Among the enzymes that play a critical role in optimizing animal nutrition, xylanase is widely acknowledged for its ability to break down complex polysaccharides in plant-based feed ingredients, improving nutrient utilization and overall animal performance. However, in recent decades, despite advances in production, processing technologies, and utilization of by-products, xylanase enzyme technology has lagged behind, especially in flexibility required for modern diet formulation.

This journal provides insight as to why Bacillus subtilis is such a remarkably diverse bacterial species – capable of growth within diverse environments including the gastrointestinal tracts of animals. Though dated, the article shows that this highly diverse bacteria has always been widely used for animal husbandry and other applications.
