In natura plants, which include its leaves, fruits and barks, do not allow the interaction of external microorganisms with their internal fundamental structures. The intact part of the plant contains Rhodotorula and Plantarém lactobacilli in its surface. When the plant is processed, the microorganism on the surface will have access to the protected composition including a number of  components transforming them  into bioactives. As example, Rhodotorula are capable of transforming carotenoids into retinol.

The secret and the challenge of biotechnology is to develop the correct stimulus for the production of the bioactive needed. Plantus developed an innovative biotechnological fermentative process to stimulate that production in oily products, obtaining unique products with functional bioactives and enzymes without using genetically modified organisms.
