This paper describes the isolation of an algicidal strain, Stenotrophomonas rhizophila KC1, from mangrove (Kandelia candel) and its genome, which was sequenced using next-generation sequencing technology. The genome is 5.93 Mb with a G+C content of 63.17%. A total of 3,352 functional proteins were assigned according to Kyoto Encyclopedia of Genes and Genomes categories. A total of 11,586 protein-coding genes, 73 transfer RNA genes, and 17 ribosomal RNA genes were obtained. In silico genome annotation protocols identified 83 putative quorum sensing (QS) genes, and the algicidal potential of KC1 was related with the QS genes (for example LuxI-LuxR genes). Collectively, these data suggest that KC1 may be an antialgal bacterium whose behavior can be modulated by QS signaling. The annotated genome sequence of this strain may represent a valuable tool for studying algae-bacteria interactions and developing microbe-based methods for controlling harmful algae.

Stenotrophomonas rhizophila KC1 的完整基因组序列,一种从 Mangrove Kandelia candel 中分离的群体感应产藻细菌
本文介绍了从红树林 ( Kandelia candel ) 及其基因组中分离出一种杀藻菌株Stenophomonas rhizophila KC1,并使用新一代测序技术对其进行了测序。基因组为 5.93 Mb,G+C 含量为 63.17%。根据京都基因和基因组百科全书类别,总共分配了 3,352 个功能蛋白。共获得11,586个蛋白质编码基因、73个转移RNA基因和17个核糖体RNA基因。计算机基因组注释协议确定了 83 个假定的群体感应 (QS) 基因,KC1 的杀藻潜力与 QS 基因(例如LuxI-LuxR基因)。总的来说,这些数据表明 KC1 可能是一种抗藻细菌,其行为可以通过 QS 信号进行调节。该菌株的注释基因组序列可能是研究藻类-细菌相互作用和开发基于微生物的控制有害藻类方法的宝贵工具。
