Abstract

The Lactococcus taiwanensis strain K_LL004 was isolated from the gut of a grasshopper (Oxya chinensis sinuosa) collected from local farm in Korea. L. taiwanensis strain K_LL004 is the functional probiotic candidate with an ability to hydrolyse plant polysaccharides. The complete genome of the L. taiwanensis strain K_LL004 contains one circular chromosome (1,995,099 bp) with a guanine + cytosine (GC) content of 38.8%. Moreover, 1,929 Protein-coding sequence, 19 rRNA genes, and 62 tRNA genes were identified based on results of annotation. L. taiwanensis strain K_LL004 has a gene, which encodes hydrolytic enzymes such as beta-glucosidase and beta-xylosidase, that hydrolyzes plant polysaccharides.

台湾乳球菌菌株K_LL004的全基因组序列，该菌株编码蝗虫植物多糖水解酶。

台湾乳球菌菌株K_LL004是从韩国当地农场采集的蚱蜢肠道中分离得到的。台湾乳杆菌菌株K_LL004是具有水解植物多糖能力的功能性候选益生菌。台湾L. ensis菌株K_LL004全基因组包含1条环状染色体(1,995,099 bp)，鸟嘌呤+胞嘧啶(GC)含量为38.8%。根据标注结果，鉴定出1929个蛋白编码序列、19个rRNA基因和62个tRNA基因。台湾乳杆菌菌株K_LL004具有一个编码水解植物多糖的酶，如-葡萄糖苷酶和-木糖糖苷酶的基因。

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).
