00:00The project we're involved in being funded by the Gates Foundation is all about producing cheap
00:05omega-3 oils for pregnant women in developing countries. At the moment the cost is prohibitive
00:11because the feedstocks that you need to produce omega-3s are expensive and getting omega-3s from
00:19the ocean is also not only economically expensive but it's unsustainable. So we can grow omega-3s
00:26in a lab but it's not cheap. So what we're trying to do is reduce the cost by using waste
00:31products to grow the organisms that make the omega-3s for us and those waste products are
00:36coming from agriculture. We're working here on the trostochitrids, we're looking at alternative
00:40sugars that we can potentially derive from agricultural residues, straws, any sort of plant material
00:49that may bring down the cost of our fermentation process.
00:56So when we're working here now, we're working with social engineering, we're working with
