Foam Fractionation of Binary Mixtures of Lysozyme and Albumin

Enrichment behavior of immunoglobulin by foam fractionation using response surface methodology

“…Albumin is widely used and well-studied as a foaming agent because of its good foaming ability, stability and low cost [AHMAD 1975, ANAND and DAMODARAN 1995, CLARK, et al 1988, LOCKWOOD, et al 2000, NICOLAI, et al 2008, SCHNEPF and GADEN 1959. The target immunoglobulin (0.2-1.0 g), either rabbit IgG or human IgM, and albumin bovine (0.125-2.0 g) were added into an empty 1 L volumetric flask and dissolved with deionized water to the 1 L mark.…”

“…Albumin is used because of its good foaming ability, stability and low cost [AHMAD 1975, ANAND and DAMODARAN 1995, CLARK, et al 1988, LOCKWOOD, et al 2000, NICOLAI, et al 2008, SCHNEPF and GADEN 1959. The initial albumin bovine concentration was varied from 0.125 to 2 mg/mL, keeping all other parameters constant (initial pH value: 7; initial immunoglobulin concentration:…”

“…The current interest seems to indicate a desire for a low-cost, highly effective purification method for biological products, particularly in the first concentration step that is used to remove about 90% of the water from dilute solutions. Several papers further support these studies by providing a theoretical understanding and empirical observations of protein foam fractionation [HALLER, et al 2010, LINKE, et al 2007, LOCKWOOD, et al 2000, URAIZEE and NARSIMHAN 1990a, URAIZEE and NARSIMHAN 1990b.…”

Preparation of ceramic filler from reusing sewage sludge and application in biological aerated filter for soy protein secondary wastewater treatment

“…protein, sugar) and inorganic substances (e.g. salt, Cl − , and SO 4 2− ) [18], characterized by high COD, BOD [19,20] and SS due to the high protein content, which inevitably causes serious environment pollution. Currently, the studies on treating soy protein processing wastewater are mainly focused on biological technologies.…”

Foam fractionation in recovery of captopril

“…The application of foam fractionation to biological materials, such as proteins, enzyme etc., is very much attractive (8)(9)(10). Surfactants represent a striking problem in water resources.…”
