Title: The Innovative Contributions of Paul Grenier in Photobiological Research

Introduction

Paul Grenier, an accomplished inventor based in Québec, Canada, has made significant strides in the field of photobiology through his inventive solutions. With a total of six patents to his name, his work particularly focuses on enhancing methods for cultivating microalgae, showcasing his commitment to innovation in sustainable practices.

Latest Patents

Among his latest patents, Grenier has developed a V-shaped light distributor system. This sun-tracking light distributor is designed for photosynthetic cultures grown in aqueous solutions. The system comprises two transparent light distribution walls that create an elongated V-shaped channel. This design allows the structure to receive sunlight while partially submerged in the culture medium. The innovative aspect of this invention is its offset pivot axis, which enables the distributor to track the sun's altitude by altering the level of the aqueous liquid.

In addition to the light distributor, Grenier has created a method and system for the culture of microalgae. This method involves forming a consortium of at least two different species of microalgae and culturing them under controlled illumination in a bioreactor without the need for sterile conditions. The process not only promotes flocculation and settling of the microalgae but also allows for the modulation of their protein, carbohydrate, and fat content by adjusting culture conditions.
