Fluorosis is an agonizing and crippling disease caused by fluoride intake. In the present study, fluorinated aqueous solution was treated with three novel bacterial strains viz., Bacillus sp. (GU566359), Rheinheimera sp. (GU566360) and Acinetobacter sp. (GU566361) isolated from potable waters of Mahabubnagar, Telangana State, India to screen the competence of potential bacteria for the removal of fluoride. SPADNS colorimetric method was adapted to measure fluoride concentration in broth media. Among the three bacteria studied Acinetobacter sp., showed 57.3% fluoride absorption efficacy after 10 h of incubation. Batch optimization studies revealed that the fluoride removal was optimum at pH 7.5, 35 °C and biosorbent dose of 40 mg/100 mL. Further the physicochemical characterization studies were confirmed that, morphology and functional groups of Acinetobacter sp. is suitable for removal of fluoride and therefore be used as a potential microbial species for endemic fluoride defluoridation applications in water.

氟中毒是由摄入氟化物引起的痛苦和残废的疾病。在本研究中，用三种新型细菌菌株，即芽孢杆菌属（Bacillus sp。）处理氟化水溶液。（GU566359），Rheinheimera藻。（GU566360）和不动杆菌属。（GU566361）从印度Telangana州Mahabubnagar的饮用水中分离出来，以筛选潜在细菌清除氟的能力。SPADNS比色法适用于测量肉汤培养基中的氟化物浓度。在所研究的三种细菌鲍曼不动在温育10小时后，其显示出57.3％的氟吸收效率。批次优化研究表明，在pH 7.5、35°C和40 mg / 100 mL生物吸附剂量下，除氟效果最佳。进一步的理化特性研究证实了不动杆菌属的形态和功能基团。适用于去除氟化物，因此可用作水中特有氟化物脱氟应用的潜在微生物。
