Outline of a strategy for developing the inerme cactus in Tunisia

The inerme cactus has been planted for fodder purposes on several tens of thousands of hectares in central Tunisia. These plantings are largely the result of government encouragement, incentives and achievements. Studies on the development of this species worldwide have made it the "miracle" shrub. Its development in central Tunisia is an immediate obligation, given its total integration into all the region's production systems. A study of the biochemical composition of the various extracts from OFI snowshoes (powder or gel) and fruits showed the presence of high levels of secondary metabolites (total phenols, flavonoids and tannins). These extracts may therefore be effective in inhibiting the development of pathogenic microorganisms or the growth of certain plants. According to the DPPH method, they also have significant antioxidant activity. Our experiments have also shown that mucilage can be used as natural, biodegradable coagulants in water treatment, with a view to reducing the use of chemicals.
