Research program focused on the microbiological mechanisms underlying feed efficiency, enteric emissions, and nutrition in beef cattle. Posts are my own.
Excited to share our article on testing molecular mechanisms using a constructed #bioluminescent reporter. The fundamental knowledge gained from this work now underpins our research into developing beneficial microbes for #rumenhealth and #probiotics.

Application of the solvent effect on bioluminescent reporter bacteria as a real-time membrane toxicity assay
Bioluminescent bioreporters are widely used across various scientific disciplines due to the well-characterized bacterial bioluminescence mechanism. However, solvent-induced membrane perturbations may...
