Background Oats ( Avena sativa L.) are a potential economically viable source of lipids and starch for use in foods. The aim of this study was to determine the effect of treated and untreated urban wastewater on seed germination, growth parameters and lipase and amylase activities in A. sativa .Results Untreated wastewater was highly toxic in nature and had an inhibitory effect on seed germination and seedling growth. However, after bacterial treatment, its toxicity was significantly reduced and it showed improved seed germination. It was observed that treated wastewater had no inhibitory effect on seedling growth parameters. However, A. sativa seeds treated with untreated effluent showed reduced lipase and amylase activities.Conclusion Treated wastewater could be used for irrigation purposes provided that it satisfies other conditions fixed by legislation. © 2012 Society of Chemical Industry
