Sulfamethoxazole and ciprofloxacin removal using a horizontal-flow anaerobic immobilized biomass reactor
(Environmental Technology, 2015-10-14)
The antibiotics sulfamethoxazole (SMTX) and ciprofloxacin (CIP) are commonly used in human and veterinary medicine, which explains their occurrence in wastewater. Anaerobic reactors are low-cost, simple and suitable ...
Evaluation of sulfamethazine removal kinetics using fixed structured bed bioreactor
(2017-12-20)
The use of anaerobic biomass attached to a support has been recently presented as a good prospect in the treatment of wastewater containing recalcitrant compounds, such as sulfamethazine (SMZ). SMZ has been found in swine ...
Assessment of novel C-4 methylated tetraketide by HPLC-SPE-TT in saccharicola sp., an endophytic fungus in Eugenia Jambolana Lam
(2019-01-01)
A new compound named methyl (6S,7S,2E,4E)-6,7-dihydroxy-4,6-dimethyl octanoate was isolated from Saccharicola sp. using high performance liquid chromatography-solid phase extraction-transfer tube (HPLC-SPE-TT), together ...
High xylose yield from stem and external fraction of sugarcane biomass by diluted acid pretreatment
(2020-01-01)
Lignocellulosic materials are complex, recalcitrant, and difficult to release fermentable carbohydrates, such as xylose. Xylose is the feedstock for the development of products with high added value, such as ethanol, ...
Analysis of fluoxetine and norfluoxetine in human plasma by HPLC-UV using a high purity C18 silica-based SPE sorbent
(2014)
This paper reports on the development and validation of a simple and sensitive method that uses solid phase extraction (SPE) and liquid chromatography with ultraviolet detection to analyze fluoxetine (FLX) and norfluoxetine ...
Elaboración de helados mantecados y de paleta con base en tubérculos andinos (camote, oca y zanahoria blanca)
(Universidad de Cuenca, 2022-11-22)
The Andean tubers have been part of the diet of our ancestors in the Ecuadorian
highlands in different recipes and under different ways of consuming them, being
the pampa mesa the most common. Sweet potato, goose and ...
Thermal Parameters Analysis During Directional Solidification Of Al-Cu Eutectic Alloys
(Wiley, 2014-03)
Al-Cu eutectic alloy samples (Al-33.2wt.%Cu) were solidified directionally upward under conditions which produce the columnar-to-equiaxed transition (CET) phenomenon. The position of the CET was located in each sample and ...
Studies in Diatrypaceae: the new species Eutypa microasca and investigation of ligninolytic enzyme production
(Verlag Ferdinand Berger Sohne Gesellschaft Mbh, 2014-06)
In this study the extracellular production of ligninolytic enzymes by xylariaceous and diatrypaceous species from Argentina was investigated. Among them, a new species (Eutypa microasca) was evaluated. Its morphological ...
Influência dos íons metálicos na atividade e estabilidade de (hemi)celulases e no processo de sacarificação da biomassa
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2015-02-26)
The enzymes involved in the conversion process of lignocellulosic biomass into second generation (2G) ethanol add a high cost to the process. Studies reported in the literature indicate that some metal ions, easily found ...
