Microbial removal of NOX at high temperature by a novel aerobic strain Chelatococcus daeguensis TAD1 in a biotrickling filter

► We optimized the medium of the recycling liquid by two statistical methods. ► We examined the efficiency of a biotrickling filter using TAD1 and optimal medium. ► TAD1 was stable in the biofilm. ► The biotrickling filter could treat NOX efficiently at high temperature.
