Effects of Ocean Acidification on the Diversity and Activity of Heterotrophic Marine Microorganisms
Microbe-mediated processes are crucial for biogeochemical cycles and the functioning of marine ecosystems (Azam and Malfatti 2007 ). If these processes are affected by ocean acidification, major consequences can be expected for the functioning of the global ocean and the systems that it influences,...

Microbe-mediated processes are crucial for biogeochemical cycles and the functioning of marine ecosystems (Azam and Malfatti 2007 ). If these processes are affected by ocean acidification, major consequences can be expected for the functioning of the global ocean and the systems that it influences, such as the atmosphere. In contrast to phytoplankton, which have been relatively well studied (see Chapter 6), there is comparatively little information on the effect of ocean acidification on heterotrophic microorganisms. Two reviews on the potential effects of ocean acidification on microbial plankton have recently been published (Liu et al. 2010 Joint et al. 2011) . In a recent perspective paper, Joint et al.
