               As a leading global cause of preventable blindness and mortality, vitamin A deficiency (VAD) is a serious health problem, particularly in developing regions. Oviita aims to equip these vulnerable regions with a sustainable and community-based solution to VAD. Our solution uses a food-safe strain of Yarrowia lipolytica modified to produce beta-carotene, a Vitamin A precursor. By engineering this yeast to produce cellulase, VAD communities can grow it as their own vitamin A supplement using readily-available plant matter as feedstock. To facilitate community integration, we designed bioreactor schematics based on locally-available resources, and made the yeast auxotrophic to ensure safe growth with no environmental risk. We also created a Vitamin A biosensor to improve VAD testing, and included an anthelmintic agent in the yeast to combat poor intestinal health, two contributing factors to VAD. Through these solutions, Oviita aims to be a sustainable and community-based adjunct to global efforts against VAD.

A MAJOR PROBLEM


VITAMIN A DEFICIENCY IS A LEADING CAUSE OF CHILDHOOD MORTALITY AND BLINDNESS.
WE'RE HERE TO CHANGE THAT.

OVIITA DESIGN


As a leading global cause of preventable blindness and mortality, vitamin A deficiency (VAD) is a serious health problem, particularly in developing regions. Oviita aims to equip these vulnerable regions with a sustainable and community-based solution to VAD. Our solution uses a food-safe strain of Yarrowia lipolytica modified to produce beta-carotene, a vitamin A precursor. By engineering this yeast to produce cellulase, VAD communities can grow it as their own vitamin A supplement using readily-available plant matter as feedstock. To facilitate community integration, we designed bioreactor schematics based on locally-available resources, and made the yeast auxotrophic to ensure safe growth with no environmental risk. We also created a vitamin A biosensor to improve VAD testing, and included an anthelmintic agent in the yeast to combat poor intestinal health, two contributing factors to VAD. Through these solutions, Oviita aims to be a sustainable and community-based adjunct to global efforts against VAD. Check out our description page and our project presentation video to learn more about Oviita.

Project Components

Human Practices

We conducted in-depth interviews with nutrition experts and future users of our products

Engineering

We engineered the yeast strain Yarrowia liplytica to produce exactly what we needed for Oviita

Modelling

Computer modelling informed experimental design through every step

Proposed Implementation

The implementation of Oviita was thought through from start to finish

Parts

Several parts were added to the iGEM registry

Hardware

Our Bioreactor and Diagnostic Tool are integral to the implementation of Oviita

Software

We created an array of software models and tools to assist us in creating Oviita
