Clavulanic acid production processes in a tower bioreactor with immobilised cells
(Elsevier B.V. Sa, 2008-04-01)
The feasibility of using Streptomyces clavuligerus ATCC 27064 bioparticles supported on alginate gel containing alumina to produce clavulanic acid (CA) was investigated. To this end, effectiveness factors for spherical ...
Photoeletrolytic system applied to remazol red brilliant degradation
(I W A Publishing, 2011-01-01)
Toxicity tests using Sacharomycces cerevisiae were made with simulated textile effluents containing reactive dye (remazol red brilliant) treated by photoeletrolytic process, varying treatment time and applied current. The ...

Neste estudo avaliou-se o desempenho de um reator anaeróbio operado em batelada sequencial, em escala piloto, com volume total de 280 L, no tratamento de águas residuárias de suinocultura. As cargas orgânicas volumétricas ...
Copper‑exchanged Y zeolites for gasoline deep‑desulfurization
(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. ...
