Microbial diversity and the “lower-limit” problem of biodiversity [PDF]

open access: yes, 2013
Science is now studying biodiversity on a massive scale. These studies are occurring not just at the scale of larger plants and animals, but also at the scale of minute entities such as bacteria and viruses. This expansion has led to the development of a

Responses of Fermentation Characteristics and Microbial Communities to Vitamin B12 Supplementation in In Vitro Ruminal Cultures

open access: yes, 2022
Vitamin B12, an important cofactor involved in propionate formation, is synthesized exclusively by bacteria and archaebacteria. Humans need to intake vitamin B12 through food, and dairy products are generally the best source of vitamin B12.

Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli

open access: yeseLife, 2017
While specific mutations allow organisms to adapt to stressful environments, most changes in an organism's DNA negatively impact fitness. The mutation rate is therefore strictly regulated and often considered a slowly-evolving parameter.

Structural and functional shifts in the microbial community of a heavy metal-contaminated soil exposed to short-term changes in air temperature, soil moisture and UV radiation [PDF]

open access: yes
The interplay between metal contamination and climate change may exacerbate the negative impact on the soil microbiome and, consequently, on soil health and ecosystem services.
