*1.1.5 Sweet sorghum*

Sweet sorghum (*Sorghum saccharatum*) is a valuable energy crop containing both starches and sugars. More than 17,000 types of sorghum are known to exist in world. Ethanol production of 3500 L ha<sup>−</sup><sup>1</sup> can be obtained from the fermentable sugars alone. An additional 1600–1900 L is derived from stalk fibers using SSF process. With hybrid strains, the yield may be increased 30% above present levels [17].

The adaptability to the majority of the world's agricultural regions, its resistance to draught, and its efficient utilization of nutrients make it as a viable raw material for ethanol production using SSF process [18].
