The process is applied directly to a culture medium. It thus makes it possible to obtain a powder comprising at least one probiotic bacterium by using a "two-in-one" nutrient medium.

Avantages

  • Simplified and cheap process whose efficiency is similar to lyophilization.
  • This process limits contamination risk and cellular loss risk (2 steps instead of 4).
  • This process highly reduces energy cost which is liked to water removal step and allows a simplier solution.
  • This process can be used on industrial installations on a large scale.

Applications

  • Probiotics production intended for animal and human food
