A company, Bioextracts Pty Ltd, was established to fund and commercialize our research. A process that we have developed for extracting proanthocyanidins has been licensed by Bioextracts to Merck Pharmaceuticals and is marketed as Bioxidin. Another product Phytobiotic is a cream used to combat wound infections. There are several other products in the development stage.
Several other small industrial companies supplied funds to investigate potential applications of plant extracts. In some cases products were patented.
We received funding against strong national competition of R2.2 million over a two year period to investigate the replacement of antibiotic feed additives in poultry feed for 2004/2005.
