The aim of this work was to analyse the coagulant and antibacterial activities of lectin isolated from Moringa oleifera seeds that are used for water treatment.
The water-soluble M. oleifera lectin (WSMoL) was separated from nonhemagglutinating components (NHC) by chitin chromatography. WSMoL fluorescence spectrum was not altered in the presence of ions that are often present in high concentrations in polluted waters. Seed extract, NHC and WSMoL showed coagulant activity on a turbid water model. Both NHC and WSMoL reduced the growth of Staphylococcus aureus, but only WSMoL caused a reduction in Escherichia coli. WSMoL was also more effective in reducing the growth of ambient lake water bacteria.
Data obtained from this study indicate that WSMoL is a potential natural biocoagulant for water, reducing turbidity, suspended solids and bacteria.
Moringa oleifera seeds are a material effective in the treatment of water.
本研究旨在分析从用于水处理的辣木种子中分离出的凝集素的凝血和抗菌活性。
通过几丁质层析从非血凝成分（NHC）中分离出水溶性辣木凝集素（WSMoL）。存在于受污染水中高浓度的离子存在时，WSMoL 的荧光光谱没有改变。种子提取物、NHC 和 WSMoL 对浊水模型表现出凝血活性。NHC 和 WSMoL 均能抑制金黄色葡萄球菌的生长，但只有 WSMoL 能抑制大肠杆菌的生长。WSMoL 对减少环境湖水细菌的生长也更有效。
本研究获得的数据表明，WSMoL 是一种有潜力的天然水生物凝结剂，可降低浊度、悬浮物和细菌。
辣木种子是一种有效的水处理材料。
