José D. Fontana,A. M. De Souza,C. K. Fontana,I. L. Torriani,J. C. Moreschi,B. J. Gallotti,S. J. De Souza,G. P. Narcisco,J. A. Bichara,L. F. X. Farah +9 more
TL;DR: Once applied on exudating or bloody tissues, this biofilm displays several advantages as a biological dressing, and hence, it is valuable as a temporary skin substitute in the treatment of skin wounds, such as burns, ulcers, grafts, and as an adjuvant in dermal abrasions.
Journal ArticleDOI
Recent developments in microbial inulinases. Its production, properties, and industrial applications.
Ashok Pandey,Ashok Pandey,Carlos Ricardo Soccol,P. Selvakumar,Vanete Thomaz Soccol,Nadia Krieger,José D. Fontana +6 more
TL;DR: More recent developments, especially those made in the past decade, on microbial inulinases—its production using various microorganisms and substrates are reviewed.
Journal ArticleDOI
Larvicidal action of ethanolic extracts from fruit endocarps of Melia azedarach and Azadirachta indica against the dengue mosquito Aedes aegypti
Carolina Bueno Wandscheer,Jonny E. Duque,Mario Antonio Navarro da Silva,Yoshiyasu Fukuyama,Jonathan L. Wohlke,Juliana Adelmann,José D. Fontana +6 more
TL;DR: The findings seem very promising, suggesting that it may be possible to increase the larvicidal activity further by improving the extraction and the fractionation of the crude limonoids, for instance removing the co-extracted natural fats.
Journal ArticleDOI
Sweet diterpenic glycosides balance of a new cultivar of Stevia rebaudiana (Bert.) Bertoni: Isolation and quantitative distribution by chromatographic, spectroscopic, and electrophoretic methods
Antonio Sérgio Dacome,Cleuza C. da Silva,Cecília Edna Mareze da Costa,José D. Fontana,Juliana Adelmann,Silvio Claudio da Costa +5 more
TL;DR: In this article, a dichloromethane fraction and a ultrafiltered water extract of leaves of a new cultivar of Stevia rebaudiana were submitted to separated downstreaming fractionation in silica gel columns.
Journal Article
Effect of Nitrogen and Carbon Sources on Lipase Production by Penicillium aurantiogriseum
Valéria Marta Gomes de Lima,Nadia Krieger,Maria Inez de Moura Sarquis,David A. Mitchell,Luiz Pereira Ramos,José D. Fontana +5 more
TL;DR: In this paper, a wild fungal strain isolated from soybean oil and identified as Penicillium aurantiogriseum initially presented a volumetric lipase activity of 0.4 U/mL in submerged culture in a medium containing 0.5 % yeast extract and 1 % olive oil.
