摘要 Reactive Blue-19 (RB19) 是一种蒽醌基乙烯基砜染料，由于其蒽醌结构通过共振稳定，因此很难被化学氧化降解。它对纤维素（棉纺织品）有 75-80% 的固色效率，未固色的染料可在环境中长期存在。因此，需要处理含有大量活性蓝 (RB) 19 染料的纺织工业废水。微生物燃料电池 (MFC) 是使用细菌从纺织废水中产生能量（电-生物电）的最新方法。在这项研究中，含有活性蓝 19 (RB19) 染料（50 毫克/升至 800 毫克/升）的合成纺织废水用于与新分离的产电细菌克雷伯氏菌一起发电。C。MFC 产生 533 mA/m2 的电流密度和 84 mW/m2 的功率密度。克雷伯氏菌的脱色效率。在优化条件下，RB19 的 C 在 24 小时内为 90%，即 pH 7、温度 37 °C、6 g/L 葡萄糖浓度和葡萄糖微生物比 60。 GCMS 分析鉴定的中间体包括草酸、茚-1、 3-二酮和氢醌。这些结果表明克雷伯菌属。C 可以被认为是一种用于发电的新细菌，同时处理含 RB19 的污水。茚- 1, 3- 二酮和氢醌。这些结果表明克雷伯菌属。C 可以被认为是一种用于发电的新细菌，同时处理含 RB19 的污水。茚- 1, 3- 二酮和氢醌。这些结果表明克雷伯菌属。C 可以被认为是一种用于发电的新细菌，同时处理含 RB19 的污水。

Biodegradation of reactive blue 19 with simultaneous electricity generation by the newly isolated electrogenic Klebsiella sp. C NCIM 5546 bacterium in a microbial fuel cell

Abstract Reactive Blue-19 (RB19) is an anthraquinone based vinylsulphone dye, which is very difficult to degrade by chemical oxidation because its anthraquinone structure is stabilized by resonance. It has 75–80% fixation efficiency on the cellulose (cotton textiles) and the unfixed dye persists in the environment for long periods. Therefore, textile industry effluents containing reactive blue (RB) 19 dye in a significant concentration need to be treated. Microbial fuel cell (MFC) is the newest approach for generating energy (electricity-bioelectricity) from the textile wastewater using bacteria. In this study, synthetic textile wastewater containing Reactive Blue 19 (RB19) dye (50 mg/L to 800 mg/L) was used to generate electricity with the newly isolated electrogenic bacterium Klebsiella sp. C. The MFC produced the current density of 533 mA/m2 and power density of 84 mW/m2. The decolorisation efficiency by Klebsiella sp. C for RB19 was 90% within 24 h under optimised conditions i.e. pH 7, temperature of 37 °C, 6 g/L glucose concentration and glucose to microbe ratio of 60. The intermediates identified by GCMS analysis included oxalic acid, indene- 1, 3- dione and hydroquinone. These results indicated that Klebsiella sp. C could be considered as a new bacterium for electricity generation along with treatment of RB19 containing effluent.
