Host-genotype-dependent cecal microbes are linked to breast muscle metabolites in Chinese chickens

open access: yesiScience, 2022
Summary: In chickens, the effect of host genetics on the gut microbiota is not fully understood, and the extent to which the heritable gut microbes affect chicken metabolism and physiology is still an open question.

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.

Thermal adaptation of decomposer communities in warming soils

open access: yesFrontiers in Microbiology, 2013
Temperature regulates the rate of biogeochemical cycles. One way it does so is through control of microbial metabolism. Warming effects on metabolism change with time as physiology adjusts to the new temperature.

Bayesian prediction of microbial oxygen requirement [v1; ref status: indexed, http://f1000r.es/1m6]

open access: yesF1000Research, 2013
Background: Prediction of the optimal habitat conditions for a given bacterium, based on genome sequence alone would be of value for scientific as well as industrial purposes. One example of such a habitat adaptation is the requirement for oxygen.

Physiological, metabolic and microbial responses to obesogenic cafeteria diet in rats: The impact of strain and sex

open access: yesThe Journal of Nutritional Biochemistry, 2023
Cafeteria (CAF) diet is known to accurately mimic the human Western diet in modern societies, thereby inducing severe obesity accompanied by drastic alterations on the gut microbiome in animal models. Notably, the dietary impact in the gut microbiota composition might be influenced by genetic factors, thus distinctively predisposing the host to ...
