Microbial diversity changed depending on the day of sacrifice in some parts of the digestive tract, especially in distal jejunum and cecum.
The microbial diversity and diversity changes of the sludge samples were ascertained by applying 16S rRNA gene cloning and terminal restriction fragment length polymorphism (TRFLP) analyses, respectively, and using sludge samples from the inoculum, throughout and at the conclusion of the bioreactor trial.
The study on microbial diversity and dynamic changes during MMF fermentation cannot only be conducive to elucidate the fermentation mechanism and to optimize the fermentation process but also has significant potential for controlling the fermentation of MMF.
A concurrent investigation of the microbial population of the same soil samples also showed microbial population composition varying more with soil depth than landscape position, and depth changes in microbial diversity occurred concomitantly with depth changes in organic matter chemistry.
Here we demonstrated that microbial diversity and composition changed both horizontally across the polygonal landscape and with depth into the permafrost layer.
This book provides an overview of our current understanding of paddy soil pollution, addressing topics such as the major types of pollutants in contaminated paddy soil ecosystems; factors affecting the fate of pollutants in paddy soil; biomonitoring approaches to assess the contaminated paddy soil; the impact of chemicals on soil microbial diversity; and climate change.
In Expedition 304 rock samples that were collected from 0.45 to 397.32 meters below seafloor (mbsf) the same two DGGE bands were observed in all samples; therefore, microbial diversity did not change with depth, or rock type.
Although collecting molecular data was beyond the scope of this study, examining the links between changes in plant diversity, changes in microbial community structure, and how these changes affect microbial functioning is a key direction for future research [10].
A number of studies have documented changes in microbial diversity due to fumigants and pesticides [46], [47], [48], although the majority of changes were short-term, with microbial populations generally returning to normal after a few weeks or months.
These efforts further our understanding of community composition changes over time and the environmental factors that may have the greatest influence on the observed changes in microbial diversity.
