2. Characterization of the deposition of collagen fibers and Lithogenic potential in bladder of rats submitted to a sugar cane biopolymer graft
OBJECTIVES: Suture materials are widely used in urology. The interaction of these materials with the extracellular matrix in the inflammatory process can be estimated by stereology of collagen fibers and the present study was designed to determine the behavior of the bladder tissue of rats to grafts of the biopolymer of sugar cane (BPCA), and the inflammatio

3. Estudo da produção de biossurfactante em caldo de fermentação
A bacterium isolated from soil contaminated by hydrocarbon was studied and, by biochemical tests and analysis of PCR, the presence of Bacillus pumilus was identified. The production of biosurfactant was optimized, test of oil degradation and antimicrobial activity determination. The results showed that pH 5.0 and 7.0, 72 h of fermentation, sucrose and sugar

5. AvaliaÃÃo histolÃgica da reaÃÃo tecidual do fio de sutura à base de biopolÃmero de cana-de-aÃÃcar comparado com o adesivo tecidual etil-cianoacrilato e o mononylon 5-0Â: estudo em ratos
Introduction: The suture wires are materials used in the synthesis of surgical wounds or not, and the interaction of the wire with tissues during the cicatricial process, must have among others objectives, the absence of side effects. Objective: analyze by descriptive histologic study the characteristics of the tissue reply between the tissue adhesive ethyl-

8. Membrana de biopolÃmero de cana-de-aÃÃcar como substituto de dura-mÃter em ratos Wistar
Background: Duraplasty is necessary in nearly 30% of all neurological surgeries. Objectives: To determine the utilization of the sugar cane biopolymer membrane patch as a dural substitute in rats. Material and Methods: Forty adults males Wistar rats weighing 300-440g were randomly divided into two groups: a control and an experimental. All animals were anest

9. Desenvolvimento e caracterizaÃÃo de gel de biopolÃmero produzido pela fermentaÃÃo de melaÃo da cana-de-aÃÃcar pelo microorganismo Zoogloea sp. Contendo Ãcido Ãsnico
An exopolysaccharide produced by Zoogloea sp. from sugar cane molasses as a fibrous membrane was used to prepare a gel containing usnic acid, which presents antimicrobial activity. A method of drug extraction from the biopolymer gel was validated. The usnic acid, pure and drug-loaded biopolymer gel were characterized through differential scanning calorimetry

11. Seleção de linhagens produtoras de goma isoladas da cana-de-açucar
The aim of this work was to isolate and select potentia1ly gum producing strains present in sugar cane. Guns are biopolymers carne 1Tom vegetal (e.g., guar gurn, carragen gum) or microbian (e.g., xantan gum, dextran gum) source. Dextran producing bacteria are 1Tequently found in damaged sugar cane. Dextran is a biopolymer that consists of a-Dglucose monomeri

12. Produção e caracterização do biopolimero produzido por Beijerinckia sp isolada do solo cultivado com cana-de-açucar da região de Ribeiro Preto-São Paulo-Brasil
Two microorganisms were isolated and selecionated from a sugar cane plantation from the North-East region of the São Paulo. They were identified as Beijerinckia sp, strains 7070 and 9102AA . Sucrose solutions at concentrations from 0.1 to 5.0% in Yeast Malt medium were used to determine cellular growth of the 7070 strain. The 1 % sucrose medium showed the b
