Comparison of conventional and extractive fermentation using aqueous two-phase system to extract fibrinolytic proteases produced by Bacillus stearothermophilus DPUA 1729
(2020-01-01)
Fibrinolytic enzymes have been considered promising for treatment and protection of healthy circulation due its ability to dissolve the fibrin in blood clots. Extractive fermentation is a not explored and efficient downstream ...
Multivariate Optimization of Pressurized Solvent Extraction of Alkylphenols and Alkylphenol Ethoxylates from Biosolids
(Sociedade Brasileira de Química, 2012)
In this study, a methodology for pressurized solvent extraction of alkylphenols (APs) and alkylphenol ethoxylates (APEOs) from biosolids was optimized by utilizing a biosolid natively containing these compounds at a high ...
Understanding the extraction capabilities of the Helix Supercritical Fluid System
(Universidad EAFITIngeniería de ProcesosEscuela de Ingeniería. Departamento de Ingeniería Procesos, 2018)
Supercritical fluids extraction is a separation technique, which has higher yields and lower extraction times than conventional extraction techniques -- Moreover, due to the general use of carbon dioxide a supercritical ...
Ultrasound-assisted pressurized solvent extraction for aliphatic and polycyclic aromatic hydrocarbons from soils
(ELSEVIER, 2006-11-03)
In the present work the efficiency of extraction of aliphatic diesel range organics (DROs) and polycyclic aromatic hydrocarbons (PAHs) from soil was assessed by using dynamic modes of pressurized solvent extraction (PSE), ...
