Animals are an essential part of the ecosystem, and their carcasses are the nutrient patches or hotspots where nutrients accumulate for a long time. After death, the physical and chemical properties undergo alterations inside the carcass. The animal carcass is decomposed by many decomposers such as bacteria, fungi, microeukaryotes and insects. The role of microbial symbionts in living organisms is well explored and studied, but there is a scarcity of knowledge and research related to their role in decomposing animal carcasses. Microbes play an important role in carcass decomposition. The origins of microbial communities associated with a carcass, including the internal and external microbiome, are discussed in this review. The succession and methods used for the detection and exploration of decomposition-associated microbial communities have been briefly described. Also, the applications of carcass-associated microbial taxa have been outlined. This review is intended to understand the dynamics of microbial communities associated with the carcass and pave the way to estimate postmortem interval and its role in recycling nutrients.

探索动物尸体分解的微生物群落、评估方法和应用：综述

动物是生态系统的重要组成部分，它们的尸体是营养物质长期积累的营养斑块或热点。死后，胴体内部的物理和化学性质发生变化。动物尸体被许多分解者分解，如细菌、真菌、微真核生物和昆虫。微生物共生体在生物体中的作用得到了很好的探索和研究，但与它们在分解动物尸体中的作用相关的知识和研究却很少。微生物在屠体分解中起着重要作用。本综述讨论了与胴体相关的微生物群落的起源，包括内部和外部微生物组。简要描述了用于检测和探索分解相关微生物群落的演替和方法。此外，还概述了与胴体相关的微生物类群的应用。这篇综述旨在了解与尸体相关的微生物群落的动态，并为估计死后间隔及其在循环养分中的作用铺平道路。
