This study focused on the identification of free cyanide (CDO) and thiocyanate (TDO) degrading microbial communities using a culturedependent and independent approach. Culturable microbial species were isolated from the CDOs (n = 13) and TDOs (n = 18). The CDOs were largely dominated by Bacillus sp. while the TDOs were dominated by Bacillus sp., Klebsiella oxytoca, Providencia sp. and ...
