recubrimientos formulados con 7-hidroxi-4-metilcumarina
ABSTRACT Biofouling settlement on submerged structures such as ships, buoys, farms, off-shore platforms and meteorological stations induces economic losses as a consequence of material deterioration and withdraw from service. Environmental regulations focus on the use of environmental friendly products to replace metallic biocides included in antifouling pai

2. Efecto inhibidor del dióxido de germanio sobre el biofouling del puerto de Mar del Plata
ABSTRACT Marine biofouling on any new material immersed in seawater can lead to extra costs due to increased maintenance, or/and even mechanical wear, and/or biodeterioration that require costly antifouling measures. Fouling organisms growing on immersed manmade surfaces affect hulls, piers, buoys, aquaculture and pipes mainly. Following adsorption of a cond

3. TiO2 thin Films for Biofouling Applications
This work presents a study of TiO2 thin films prepared by sputtering, for using as protection for biofouling action on marine structures. Titanium oxide thin films were prepared with different amount of oxygen on the surface of regular 1020 steel, a structural material for marine technology. The cristalline structure analysis evidenced the formation of anata

4. Laser Surface Modification of Ti6Al4V-Cu for Improved Microhardness and Wear Resistance Properties
To modify the properties of Ti6Al4V alloy, Cu has been added to host an antimicrobial effect in the revised alloy for marine application. The Laser Metal Deposition (LMD) process on the Ti6Al4V alloy and Cu was been investigated for surface modification in order to combat the problem of biofouling in the marine industry. The investigations focused on the mic

6. Macrofauna séssil e sedentária do Naufrágio Pirapama, Pernambuco, Brasil
Naufrágios são classificados como ambientes recifais artificiais, estruturas imersas em ecossistemas aquáticos (principalmente marinhos) que fornecem abrigo, substratos consolidados, áreas de crescimento, alimentação e de berçário. Este estudo objetivou pesquisar a biodiversidade bentônica animal do Naufrágio Pirapama, localizado a 23 m de profundi

7. 2(5H)-Furanone: a prospective strategy for biofouling-control in membrane biofilm bacteria by quorum sensing inhibition
Biofouling of membranes demands costly periodic cleaning and membrane replacement. A sustainable and environmentally friendly solution for maintenance is not available and would be of great interest for many purposes including economical. As complex biofilm formation by environmental strains is the major cause of biofouling and biofilm formation in most case

8. Biofouling e biodeterioração química de argamassa de cimento portland em reservatório de usina hidroelétrica
Last decade Brazilian rivers experimented progressive biofouling of Limnoperna fortunei communities and Cordylophora caspia hydroids. The microhabitat is so favorable that in around 1.5 years L. fortunei increased from 0.39 to nearby 149,000 units/m². Ten Portland cement mortar samples were produced with 1: 3.5: 0.4 dosages and installed for 1 year at Salto

9. Development, validation and application of molecular method based on extraction, amplification and sequencing of the rRNA for the identification of biofilm-forming bacteria on the surface of the reverse osmosis membranes. / Desenvolvimento, validação e aplicação de método molecular baseado na análise do rRNA para a identificação das bactérias formadoras de biofilme metabolicamente ativas na superfície das membranas de osmose reversa.
A method based on extraction of rRNA, followed by RT-PCR of 16S rRNA, cloning and ARDRA was optimized and validated for identification of bacteria active in biofilms. The method was first tested with artificial three-membered consortia. Cloning and RT did not lead to significant changes in the composition of the artificial consortia, but a reduction in cycle

10. Development and characterization of Cottage-like Cheese additioned of Lactobacillus delbrueckii UFV H2b20 and inulin / Desenvolvimento e caracterização de queijo tipo Cottage adicionado de Lactobacillus delbrueckii UFV H2b20 e de inulina
Probiotics are microorganisms which promote beneficial effects on the health of their host when ingested with food in adequate quantities. Prebiotics, on the other hand, are indigestible ingredients which selectively stimulate the growth or the metabolic activity of beneficial bacteria in the colon. A product is called symbiotic when it contains probiotic ce

11. Estudo da influência das monocloraminas sobre as membranas de poliamida da osmose inversa
A tecnologia de separação por membranas, especialmente a osmose inversa, está sendo usada atualmente como uma alternativa de produção de águas com maior qualidade e, também, como processo de tratamento de águas industriais para reuso. Entretanto, a utilização das membranas é limitada pela sua vida útil e varia conforme a natureza e quantidade de

12. Estudo qualitativo da sucessÃo ecolÃgica, recrutamento e do tratamento "anti-fouling" convencional em organismos incrustantes, na regiÃo portuÃria de Suape-Pernambuco, Brasil
The "fouling", process of adhesion, settling and development of beings livings on living and not living materials on a submerged substratum, can be harmful when it is established on structures constructed for the man. The knowledge of the biological and ecological processes in the fouling community, shows particular elements in accordance with the geographic
