Última Biotreatment effects in films and blends of PVC/PCL previously treated with heat 52 Campos,Adriana de; Franchetti,Sandra Mara Martins. Studies were carried out on biomodification and the pre-heat (130(0)C) influence on Poly (vinyl chloride) / Poly (epsilon-caprolactone) films. The results showed that heat pre-treatment improved the biomodification of PVC films, but it inhibited the biomodification of the PVC/PCL film.

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132005000200010 Biodegradation of erythrosin B dye by paramorphic Neurospora crassa 74A 52 Jesus,Gisele Jane de; Corso,Carlos Renato; Campos,Adriana de; Franchetti,Sandra Mara Martins. The present work used paramorphic forms of Neurospora crassa 74A to remove erythrosine. The fungus culture was grown in medium containing the dye, as only carbon source for 2 and 90 h of interaction. A washing process using distilled water isolated the cellular mass mycelia was dried for 12 h at 105ºC and transformed in fine powder and analyzed in FTIR. The supernatant was analyzed through spectrophotometer UV-Vis and FTIR. Significant differences in the spectrum of UV-VIS and FTIR were observed between the control and the supernatant and between wall control and the walls colored by red, in FTIR for 2 and 90 h. Some significant bands were modified, suggesting the possibility of enzymatic biodegradation in proportion to the time of contact between the dye...

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132010000200028 Architecture and relevance of several strongly adhered biofilms over a polyester imide (PEI) surface 58 Soncini-Júnior,Giancarlo; Franchetti,Sandra Mara Martins; Marconato,José Carlos. A microscopical study was undertaken to analyze the eventual fungi adhesion over a polyester imide surface in enameled copper wires. Scanning electron microscopy allowed to observe in these adhered biofilms, a high amount of pigments, hyphae and its enzymatic arsenal probably acting in the surface of the polymer. Due to the highly aromatic nature of this polyester and the residual phenol derivates still present in the reticulated polymer, an antifungal activity could be expected, but no significant changes were noted in fungal growing and in the adhesion process. Additionally, the wires showed completely failure in all insulation properties. The studies aimed to understand and evaluate the great fungi potential that could be explored in biodeterioration...

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822003000500036 Biotransformation of poly (epsilon-caprolactone) and poly (vinyl chloride) blend 58 Campos,Adriana de; Franchetti,Sandra Mara Martins; Agnelli,José Augusto Marcondes. Poly (caprolactone) is a famous biodegradable polymer and miscible with PVC, a commercial synthetic polymer, thermal susceptible and non-biodegradable. This blend is important concerning its mechanical properties and biodegradability. In this work, we testified the biomodification of blend films of PVC/PCL by UV-Vis. spectroscopy. The results show us that there is an interaction between the PVC/PCL film and the microrganisms.
