The Ottoman Turks relied heavily on troops recruited from the Balkans and Anatolia, and to a lesser extent the Middle Eastern provinces. The Barbary States were nominally part of the Empire, but their Beys / Deys (however you want to call them) acted on their own. Though their contribution to the Ottoman navy was significant (the best Ottoman admirals were recruited from the Barbary states), I am not aware of their contributing any land troops ever. The campaign season would have been over before any troops reached the front.
The only time I know of for certain that Ottomans used African troops is the 1911 war with Italy, when the Italians invaded Libya. And those probably would have been Bedouin.
