标题：Biotreatment of Textile Effluent for Irrigation Purpose Using Indigenous Bacterial Consortium (BMP1/SDSC/01): A Step towards Reducing Fresh Water Scarcity
摘要：A bioreactor was designed to attain efficient, cost-effective and environmentally reliable bioremediation system for the biotreatment of textile effluents to produce irrigation water. The consortium BMP1/SDSC-01 (having six indigenous bacterial isolates: Bacillus subtilus, Bacillus cereus, Bacillus mycoides, Bacillus sp., Micrococcus sp. and Pseudomonas sp.) was used in the bioreactor for the treatment of effluents. Bacterial obliteration from the biotreated textile effluents was done by using acetic acid, which proved efficient and result showed that bacterial growth was not possible in the presence of acetic acid. The treated and untreated textile effluents were applied on two common crops of Pakistan Zea mays L. CV C1415 (Maize) and Sorghum vulgare Pers.CV SSG5000 (Sorghum) to monitor efficacy of bioremediated textile effluents. During experiment plant height, number of leaves, photosynthesis and transpiration rates, and biomass were measured. The results clearly indicated that in untreated effluents maize plant height, biomass, photosynthesis and transpiration was93.26, 45.38, 9.11 and 0.41, respectively. Under irrigation of treated effluents, plant height, biomass, photosynthesis and transpiration were 124, 44.07, 16.95 and 0.84 respectively. Similar trend was observed in sorghum, its plant height increased to 115.8 instead of 85 (untreated). Simultaneously, number of leaves, biomass, photosynthesis and transpiration were 8.62, 44.45, 13.29 and 0.51, respectively. The results are proving that bioreactor successfully reduced the toxicity level of textile effluents and can be used for irrigation purposes. This study will help to produce irrigation water from textile effluents at large scale in Pakistan by applying bioremediation.
