Adsorptive desulfurization of heavy naphthenic oil: Equilibrium and kinetic studies
A.M. Moreira,Heloisa de Lima Brandão,Fabíola V. Hackbarth,Danielle Maass,A. A. Ulson de Souza,S. M. A. Guelli U. Souza +5 more
TL;DR: In this article, an experimental desulfurization of naphthenic oils using activated carbon was conducted in an adsorption system at different temperatures, and the adsorptive capacity and selectivity of the adsorbent for sulfur compounds and the effects of coexisting inhibitors were examined.

Bioconversion of low-cost brewery waste to biosurfactant: An improvement of surfactin production by culture medium optimization
Talita Corrêa Nazareth,Conrado Planas Zanutto,Conrado Planas Zanutto,Danielle Maass,Antônio Augusto Ulson de Souza,Selene M.A. Guelli U. de Souza +5 more
TL;DR: In this paper, the effect of nitrogen sources on biosurfactant production was investigated by a full factorial design, where yeast extract and its interaction with peptone presented a statistically significant effect on the response variable of surface tension (ST).

The use of low-cost brewery waste product for the production of surfactin as a natural microbial biocide
Talita Corrêa Nazareth,Conrado Planas Zanutto,Conrado Planas Zanutto,Conrado Planas Zanutto,Lakshmi Tripathi,Abdulaziz Juma,Danielle Maass,Antônio Augusto Ulson de Souza,Selene M.A. Guelli U. de Souza,Ibrahim M. Banat +9 more
TL;DR: In this paper, Bacillus subtilis was used as a carbon source for surfactin and achieved a growth log reduction of 3.91 for Pseudomonas aeruginosa.

Biosynthesis of iron oxide nanoparticles from mineral coal tailings in a stirred tank reactor
TL;DR: In this paper, the authors studied the performance of Rhodococcus erythropolis ATCC 4277 free-cells in a stirred tank reactor for the extraction of residual iron from rhomboclase and its transformation into nanoparticles.
