Abstract

Shewanella is a microbial group with high potential to be applied in textile effluents bioremediation due to its ability to use a wide variety of substrates as a final electron acceptor in respiration. The present research aimed to describe a new strain, Shewanella algae 2NE11, a decolorizing bacterium isolated from industrial effluent in Peru. S. algae 2NE11 showed an optimal growth under pH 6-9, temperature between 30-40 °C, and 0-4 % NaCl. It can tolerate high concentrations of NaCl until 10% and low temperatures as 4 °C. It decolorizes azo and anthraquinone dyes with a decolorization rate of 89-97%. We performed next-generation sequencing (Pacific Bioscience®) and achieved its complete genome sequence with a length of 5,030,813bp and a GC content of 52.98%. Genomic characterization revealed the presence of protein-coding genes related to decolorization like azoreductase, dyp-peroxidase, oxidoreductases, and the complete Mtr respiratory pathway. Likewise, we identified other properties such as the presence of metal resistant genes, and genes related to lactate and N-acetylglucosamine metabolism. These results highlight its potential to be applied in the bioremediation of textile effluents and guide future research on decolorization metabolic pathways.

摘要

希瓦氏菌是一类具有很高应用潜力的微生物,可用于纺织废水的生物修复,因为它能够利用多种底物作为呼吸作用中的最终电子受体。本研究旨在描述一种新菌株——希瓦氏藻2NE11,这是一种从秘鲁工业废水中分离出的脱色细菌。希瓦氏藻2NE11在pH值为6至9、温度在30至40°C以及NaCl浓度为0至4%的条件下生长最佳。它能够耐受高达10%的高浓度NaCl以及低至4°C的低温。它对偶氮染料和蒽醌染料具有脱色能力,脱色率为89%至97%。我们进行了二代测序(太平洋生物科学公司®),并获得了其完整的基因组序列,长度为5,030,813bp,GC含量为52.98%。基因组特征分析揭示了与脱色相关的蛋白质编码基因的存在,如偶氮还原酶、二酚过氧化物酶、氧化还原酶以及完整的Mtr呼吸途径。同样,我们还鉴定出了其他特性,如金属抗性基因的存在,以及与乳酸和N-乙酰葡糖胺代谢相关的基因。这些结果突出了其在纺织废水生物修复中的应用潜力,并为未来关于脱色代谢途径的研究提供了指导。
