许多微生物生活在低于最佳温度的环境中。通过聚集或绝缘保持代谢热将促进生长。产生多余的代谢热也可能提供好处。产生多余代谢热的细胞支付生产成本，而在局部热捕获区域内的邻居可以分享收益。代谢热作为一种可共享的公共产品提出了关于热生产和捕获的冲突与合作的有趣问题。代谢热也可以作为一种武器。耐热性较强的物种通过提高当地温度来战胜耐热性较差的分类群。代谢热可以提供防御噬菌体的攻击，类似于脊椎动物的发烧。本文概述了微生物冲突与合作中的代谢热理论，并对未来的研究提出了几点预测。
Many microbes live in habitats below their optimum temperature. Retention of metabolic heat by aggregation or insulation would boost growth. Generation of excess metabolic heat may also provide benefit. A cell that makes excess metabolic heat pays the cost of production, whereas the benefit may be shared by neighbors within a zone of local heat capture. Metabolic heat as a shareable public good raises interesting questions about conflict and cooperation of heat production and capture. Metabolic heat may also be deployed as a weapon. Species with greater thermotolerance gain by raising local temperature to outcompete less thermotolerant taxa. Metabolic heat may provide defense against bacteriophage attack, by analogy with fever in vertebrates. This article outlines the theory of metabolic heat in microbial conflict and cooperation, presenting several predictions for future study.
