Apr 18, 2019· Using Microbial Communities to Predict Disease. Microbiomes are important to human health and disease (Bourne et al., 2009). Indeed, there are many microbial communities in the human body. Once a microbial community is out of balance or foreign microorganisms invade, the human body is likely to get sick.

Abstract. Industrial-scale mining of deep-sea polymetallic nodules will remove nodules in large areas of the sea floor. The regrowth of the nodules by metal precipitation is estimated to take millions of years. Thus, for future mining impact studies, it is crucial to understand the role of nodules in shaping microbial diversity and function in deep-sea environments.
