Sustainable agriculture remains a focus for many researchers, in an effort to minimize environmental degradation and climate change. The use of plant growth promoting microorganisms (PGPM) is a hopeful approach for enhancing plant growth and yield. However, the technology faces a number of challenges, especially inconsistencies in the field. The discovery, that microbial derived compounds can independently enhance plant growth, could be a step toward minimizing shortfalls related to PGPM technology. This has led many researchers to engage in research activities involving such compounds. So far, the findings are promising as compounds have been reported to enhance plant growth under stressed and non-stressed conditions in a wide range of plant species. This review compiles current knowledge on microbial derived compounds, taking a reader through a summarized protocol of their isolation and identification, their relevance in present agricultural trends, current use and limitations, with a view to giving the reader a picture of where the technology has come from, and an insight into where it could head, with some suggestions regarding the probable best ways forward.
可持续农业仍然是许多研究人员关注的焦点，旨在尽量减少环境退化和气候变化。使用促进植物生长的微生物（PGPM）是提高植物生长和产量的一种有前景的方法。然而，这项技术面临着许多挑战，尤其是在田间效果不稳定。发现微生物衍生化合物可以独立促进植物生长，这可能是朝着减少与PGPM技术相关的不足迈出的一步。这促使许多研究人员开展涉及此类化合物的研究活动。到目前为止，研究结果很有希望，因为据报道，这些化合物能在各种植物物种的胁迫和非胁迫条件下促进植物生长。本综述汇编了关于微生物衍生化合物的现有知识，引导读者了解其分离和鉴定的简要流程、它们在当前农业趋势中的相关性、当前的用途和局限性，以便让读者了解该技术的起源，并洞察其未来发展方向，同时就可能的最佳前进方向提出一些建议。
