Most of the liquid laundry detergents are with living micro organisms that help to break down stains.

Many biological laundry detergents contain enzymes (proteases, lipases, amylases) derived from microorganisms that break down protein, fat, and starch-based stains. While the enzymes themselves are not 'living organisms' in the finished product, they are produced by living microorganisms (bacteria, fungi) and are the active cleaning agents.
