Microorganisms underpin life on Earth, but our understanding of their diversity and activity is limited by our inability to grow most of them in the laboratory. Recently, new techniques have emerged that allow access to the genetic information of all microorganisms by directly sequencing DNA and RNA from the environment. In this research we will further develop these frontier technologies, promoting this new area of science in Australia. We will apply these techniques to microbial communities involved in wastewater treatment in order to understand the interactions between microorganisms and the viruses that infect them. Understanding this interaction will have important implications for optimising these treatment processes.

微生物支撑着地球上的生命，但我们对它们的多样性和活性的了解受到限制，因为我们无法在实验室中培养它们中的大多数。最近，出现了新技术，通过直接对环境中的DNA和RNA进行测序，可以获得所有微生物的遗传信息。在这项研究中，我们将进一步发展这些前沿技术，促进澳大利亚这一新的科学领域。我们将把这些技术应用于废水处理中涉及的微生物群落，以了解微生物和感染它们的病毒之间的相互作用。了解这种相互作用将对优化这些处理过程具有重要意义。
