In the ocean, animal–microbial relationships were historically explored in single host–symbiont systems. However, new explorations into the diversity of microorganisms associating with diverse marine animal hosts is moving the field into studies that address interactions between the animal host and a more multi-member microbiome.
[89] [90] Studies have shown high protist diversity exists in oceans, deep sea-vents and river sediments, suggesting a large number of eukaryotic microbial communities have yet to be discovered. [ 91 ] [ 92 ] There has been little research on mixotrophic protists, but recent studies in marine environments found mixotrophic protests contribute a ...
Microbial biogeography is a subset of biogeography, a field that concerns the distribution of organisms across space and time. [1] Although biogeography traditionally focused on plants and larger animals, recent studies have broadened this field to include distribution patterns of microorganisms .
The work of Pasteur and Koch did not accurately reflect the true diversity of the microbial world because of their exclusive focus on microorganisms having direct medical relevance. It was not until the work of Martinus Beijerinck and Sergei Winogradsky late in the nineteenth century that the true breadth of microbiology was revealed. [23]
At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem. This low-abundance high-diversity group is the rare biosphere. Using this method, Sogin et al.’s study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa. [11]
Following present classification, there are a little less than 9,300 known species of prokaryotes, which includes bacteria and archaea; [185] but attempts to estimate the true number of bacterial diversity have ranged from 10 7 to 10 9 total species—and even these diverse estimates may be off by many orders of magnitude.
They maintain fungus gardens as the colony's primary food source. While the fungus itself does not digest cellulose, a microbial community containing a diversity of bacteria is doing so. Analysis of the microbial population's genome revealed many genes with a role in cellulose digestion.
