Development of four-stage moving bed biofilm reactor train with a pre-denitrification configuration for the removal of thiocyanate and cyanate.

abstract：:Three phenol- and alkanes-degrading bacterial strains were isolated from a freshwater sample. Upon the 16S rRNA gene analysis, phenotype and physiological features, the three strains were designated as Acinetobacter sp. with both phenol hydroxylase gene (phe) and alkane monooxygenase gene (alkM) detected. They could s...
