| Abstract: | In this paper the low-intensity ultrasound(LIU) group and the control group were employed to investigate the microbial degradation of NB with Rhodotorula mucilaginosa Z1,Streptomgces albidoflavus Z2 and Micrococcus luteus Z3 under different conditions.The operation conditions were optimized as 35 kHz,180 W and 15 min for irradiation.Compared to control group,the NB removals in LIU group were increased by 11.3%,7.9% and 1.3% in 96 h and the initial ultrasound effects were observed at 15 h,17 h and 16 h in co... |
