由丝状菌引起的活性污泥膨胀仍然是世界各地污水处理厂的一个难题。膨胀是一个微生物学问题，因此只有在更好地了解它们的生态学，生理学和代谢之后，才可能在物种特定的基础上解决它。不依赖于培养的分子方法提供了关于这组生物体的许多有用信息，在这篇综述中，对所采用的方法和它们提供的信息进行了严格的评估。他们的应用，以了解膨胀所造成的最常见的长丝在日本，'钙。Kouleothrix '，在这里作为一个例子，这些技术可能被用来开发控制策略。现在可以获得一些负责膨胀的丝状菌的全基因组序列，因此可以理解为什么这些丝状菌可能在活性污泥工厂中茁壮成长，并提供有关最终如何具体控制它们的线索。
Activated sludge bulking caused by filamentous bacteria is still a problem in wastewater treatment plants around the world. Bulking is a microbiological problem, and so its solution on species‐specific basis is likely to be reached only after their ecology, physiology and metabolism is better understood. Culture‐independent molecular methods have provided much useful information about this group of organisms, and in this review, the methods employed and the information they provide are critically assessed. Their application to understanding bulking caused by the most frequently seen filament in Japan, ‘Ca. Kouleothrix’, is used here as an example of how these techniques might be used to develop control strategies. Whole genome sequences are now available for some of filamentous bacteria responsible for bulking, and so it is possible to understand why these filaments might thrive in activated sludge plants, and provide clues as to how eventually they might be controlled specifically.
