    That these bacteria could reduce only 44% of the COD individually or collectively indicated that rest of the 56% COD of the spent wash was probably because of more recalcitrant organic compounds. The exploration of the genetic and molecular basis of degradation of such compounds would be required for developing microbial technologies for the improved treatment of distillery spent wash.
