Abstract

Oceanimonas sp. NSJ1 was isolated from macroplastic debris collected previously from Junput, an intertidal beach, facing the northeast coastal Bay of Bengal of the Northern Indian Ocean. The genome of this isolate is closely related to Oceanimonas doudoroffii with a genome size of 3.56 Mbp. The genome annotation confirmed the presence of 5919 total genes, out of which 5809 were CDSs (coding sequences) and all are protein-coding. The genome codes for 110 RNA with 25 rRNA, 84 tRNA (transfer RNA), and one tmRNA (transfer-messenger RNA). Analyses of the annotated genome of Oceanimonas sp. NSJ1 revealed the presence of enzymes involved in the degradation of polycyclic aromatic hydrocarbons. The presence of phthalate 4,5-dioxygenase oxygenase reductase subunit pht2 within the genome also highlights the novelty of this isolate and future functional potential for studying phthalate degradation in marine environment.

在Nanopore Mineion平台上测序的一种与质体相关的Oceanimonas sp.NSJ1的基因组分析
Oceanimonas sp.NSJ1是从之前从Junput收集的大塑料碎片中分离出来的,Junput是一个潮间带海滩,面向北印度洋东北海岸孟加拉湾。该分离株的基因组大小为3.56Mbp,与杜多罗菲氏大洋藻(Oceanimonas doudoroffii)亲缘关系密切。基因组注释证实了5919个总基因的存在,其中5809个是CDSs(编码序列),并且都是蛋白质编码。基因组编码110个RNA,其中25个rRNA、84个tRNA(转移RNA)和一个tmRNA(转移信使RNA)。对Oceanimonas sp.NSJ1的注释基因组的分析揭示了参与多环芳烃降解的酶的存在。基因组中邻苯二甲酸盐4,5-二氧合酶加氧酶还原酶亚基pht2的存在也突出了该分离物的新颖性和未来研究邻苯二酸盐在海洋环境中降解的功能潜力。
