Fig. 8From: Hydrolytic denitrification and decynidation of acrylonitrile in wastewater with Arthrobacter nitroguajacolicus ZJUTB06-99Influence of reaction time on acrylonitrile biodegradation rate. The concentration of acrylonitrile was constantly decreasing with the increase of time. After 8 h, the residual of acrylonitrile decreased slowly and gradually became stable. The optimum biodegradation time was determined to be 8 hBack to article page
