Abstract |
: |
The cyclic ether 1,4 dioxane is a carcinogenic, emerging micropollutant present in water and wastewater. The treatment methods are ineffective due to its high solubility (low Henrys law constant 5 x 10-6 atm m3/ mol) and also its heterocyclic structure (with two linear ethers). The present study was focused on biodegradation of 1,4 dioxane by a bacterial consortium enriched from 1,4 dioxane contaminated industrial sludge. The Bacterial consortium degraded 74% of 1,4 dioxane in 72 h. To enhance the biodegradation process, additional carbon substrates such as glucose, yeast extract and tetrahydrofuran (THF) were used. Among those carbon substrate, THF acts as a best substrate in accelerating the biodegradation process for complete degradation of 1,4 dioxane and also reducing the time taken for biodegradation. Yeast extract as additional substrate showed 92% of 1,4 dioxane degradation in 72 h whereas glucose showed 59% degradation in 72 h and also extended the time taken for complete degradation of 1,4 dioxane which was at 168 h. Further, the bacterial strains present in the consortium were identified as: bacterium enrichment culture clone strain AYS1 (JQ419749), Runella sp. AYS2 (JQ419750), Achromobacter sp. AYS3 (JQ419751), Marinobacter sp. AYS4 (JQ419752) and Rhodanobacter sp. AYS5 (JQ419753) using molecular techniques. |
