The first documented study on bacterial predation was carried out using myxobacteria three quarters of a century ago. Since then, many predatory strains, diverse hunting strategies, environmental consequences and potential applications have been reported by groups all over the world. Now we know that predatory bacteria are distributed in a wide variety of environments and that interactions between predatory and non-predatory populations seem to be the most important factor in bacterial selection and mortality in some ecosystems. Bacterial predation has now been proposed as an evolutionary driving force. The structure and diversity of the predatory bacterial community is beginning to be recognized as an important factor in biodiversity due to its potential role in controlling and modelling bacterial populations in the environment. In this paper, we review the current understanding of bacterial predation, going over the strategies used by the main predatory bacteria to kill their prey. We have also reviewed and integrated the accumulated advances of the last 75 years with the interesting new insights that are provided by the analyses of genomes, predatomes, predatosomes and other comparative genomics studies, focusing on potential applications that derive from all of these areas of study.
四分之三个世纪前，首次有文献记载的关于细菌捕食的研究是利用黏细菌开展的。从那时起，世界各地的研究团队报告了许多捕食性菌株、多样的捕食策略、环境影响及潜在应用。如今我们知道，捕食性细菌分布于各种各样的环境中，而且在某些生态系统中，捕食性与非捕食性种群之间的相互作用似乎是细菌选择和死亡的最重要因素。细菌捕食现已被认为是一种进化驱动力。捕食性细菌群落的结构和多样性开始被视为生物多样性的一个重要因素，因为它在控制和模拟环境中的细菌种群方面具有潜在作用。在本文中，我们回顾了目前对细菌捕食的认识，阐述了主要捕食性细菌用于杀死猎物的策略。我们还回顾并整合了过去75年积累的进展以及基因组、捕食组、捕食体和其他比较基因组学研究分析所提供的有趣新见解，重点关注源自所有这些研究领域的潜在应用。
