Use of Viscosity to Probe the Interaction of Anionic Surfactants with a Coagulant Protein from Moringa oleifera Seeds
Pages 10

Introduction Moringa oleifera is a multipurpose tropical tree with most of its parts being useful for medicinal and commercial applications in addition to its nutritional value [1-8]. e seeds from this plant contain active coagulating agents characterized as dimeric cationic proteins having a molecular weight of 13 kDa and an isoelectric pH between 10 and 11 [2]. It is suggested that in the near future, coagulating protein extracted from Moringa oleifera seeds could be a potential challenger of synthetic coagulants (e.g., iron chloride and aluminium sulphate) for water puri-cation [3] and for primary treatment of industrial and domestic wastewaters [9]. As a result, it has been recommended by the Food and Agricultural Organization (FAO) as a proper and advisable way for treating water [8]. Recently, protein extract from Moringa oleifera seeds has been found to be an anionic surfactantremoval agent in aqueous solutions [4]. us, it is important to keep on researching on protein extracts from Moringa’s properties.
