Abstract

Lactococcus taiwanensis starin K_LL001 was isolated from the gut of grasshopper (Oxya chinensis sinuosa). In this study, we presented the complete genome sequence of L. taiwanensis stain K_LL001. The genome of K_LL001 genome was composed of 1 circular chromosome without plasmids. The length of the whole genome was 2,018,259bp, guanin + cytosine (G±C) content (%) was 38.75%, with 2,021 predicted protein-coding sequences (CDS). The most abundant CAZyme class in L. taiwanensis strain K_LL001 was glycoside hydrolases (GH) class. GHs is the key enzymes involved in carbohydrate metabolism, and they catalyze the hydrolysis of glycosidic bonds in complex carbohydrates such as cellulose, hemicellulose, and starch. Moreover, L. taiwanensis strain K_LL001 has genes encoding enzymes which can catalyze the transformation of one glycoside to another. Overall, this study will contribute to a further understanding of L. taiwanensis strain K_LL001 at the genomic level and provide a theoretical basis for its future application in swine industry.

具有纤维素降解功能的台湾乳球菌菌株K_LL001的基因组分析

<italic>台湾乳球菌</italic>starin K_LL001是从蚱蜢肠道中分离出来的(<italic>Oxya chinensis sinuosa</italic>)。在这项研究中，我们提出了<斜体>L的全基因组序列。台湾</italic>stain K_LL001。K_LL001基因组由1条环状染色体组成，不含质粒。全基因组长度为2018,259 bp，鸟嘌呤+胞嘧啶(G±C)含量(%)为38.75%，预测蛋白编码序列(CDS)为2021条。最丰富的CAZyme类<斜体>L。taiwanensis< / italic>菌株K_LL001为糖苷水解酶(GH)类。GHs是参与碳水化合物代谢的关键酶，它们催化纤维素、半纤维素和淀粉等复杂碳水化合物中糖苷键的水解。此外,& lt; italic> L。taiwanensis< / italic>菌株K_LL001具有编码酶的基因，可以催化一种糖苷转化为另一种糖苷。总的来说，本研究将有助于进一步理解< italit>L。在基因组水平上对菌株K_LL001进行研究，为其未来在养猪业中的应用提供理论依据。

期刊介绍： Journal of Animal Science and Technology (J. Anim. Sci. Technol. or JAST) is a peer-reviewed, open access journal publishing original research, review articles and notes in all fields of animal science. Topics covered by the journal include: genetics and breeding, physiology, nutrition of monogastric animals, nutrition of ruminants, animal products (milk, meat, eggs and their by-products) and their processing, grasslands and roughages, livestock environment, animal biotechnology, animal behavior and welfare. Articles generally report research involving beef cattle, dairy cattle, pigs, companion animals, goats, horses, and sheep. However, studies involving other farm animals, aquatic and wildlife species, and laboratory animal species that address fundamental questions related to livestock and companion animal biology will also be considered for publication. The Journal of Animal Science and Technology (J. Anim. Technol. or JAST) has been the official journal of The Korean Society of Animal Science and Technology (KSAST) since 2000, formerly known as The Korean Journal of Animal Sciences (launched in 1956).
