“…There are other plant materials such as Jatropa curcus and Phaseolus vulgaris that possess coagulation activity have been reported and are considered to be a potential water treatment agent (Abidin et al 2013;Antov et al 2010Antov et al , 2012. However, the coagulation activity varies between the types of seed material used, extraction methods, initial turbidity of water, mixing, suspended particles, and ions present in the water samples (Okuda et al 2001;Ghebremichael et al 2005;Marobhe et al 2007a;Abidin et al 2013). Moreover, information on the exact nature of coagulant agent from other plant materials is scarce and needs further investigation.…”

“…), sugar maize and red maize (Zea mays sp.) (Gunaratna et al 2007), Jatropha curcas (Pritchard et al 2009;Abidin et al 2013), Nirmali seeds (Strychnos potatorum) (Babu and Chaudhuri 2005), chestnut and acorn (Š ćiban et al 2009) and Cassia angustifolia (Sanghi et al 2002) has been reported. Although several natural materials are reported to be potent coagulant agents, the usage has not become widespread, probably due to limited knowledge and scientific reports on point-ofuse technology (Yin 2010).…”

The use of natural coagulant protein in drinking water treatment has been discussed for a long time, though the method is still not in practice, probably due to limited knowledge and availability of material. In the present work, different Mustard varieties were tested for the presence of coagulant protein compared with Moringa seed extract and their potential application in water treatment. The coagulation activity of the protein extract was measured using synthetic clay solution as well as water from pond. The protein content was determined by Bradford method, molecular mass determined by Sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and peptide sequence was analyzed by Mass spectrometry. Extract of Mustard (large) and Moringa seed showed coagulation activity of %70 and %85 % after 90 min, respectively. Interestingly, seed extracts from other Mustard varieties had coagulation activity after heat activation at 95°C for 5 h. However, the coagulation activity of Mustard seed extract against turbid pond water was higher (%60 %) compared to Moringa seed extract (%50 %). The peptide sequence analysis of 6.5 and 9 kDa proteins was found to be homologous to Moringa coagulant protein and napin3, respectively. To our knowledge, this could be the first report on Mustard seed having coagulant protein. The coagulation activity of Mustard (large) against highly turbid pond water suggested that it could be a potential natural coagulant for water treatment.

“…The application of coagulation/flocculation process is applied in water, wastewater treatment to remove turbidity from drinking water [12]. The alternative proposed were the use of natural coagulants for pretreatment by several researchers [13][14][15][16][17]. In previous studies various plant material such as Moringa oleifera [18] the coagulationflocculation process using Moringa oleifera seeds after oil extraction was reported [19].…”

“…The usage of the current coagulants has disadvantages associated with the high acquisition costs, the production of high volumes of sludge, changes of water pH and alkalinity [9,10], possible relation with Alzheimer and some kinds of cancer [11,12], problems that could be minimized using natural coagulants that can be extracted from plants and animals, as well as some microorganisms [1,7,13,14]. Natural coagulants are mostly carbohydrates (polysaccharides) and proteins [15].…”
