Distillery Spentwash Decolorization by a Noval Consortium of Pediococcus acidilactici and Candida tropicalis under Static Condition

Soni Tiwari, Rajeeva Gaur and Anurag Singh
The aim of this study was to isolate a consortium of bacterium and yeast from natural resources for better decolorization of distillery spentwash. Consortium exhibited 82±1.5% decolorization within 24 h when incubated at 45°C under static condition in effluent supplemented with 0.1%, glucose; 0.1%, peptone; 0.05%, MgSO4; 0.01%. The cultures were identified as Pediococcus acidilactici by 16S rDNA analysis and Candida tropicalis on the basis of phenotypic level. It is the first time when thermotolerant melanoidin decolorizing consortium (Pediococcus acidilactici and Candida tropicalis) isolated from distillery soil was capable to decolorizing melanoidin pigment of distillery effluent. Hence, it was observed that consortium has the ability to degrade the spentwash efficiently. This study could be an approach towards control of ecological pollution and health hazards of humans in and about the distillery location.
