    • Bioconversion of low-cost brewery waste to biosurfactant: an improvement of surfactin production by culture medium optimization 

      Corrêa Nazareth, Talita; Planas Zanutto, Conrado; Maass, Danielle [UNIFESP]; Ulson de Souza, Antônio Augusto; Guelli Ulson de Souza, Selene Maria de Arruda (Colin Webb, 2021-05-11)
      Trub is the second-largest residue from brewing industry (250 thousand tons/year) and, due to the presence of high amounts of carbon and nitrogen, it is a potential source of reducing sugars and nitrogen for biological ...

    • Biomining of iron-containing nanoparticles from coal tailings 

      Maass, Danielle [UNIFESP]; Machado, Morgana de Medeiros; Rovaris, Beatriz Cesa; Bernardin, Adriano Michael; Oliveira, Débora de; Hotza, Dachamir (Springer Nature, 2019-07-10)
      Sulfur minerals originating from coal mining represent an important environmental problem. Turning these wastes into value added by-products can be an interesting alternative. Biotransformation of coal tailings into ...

    • Biosynthesis of iron oxide nanoparticles from mineral coal tailings in a stirred tank reactor 

      Maass, Danielle [UNIFESP]; Valério, Alexsandra; Lourenço, Luís Antonio; Oliveira, Débora de; Hotza, Dachamir (Gamini Senanayake, 2019-01-23)
      Chemical oxidation of mineral coal tailings is one of the most important environmental issues during the lifetime of a mine. The presence of sulfur compounds favors the occurrence of metal acid leaching, which contaminates ...

    • Copper‑exchanged Y zeolites for gasoline deep‑desulfurization 

      Cerutti, Myriam L. M. Navarro; Hackbarth, Fabíola V.; Maass, Danielle [UNIFESP]; Chiaro, Sandra S. X.; Pinto, Ricardo R. C.; Cardoso, Mauri J. B.; Arroyo, Pedro A.; Souza, Antonio A. Ulson de; Souza, Selene M. A. G. Ulson de (Springer Nature, 2019-07-25)
      Adsorptive desulfurization is one of the most efficient methods to remove recalcitrant sulfur compounds from transportation fuels. Two π-complexation-based sorbents were studied for desulfurization of synthetic gasoline. ...

    • How Biomining has been Used to Recover Metals from Ores and Waste? A Review 

      Brandão, Igor Yannick das Neves Vasconcellos [UNIFESP]; Munakata, Atílio Akihiro [UNIFESP]; Lourenço, Luís Antonio; Maass, Danielle [UNIFESP] (Damir Bucković, 2021-11-18)
      The recovery of metals present in low-grade ores and waste of electrical and electronic equipment (WEEE) is essential for the development of new technologies and the supply of existing production chains. Conventional ...

    • Impact of oxygen supply on surfactin biosynthesis using brewery waste as substrate 

      Zanutto, Talita Corrêa Nazareth; Zanutto, Conrado Planas; Maass, Danielle [UNIFESP]; Souza, Antônio Augusto Ulson de; Souza, Selene Maria de Arruda Guelli Ulson de (Elsevier, 2021-03-15)
      This work reports surfactin production by B. subtilis ATCC 6051 in a stirred tank bioreactor, where trub was used as a carbon source. Trub is a residue from the brewing industry mainly composed of high-molar-mass proteins ...

    • A low‑cost brewery waste as a carbon source in bio‑surfactant production 

      Corrêa Nazareth, Talita; Planas Zanutto, Conrado; Maass, Danielle [UNIFESP]; Ulson de Souza, Antônio Augusto; Guelli Ulson de Souza, Selene Maria de Arruda (Dirk Weuster-Botz, 2021-06-22)
      This work aims to produce bio-surfactant using a brewery waste (trub) as a strategy to reduce production costs related to the substrate, as well as to provide an eco-friendly destination for this residue. Trub is obtained ...

    • The use of low-cost brewery waste product for the production of surfactin as a natural microbial biocide 

      Nazareth, Talita Corrêa; Zanutto, Conrado Planas; Tripathi, Lakshmi; Juma, Abdulaziz; Maass, Danielle [UNIFESP]; Souza, Antônio Augusto Ulson de; Souza, Selene Maria de Arruda Guelli Ulson de (Elsevier, 2020-10-07)
      Surfactin has potential as next generation antibiofilm agent to combat antimicrobial resistance against emerging pathogens. However, the widespread industrial applications of surfactin is hampered by its high production ...
