摘要/Abstract

摘要：

脂肪含量是影响家畜肉品质的主要因素之一。肌肉中的脂肪分布与肉的颜色、适口性、风味、嫩度和系水力等关系密切，肌内脂肪是评价肉品质的关键指标。肠道微生物和线粒体作为机体最庞大的微生态系统和细胞的“动力工厂”，在脂质代谢和细胞代谢间起到了重要的桥梁作用。目前，有关肠道微生物组及线粒体组的研究较为广泛，但两者的互作对脂肪沉积的影响尚不明确。本文通过综述肠道微生物及其代谢物功能与脂肪酸代谢，脂肪沉积与线粒体功能研究，以及肠道微生物及其代谢物与线粒体互作对脂肪沉积的调控机制，为通过肠道微生物及线粒体改善动物肉品质提供参考和思路。

Abstract:

Fat content is one of the main factors affecting the quality of livestock meat. The distribution of fat in muscles is closely related to the color, palatability, flavor, tenderness and hydration of meat, and intramuscular fat is regarded as a key indicator for evaluating meat quality. Intestinal microbiota and mitochondria, as the largest microecosystem and cellular "power factories" in the body, play important bridging roles between lipid metabolism and cellular metabolism. At present, research on the gut microbiome and mitochondria is relatively extensive, but the impact of their interaction on fat deposition is not yet clear. This article reviews the research on gut microbiota and their metabolite functions and fatty acid metabolism, fat deposition and mitochondrial function, as well as the regulatory mechanisms of gut microbiota and their metabolite interactions with mitochondria on fat deposition, in order to provide references and ideas for improving animal meat quality through gut microbiota and mitochondria.

Key words: gut microbiota, mitochondria, metabolite, fat deposition
