Acid enzymes are commonly used in various industries, particularly textiles, food, and bio-processing, due to their ability to function in low pH (acidic) environments. Here’s an overview of their uses:

In textile processing, acid enzymes are used mainly for bio-polishing and bio-scouring.

Bio-Polishing: Acid cellulases are often employed to remove microfibrils from the surface of cellulosic fabrics (like cotton), improving fabric softness, smoothness, and anti-pilling properties. The process works at low pH (around 4.5 to 5.5).

Bio-Scouring: This process uses acid enzymes to remove non-cellulosic impurities such as waxes, pectins, and oils from cotton fibers. It replaces harsh chemicals with enzymes to create a cleaner, softer fabric that absorbs dye better.
