2. Reviewing Microbial Behaviors in Ecosystems Leading to a Natural Quorum Quenching Occurrence
ABSTRACT Quorum sensing is considered one of the most important discoveries in cell-to-cell communication. Although revealed in Bacteria, it has been identified as well as a mechanism present in the other two domains, Eukaryota and Archaea. This phenomenon consists mainly of an exchange and sensing of "words" produced by each cell: chemical signals known as

4. Bioprospecting for bioactives from seaweeds: potential, obstacles and alternatives
Seaweeds are potential sources of high biotechnological interest due to production of a great diversity of compounds exhibiting a broad spectrum of biological activities. On the other hand, there is an urgent need for management options for a sustainable approach to the use of marine organisms as a source of bioactive compounds. This review discusses the bio

5. Rhodolith beds in Brazil: a new potential habitat for marine bioprospection
Rhodoliths are the free-living forms of a number of nongeniculate coralline algae. Rhodolith beds are a common feature of subtidal environments and have been recognized as important carbonate producers and paleoenvironmental indicators, as well as recognized as habitat-forming species. The rhodolith structure provides a hard three-dimensional substrate servi

6. Comparative analysis of the corps en cerise in several species of Laurencia (Ceramiales, Rhodophyta) from the Atlantic Ocean
Different species of Laurencia have proven to be a rich source of natural products yielding interesting bioactive halogenated secondary metabolites, such as terpenoids and acetogenins. It is shown that such compounds are accumulated in the spherical, reniform to claviform refractive inclusions called corps en cerise (CC), which are intensively osmiophilic an

7. Alelopatia e bioprospecção em Rapanea ferruginea e Rapanea umbellata
Allelopathy is a process that involves primary or secondary metabolites produced by plants and microorganisms, which influences the growth and development of agricultural and biological systems. The intensity of plant allelopathic effects may depend on the hábitat, age and the biotic and abiotic conditions during the seasons in which they were collected. Wh

8. Estudo Químico e Bioprospecção de Produtos da abelha Apis mellifera L. do Estado do Ceará / Study Chemical Products and Bioprospecting bee Apis mellifera L. Ceará State
Ceará is one of the largest producer and exporter of Apis mellifera L. honey in Brazil but there is little information about its physical and chemical properties and biological activities. The main aim of this thesis is the chemical study and bioprospection of honeys, propolis and pollen produced by Apis mellifera L. in Ceará State, as manner of to obtain

9. New PHA products using unrelated carbon sources
Polyhydroxyalkanoates (PHA) are natural polyesters stored by a wide range of bacteria as carbon source reserve. Due to its chemical characteristics and biodegradability PHA can be used in chemical, medical and pharmaceutical industry for many human purposes. Over the past years, few Burkholderia species have become known for production of PHA. Aside from tha

10. Bioprospection of yeasts as biocontrol agents against phytopathogenic molds
Yeasts isolated from sugar cane and maize rhizosphere, leaves and stalks were screened against the phytopathogenic molds Colletotrichum sublineolum and Colletotrichum graminicola, both causal agents of the anthracnose disease in sorghum and maize, respectively. Strains identified as Torulaspora globosa and Candida intermedia were able to inhibit the mold gro

11. Bioprospecção de genes envolvidos na síntese de biossurfactantes a apartir de microbiota de resevatórios de petróleo / Bioprospection of genes involved in the synthesis of biosurfactants from braziliam petroleum reservoirs microbial communities
Bioemulsifiers or biosurfactants are compounds produced by microorganisms which enhance the bioavailability of hydrophobic substances promoting the stabilization of substances with different polarities, like oil-in-water emulsion occurring in petroleum reservoirs. The samples used in this work were collected in the Potiguar Basin (RN, Brazil), and employed a

12. Bioprospecção de Actinobactérias da rizosfera de milho ( Zea mays L.) com atividade antifúngica / Bioprospection of actinobacteria from maize (Zea mays L.) rhizosphere with antifungal activity.
Actinobacteria occur in different environments and have a great potential in producing enzymes, antibiotics and medical molecules. The present work aimed the isolation, identification and the bioprospection by rhizosphere actinobactérias. Sixty strains were isolated from healthy plants of maize, cultivated in different regions Socorro, Serra Negra and Ribei
