PublicaçãoCapítulo de livro Nano-phytoremediation: The successful combination of nanotechnology and phytoremediation(2023-02-13) Zanatta, Melina Borges Teixeira
; de Oliveira, Maycon Lucas ; Souza, Lilian Rodrigues Rosa ; Universidade Estadual Paulista (UNESP) ; Universidade de São Paulo (USP) Environmental pollution is a recurrent problem since anthropogenic actions constantly expose the environment to toxic compounds. In view of this fact, many decontamination methodologies have been developed such as thermal treatment, oxidation, ion exchange, and others. Among these methods, phytoremediation has the advantage to be a green methodology (since it is employed plants for the remediation) and can efficiently degrade, stabilizes, or accumulates both inorganic and organic pollutants. Nowadays, nanomaterials and some microorganisms have been used combined with phytoremediation in order to improve the remediation and this new approach is called nano-phytoremediation. This chapter discusses the nanomaterials and microorganisms combined with phytoremediation besides explores the mechanisms of remediation of nano-phytoremediation for some nanomaterials combined with plants.PublicaçãoCapítulo de livro Yeast for pentose fermentation: Isolation, screening, performance, manipulation, and prospects(2017-01-01) Ceccato-Antonini, Sandra Regina ; Codato, Carolina Brito ; Martini, Cristina; Bastos, Reinaldo Gaspar ; Tauk-Tornisielo, Sâmia Maria ; Universidade Federal de São Carlos (UFSCar) ; Universidade Estadual Paulista (UNESP) The global demand for energy has led the research and the investments to use plant biomass to convert the sugars contained in this material into ethanol. The characteristics of the substrate and process have a strong impact on the choice of microorganisms to be used for fermentation of the sugars. In the most of feedstocks for ethanol production, the sugars containing five carbons (pentoses) are abundant. Naturally occurring yeasts that can use pentoses as carbon source have been isolated from the environment, and among them, Pichia stipitis is one of the most important species. However, some important characteristics needed in ethanol industry are high resistance to inhibiting compounds and high fermentation performance and, until this moment, none a single strain that gather these features has not been found naturally. Techniques of evolutionary engineering and genetic manipulation have been applied to introduce and select the required traits for pentose fermentation in Saccharomyces cerevisiae, the most employed yeast industrially. This chapter discusses the context of the microorganisms, especially the yeast group, in the fermentation of hemicellulosic substrates for bioethanol production regarding isolation, screening, performance, limitations, prospects, and state of the art, trying to contribute to the improvement of the global process of ethanol production.
