Abstract

Leptospirillum ferriphilum Sp-Cl is a Gram negative, thermotolerant, curved, rod-shaped bacterium, isolated from an industrial bioleaching operation in northern Chile, where chalcocite is the major copper mineral and copper hydroxychloride atacamite is present in variable proportions in the ore. This strain has unique features as compared to the other members of the species, namely resistance to elevated concentrations of chloride, sulfate and metals. Basic microbiological features and genomic properties of this biotechnologically relevant strain are described in this work. The 2,475,669 bp draft genome is arranged into 74 scaffolds of 74 contigs. A total of 48 RNA genes and 2,834 protein coding genes were predicted from its annotation; 55 % of these were assigned a putative function. Release of the genome sequence of this strain will provide further understanding of the mechanisms used by acidophilic bacteria to endure high osmotic stress and high chloride levels and of the role of chloride-tolerant iron-oxidizers in industrial bioleaching operations.

摘要

嗜铁钩端螺旋菌Sp-Cl是一种革兰氏阴性、耐热、弯曲的杆状细菌，从智利北部的一个工业生物浸出作业中分离得到，在该作业中，辉铜矿是主要的铜矿物，矿石中还含有不同比例的碱式氯化铜氯铜矿。与该物种的其他成员相比，该菌株具有独特的特征，即对高浓度的氯离子、硫酸根离子和金属具有抗性。本文描述了这种具有生物技术相关性的菌株的基本微生物学特征和基因组特性。该菌株2,475,669 bp的草图基因组被组装成74个重叠群的74个支架。通过注释预测共有48个RNA基因和2,834个蛋白质编码基因；其中55%被赋予了假定的功能。该菌株基因组序列的发布将有助于进一步了解嗜酸细菌耐受高渗透胁迫和高氯水平的机制，以及耐氯铁氧化菌在工业生物浸出作业中的作用。
