Previously, the main technique for studying the canine GI tract microbial community structure has been the cultivation of bacteria from intestinal contents [ 12, 14].
The study of microbial community structure has long centred around the debate between the hypothesis that 'everything is everywhere' (Bass Becking 1934), and the alternative that dispersal limitation influences microbial community structure (O'Malley 2007).
The effect of soil pH on specific microorganisms, soil microbial biomass, microbial activity and, more recently, on microbial community structure have been already investigated Pietri and Brookes (2008).
Terminal-restriction fragment length polymorphism estimates of microbial community structure have been found to be generally robust and concur with alternative approaches such as 454 pyrosequencing in documenting microbial community differences (Pilloni et al. 2012).
With regular shape, smooth surface, and compact and strong microbial structure, AGS has the advantages of better settling property, lower consuming, higher biomass retention, and treatment efficiency than normal activated sludge [ 3, 4].
Preserved organic remains will be characterized not only by their molecular and elemental composition but also by isotopic signatures indicative of microbial metabolism, a chiral signature, or specific distributions of OM associated with a specific structure having a microbial morphology (e.g., Figs. 2d 2e and 4a 4d, 4h).
In this study, the methods for modeling spatially distributed microbial communities with changing genetic structure have been presented along with the HEC 1D-3D software package.
The microbial community of the anodic biofilm had a similar microbial structure to the planktonic culture, but it was different to the cathodic biofilm.
Conversely, large population surveys relating microbial structure to function (transcripts and proteins) have also not yet been performed and will establish an important baseline, building on references such as the HMP and MetaHIT.
Granules cultivated at different initial sludge loading rates had different morphologies and microbial structure.
