1 · What it gives

Biodyes and microbial pigments offer a sustainable alternative to petrochemical-based colorants. The industry utilizes engineered microbes to produce high-value pigments at scale, targeting a $30 billion market while reducing water usage by up to 80% and eliminating toxic heavy metal mordants. Commercial volumes now exceed 500 tons annually across textile and food applications. This technology fundamentally changes textile dyeing and food coloring by replacing harsh chemical synthesis with biological production.

The key directions of biodyes and microbial pigments are:

  1. Textile Biodyes: Microbial indigo and other fabric dyes replacing synthetic variants.
  2. Food Colorants: Natural bio-pigments like phycocyanin for food and beverage applications.
  3. Cosmetic Pigments: Bio-based colorants for makeup and personal care, offering high purity.
  4. Industrial Coatings: Environmentally friendly pigments for paints and coatings.
