High-pressure anaerobic digestion is an appealing concept since it can upgrade biogas directly within the reactor. However, the decline of pH caused by the dissolution of CO2 is the main barrier that prevents a good operating high-pressure anaerobic digestion process. Therefore, in this study, a high-pressure …

Organic farming is increasingly promoted as a means to reduce the environmental impact of artificial fertilizers, pesticides, herbicides, and antibiotics in conventional dairy systems. These factors potentially affect the microbial communities of the production stages (soil, silage, dung, and milk) of …

Decomposition is an ecosystem process, mainly important in the carbon and nitrogen cycles. When looking at what drives decomposition, there are three major drivers. These are plant litter quality, microbes and soil animals (detritivores). A large problem in understanding the decomposition process is …

Corals harbor complex and diverse microbial communities that strongly impact host ftness and resistance to diseases, but these microbes themselves can be infuenced by stresses, like those caused by the presence of macroscopic symbionts. In addition to directly infuencing the host, symbionts may transmit …

Introduction: This prospective study aimed to study the composition and structure of the vaginal microbiota prior to Chlamydia trachomatis infection. Methods: A nested case-control study was performed in 122 women, half of which acquired C. trachomatis within a year after their first visit. At the first …

Climate change is a major contributor to the range shifts of several organisms such as plant species. A range is the geographical area where a species can be found and it is possible for plant species to undergo a range shift while still being present in their original one. These plants are called range-expanders. …

Accumulating evidence dismisses the idea that bacteria are solitary bugs, living a completely independent existence. Instead, this definition is being replaced by the notion that bacteria are intimately communicating organisms holding tight relations to one another. One such process through which this …

Next-generation sequencing technology allows culture- independent analysis of species and genes present in a complex microbial community. Such metagenomics may overcome the inability to culture microbes in isolation. Microbial communities of interest are for example responsible for making biogas. Many …
