Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Discovery of a new subgroup of sulfur dioxygenases and characterization of sulfur dioxygenases in the sulfur metabolic network of Acidithiobacillus caldus.

PLoS ONE, 2017
Acidithiobacillus caldus is a chemolithoautotrophic sulfur-oxidizing bacterium that is widely used for bioleaching processes. Acidithiobacillus spp. are suggested to contain sulfur dioxygenases (SDOs) that facilitate sulfur oxidation.
