Should I talk first about what the problem is (malnutrition in India), or will we talk about it somewhere else?

Access

An important problem we wanted to tackle with our product is the access Indian people have to sources of vitamins. Indeed, we researched what structures and programs already exist in India, and found that it was a major issue.
One of the most important governmental programs for vitamin supplementation is the Integrated Child Development Services (ICDS) program, which has existed in India since 1975. This program monitors the growth and development of children, and provides supplementary nutrition as well as education and primary health care for children under six and pregnant and lactating mothers. The program is implemented through a network of community-level anganwadi centers (AWC), which provides daily supplements both in the center as well as through take-home rations. Those supplements include doses of vitamin A and tablets of iron and folic acid, in order to prevent xerophtalmia - which can lead to blindness - and anaemia.
However, the National Family Health Survey (NFHS-3) held in 2005-2006 in India reports that only 28% of children received those supplements and health care even though 4/5 of children under six lived in a region covered by an anganwadi center. In the 6 months preceding the survey, only 1/4 of the children between 12-35 months were given vitamin A supplements - and in 9 Indian states, this number falls to less than 20%. The access to ICDS has been improved in recent years, however, although access is still far from being universal (2). According to a national survey held in 2013-14, 46% of children aged 6-59 months had received doses vitamin A.
As for folic acid, the 2013-14 survey reports only 14% of children aged 6-59 months having received iron and folic acid supplements.

Though the program holds great promise and has implemented more than a million anganwadi centers, it is clear that people’s access to them is still very limited. People have to walk to the nearest center everyday if they want to receive the supplements, which is not convenient especially in rural areas.
This observation held a major role in our design of a product that can be grown at home, in every village or household. A culture of microorganisms doesn’t require an expensive infrastructure; in fact, most Indian families have already been growing microbial cultures that are several generations old by using a part of their daily yogurt as a starter for the fermentation of the next day’s yogurt. As we have shown (Célia’s part), a microbial culture can be grown on or in a very simple media like potato juice.
We believe that a culture of yeast and bacteria that can be grown at home and supplements fermented foods with vitamins could reach far more people than the anganwadicenters: those cultures would only need to be distributed once, which would not be very costly as the packages can be made to be very small and light and one culture would act as a starter culture for many more. In this way, the culture would be maintained in the home, without the need for people to travel long distances to have access to nutritional supplements.

Our product is also more accessible in that it doesn't have the same geographic and climate constraints as cultures of rice or other crops. Contrary to Golden Rice, the rice developed by the Swiss Federal Institute of Technology and the University of Freiburg that biosynthesizes beta-carotene and can only be grown in environments with very high water availability, a microbial culture can be grown anywhere. Even though this summer we mostly focused on microbial cultures of fermented dishes composed of rice, microbes are used to ferment any kind of cereals as well as other foods. So our product can be adapted to a very wide range of fermented dishes, and could also be used by people who don’t eat rice.

Why idli?

Idli (or idly) is a small steamed cake made with fermented rice and black lentils (called urad dal or dal). It is a very popular breakfast food across India, mostly in the south, and is often eaten with chutney.
We wanted our product to truly fit the traditions and tastes of the people we were targeting, and idli appeared to be the ideal dish. It is a very popular staple of the Indian diet, along with the crepe-like dosa, which is made of a similar but less coarse batter. Its two ingredients (rice and dal) are very cheap and widely available resources, and idli is commonly eaten by people who lack other types of food and who suffer from vitamin deficiencies. There is even a program that distributes free rice to the poorest populations in the country, the Public Distribution System (PDS); and in the city of Chennai and its suburbs, canteens called Amma Unavagam sell idli and other foods for very low prices (Rs1 for 1 idli).

Besides its popularity and easy accessibility, the most interesting property of idli is that it is fermented. To cook idli, people soak rice and dal separately, then grind and mix them together, then let the batter ferment overnight. In the hot Indian climate, the batter ferments quickly and its volume can triple overnight.
Many studies have been made on the microbiome of idli batter. Though the strains found in idli can be highly variable from one study to another, probably because the microbiome varies from different regions, we found that Lactococcus lactis and Lactobacillus plantarum are among the most common fermentative bacteria found in idli batter, while in the yeast population, Saccharomyces cerevisiae was always present. ADD SOURCES Since we wanted our product to disrupt as little as possible the idli's taste, we chose these organisms for production of the different vitamins and to improve iron availability, instead of adding new micro-organisms that weren’t already present in the idli batter that may have influenced the microbiome in an unpredictable manner. Many people who reviewed our project said that taste was of high importance, and would prefer that we modified microbes already present in the idli rather than add new ones.
+ should we talk about the advantages of fermented foods?

Design

By talking about your design work on this page, there is one medal criterion that you can attempt to meet, and one award that you can apply for. If your team is going for a gold medal by building a functional prototype, you should tell us what you did on this page. If you are going for the Applied Design award, you should also complete this page and tell us what you did.

Note

In order to be considered for the Best Applied Design award and/or the functional prototype gold medal criterion, you must fill out this page.

This is a prize for the team that has developed a synthetic biology product to solve a real world problem in the most elegant way. The students will have considered how well the product addresses the problem versus other potential solutions, how the product integrates or disrupts other products and processes, and how its lifecycle can more broadly impact our lives and environments in positive and negative ways.

If you are working on art and design as your main project, please join the art and design track. If you are integrating art and design into the core of your main project, please apply for the award by completing this page.
