Heterotrophic bacteria are an integral part of any environmental biotechnology process (EBP). Therefore, factors controlling bacterial abundance, activity, and community composition are central to the understanding of such processes. Among these factors, top-down control by bacteriophage predation has so far received very limited attention. With over 10(8) particles per ml, phage appear to be the most numerous biological entities in EBP. Phage populations in EBP appear to be highly dynamic and to correlate with the population dynamics of their hosts and genomic evidence suggests bacteria evolve to avoid phage predation. Clearly, there is much to learn regarding bacteriophage in EBP before we can truly understand the microbial ecology of these globally important systems.
异养细菌是任何环境生物技术过程 (EBP) 的一个组成部分。因此，控制细菌丰度、活性和群落组成的因素是理解这些过程的核心。在这些因素中，噬菌体捕食的自上而下控制迄今为止受到的关注非常有限。噬菌体的数量超过每毫升 10(8) 个，似乎是 EBP 中数量最多的生物实体。EBP 中的噬菌体种群似乎非常动态，并与宿主的种群动态相关，基因组证据表明细菌进化以避免噬菌体捕食。显然，在我们真正了解这些对全球重要系统的微生物生态学之前，还有很多关于 EBP 中噬菌体的知识需要学习。
