Potential for Waste Reduction in Activated Sludge Systems: Evaluation of the Initial Conditions of a Rapid Test with Rhamnolipid Biosurfactant
Autor: Verônica M. F. Alexandre, Melissa L. E. Gutarra, Denise M. G. Freire, Magali C. Cammarota
Publikováno v: Journal of Sustainable Development of Energy, Water and Environment Systems, Vol 7, Iss 4, Pp 702-715 (2019)
Adding chemicals that alter the microbial metabolism and reduce cell growth, without affecting organic matter removal, is an alternative technology to reduce sludge production. This study was intended to determine the best initial conditions to condu

A Pesticide Biopurification System: A Source of Biosurfactant-Producing Bacteria with Environmental Biotechnology Applications
Autor: Claudio Lamilla, Heidi Schalchli, Gabriela Briceño, Bárbara Leiva, Pamela Donoso-Piñol, Leticia Barrientos, Vanessa A. L. Rocha, Denise M. G. Freire, M. Cristina Diez
Publikováno v: Agronomy, Vol 11, Iss 4, p 624 (2021)
Biosurfactants, a wide group of compounds produced by different microorganisms, generally have less toxicity and are more biodegradable than synthetic surfactants. Biosurfactant-producing bacteria can be found in contaminated environments, such as so

Olive Oil Oleogel Formulation Using Wax Esters Derived from Soybean Fatty Acid Distillate
Autor: Aikaterini Papadaki, Nikolaos Kopsahelis, Denise M. G. Freire, Ioanna Mandala, Apostolis A. Koutinas
Publikováno v: Biomolecules, Vol 10, Iss 1, p 106 (2020)
Oleogelation is an emerging technology to structure oils, which can be widely used to substitute saturated and trans fats. Extra virgin olive oil is widely recognized for its high nutritional value, but its utilization in oleogel production is curren

Streptomyces luridus So3.2 from Antarctic soil as a novel producer of compounds with bioemulsification potential.
Autor: Claudio Lamilla, Douglas Braga, Rui Castro, Carolina Guimarães, Livia V A de Castilho, Denise M G Freire, Leticia Barrientos
Publikováno v: PLoS ONE, Vol 13, Iss 4, p e0196054 (2018)
The present study aimed to identify novel microbial producers of bioemulsificant compounds from Antarctic soils. Fifty-nine microbial strains were isolated from five different locations at South Shetland Islands, Antarctica, and screened for biosurfa

Preparation of Polymer Microparticles Through Non-aqueous Suspension Polycondensations: Part VI—Analyses of Chemical and Enzymatic Degradation of Poly(Butylene Succinate) (PBS)
Autor: Eliane Pereira Cipolatti, Martina C. C. Pinto, Denise M. G. Freire, Mariana Franco, Rafael C. Lima, Evelin A. Manoel, Mariana S. Viana, Luciana Dutra, José Carlos Pinto
Publikováno v: Journal of Polymers and the Environment. 30:1893-1907
Two strategies were investigated to perform the controlled degradation of two grades of poly(butylene succinate) (PBS): the chemical and enzymatic degradation routes. PBS chemical degradation assays were carried out in alkaline and acidic media at th
