Animal-based medicines: biological prospection and the sustainable use of zootherapeutic resources Anais da ABC (AABC)
Costa-Neto,Eraldo M..
Animals have been used as medicinal resources for the treatment and relieve of a myriad of illnesses and diseases in practically every human culture. Although considered by many as superstition, the pertinence of traditional medicine based on animals cannot be denied since they have been methodically tested by pharmaceutical companies as sources of drugs to the modern medical science. The phenomenon of zootherapy represents a strong evidence of the medicinal use of animal resources. Indeed, drug companies and agribusiness firms have been evaluating animals for decades without paying anything to the countries from where these genetic resources are found. The use of animals' body parts as folk medicines is relevant because it implies additional pressure over...

Antibacterial, antifungal and cytotoxic activities of eight Asteraceae and two Rubiaceae plants from colombian biodiversity BJM
Niño,Jaime; Narváez,Diana M.; Mosquera,Oscar M.; Correa,Yaned M..
Thirty crude extracts of eight plants belonging to Asteraceae and two to Rubiaceae families collected at different places from the Regional Natural Park Ucumarí (RNPU), Colombia, were tested for their antibacterial activity against two Gram-positive and two Gram-negative bacteria and three fungi. Both the antibacterial and the antimycotic activities were tested by the agar well diffusion method. The cytotoxic activity on the same plant extracts was determined through the brine shrimp lethality bioassay. The extracts from the Asteraceae family were more bioactive against Bacillus subtilis and Staphylococcus aureus. The extracts of both families studied were bioactive against the fungi Candida albicans and Fusarium solani. In addition, the extracts of...

BIODISCOVERY AND INTELLECTUAL PROPERTY RIGHTS: A DYNAMIC APPROACH TO ECONOMIC EFFICIENCY AgEcon
Dedeurwaerdere, Tom; Krishna, Vijesh V.; Pascual, Unai.
This paper examines the use the use of economic incentives for knowledge generation through biodiscovery, in the particular case of the use of a highly valuable biogenetic resource stock from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from institutional and ecological economics. Two important conclusions come out of this analysis. First, it highlights the necessity to go beyond standard market approaches to economic valuation in order to address the issues of future possibilities of use and innovation and the integration of the different stages in the process of value creation. Second, it shows the necessity of developing alternatives to the current intellectual...

Bioprospection and characterization of the amylolytic activity by filamentous fungi from Brazilian Atlantic Forest Biota Neotropica
Almeida,Paula Zaghetto de; Pereira,Marita Gimenez; Carvalho,Caio Cesar de; Heinen,Paulo Ricardo; Ziotti,Luciana Sobrani; Messias,Josana Maria; Jorge,João Atilio; Polizeli,Maria de Lourdes Teixeira de Moraes.
Abstract Filamentous fungi are widely diverse and ubiquitous organisms. Such biodiversity is barely known, making room for a great potential still to be discovered, especially in tropical environments - which are favorable to growth and species variety. Filamentous fungi are extensively applied to the production of industrial enzymes, such as the amylases. This class of enzymes acts in the hydrolysis of starch to glucose or maltooligosaccharides. In this work twenty-five filamentous fungi were isolated from samples of decomposing material collected in the Brazilian Atlantic Forest. The two best amylase producers were identified as Aspergillus brasiliensis and Rhizopus oryzae. Both are mesophilic, they grow well in organic nitrogen-rich media produce great...

Bioprospection Beyond Intellectual Property Rights: The Kani Model of Access and Benefit Sharing AgEcon
Pascual, Unai; Dedeurwaerdere, Tom; Krishna, Vijesh V..
This paper addresses the value of bioprospection for genetic resources (GR) and traditional knowledge (TK) from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from evolutionary institutional economics. Drawing on a unique 'access and benefit sharing' (ABS) bioprospecting contract from the Western Ghats, India, we show how the monetary value of plant genetic information from the traditional knowledge holders' perspective can be assessed using a contingent valuation modelling approach. While the study allows the identification of such values from one of the main stakeholder's (i.e, the Kani community) perspective, it also allows to point out some of the key gaps in the...

Cellulolytic potential of a novel strain of Paenibacillus sp. isolated from the armored catfish Parotocinclus maculicauda gut BJM
Castro,André L. M. de; Vollú,Renata E.; Peixoto,Raquel S.; Grigorevski-Lima,André L.; Coelho,Rosalie R. R.; Bon,Elba P. S.; Rosado,Alexandre S.; Seldin,Lucy.
A cellulolytic bacterial strain, designated P118, isolated from the gut of the tropical fish Parotocinclus maculicauda was identified as belonging to the genus Paenibacillus based on phenotypic and chemotaxonomic characteristics and the 16S rRNA gene sequence. The novel strain was Gram-positive, spore-forming and rod-shaped. Catalase but not oxidase was produced. Carboxymethylcellulose was hydrolyzed but starch or gelatin was not. Acetoin production was negative whereas nitrate reduction and urease production were positive. Many carbohydrates served as carbon sources for growth. MK-7 was the predominant isoprenoid quinone. Anteiso-C15:0 (38.73%) and C16:0 (20.85%) were the dominant cellular fatty acids. Strain P118 was closely related to Paenibacillus...

GOMES,ANDREA C.S.M; SANTOS,SAMUEL R. DOS; RIBEIRO,MAYCON C.; CRAVO,PEDRO V.L.; VIEIRA,JOSÉ DANIEL G.; SOUZA,KEILI M.C. DE; AMARAL,ANDRE C..
ABSTRACT In the present work, different Brazilian biomes aiming to identify and select cyclodextrin glycosyltransferase-producer bacteria are explored. This enzyme is responsible for converting starch to cyclodextrin, which are interesting molecules to carry other substances of economic interest applied by textile, pharmaceutical, food, and other industries. Based on the enzymatic index, 12 bacteria were selected and evaluated, considering their capacity to produce the enzyme in culture media containing different starch sources. It was observed that the highest yields were presented by the bacteria when grown in cornstarch. These bacteria were also characterized by sequencing of the 16S rRNA region and were classified as Bacillus, Paenibacillus,...
