Gene-Editing Tool Supercharges Bacteria for Better Livestock Feed

High-quality animal feed is a cornerstone of sustainable livestock farming, and for many animals, that means silage. This fermented fodder relies on the work of beneficial bacteria, primarily from the Lactobacillus family, which produce lactic acid to preserve nutrients. Traditionally, finding the most effective bacterial strains has been a slow and labour-intensive screening process.

Now, advances in synthetic biology are set to revolutionise this field. Scientists are harnessing the power of CRISPR-Cas9, a high-precision gene-editing tool, to directly engineer Lactobacillus strains. By making targeted changes to the bacteria’s genetic code, researchers can design customised microbes with enhanced traits for silage production.

This technique allows for the directed evolution of these tiny helpers, aiming to create next-generation microbial inoculants. The goal is to develop bacteria that are more efficient, adaptable to different crops, and eco-friendly, promoting better animal health and more resource-efficient agriculture.
