摘要：Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic
materials, is one of the alternative energy resources, which is both
renewable and environmentally friendly. Although, the priority in global future
ethanol production is put on lignocellulosic processing, which is considered as
one of the most promising second-generation biofuel technologies, the utilizetion
of lignocellulosic material for fuel ethanol is still under improvement. Sugar-
based (molasses, sugar cane, sugar beet) and starch-based (corn, wheat,
triticale, potato, rice, etc.) feedstock are still currently predominant at the industrial
level and they are, so far, economically favorable compared to lingocelluloses.
Currently, approx. 80 % of total world ethanol production is obtained
from the fermentation of simple sugars by yeast. In Serbia, one of the
most suitable and available agricultural raw material for the industrial ethanol
production are cereals such as corn, wheat and triticale. In addition, surpluses
of this feedstock are being produced in our country constantly. In this paper, a
brief review of the state of the art in bioethanol production and biomass availability
is given, pointing out the progress possibilities on starch-based production.
The progress possibilities are discussed in the domain of feedstock
choice and pretreatment, optimization of fermentation, process integration and
utilization of the process byproducts.
