Comparative Study on N and P Removal Ability of Chlorella pyrenoidosa and Scenedesmus obliquus
摘要
Abstract
Artificial medium with different nitrogen and phosphorus concentrations was designed to study N,P removal ability of Chlorella pyrenoidosa and Scenedesmus obliquus .Results showed that C. pyrenoidosa and S .obliquus could grow in all artificial media.However,growth rate of C.pyrenoidosa was the highest (0.505 /d)in the artificial medium with total nitrogen (TN)of 13 mg/L and total phos-phorus (TP)of 2 mg/L,which was significantly higher than that of S .obliquus with a maximum growth rate of 0.266 /d (P <0.05).Chlorophyll a syntheses of two microalgae were greatly influenced by artifi-cial media with different nitrogen and phosphorus concentrations.The maximum chl a yields (YN and YP) of C.pyrenoidosa were 7.72μg/mg and 51 .20μg/mg,respectively,in the artificial medium with TN of 13 mg/L and TP of 2 mg/L.While chl a yields (YN and YP)of S .obliquus were only 1 .14μg/mg and 14.78μg/mg,respectively,in the artificial medium with 18.2 mg/L TN and 2.8 mg/L TP.In addi-tion,total nitrogen removal efficiencies in artificial media were all above 97% using C.pyrenoidosa and S .obliquus .But C.pyrenoidosa has higher removal rate of total nitrogen than S .obliquus .Total phos-phorus removal efficiencies were obviously enhanced with the decrease of phosphorus concentration in arti-ficial medium.In general,C.pyrenoidosa was superior to S .obliquus in N,P purification.关键词
