Countries across the globe have considered and directed state
policies toward the increased and utilization of biomass for meeting
their future energy demands in order to meet carbon dioxide
reduction targets as specified in the Kyoto Protocol as well as to
decrease reliance and dependence on the supply of fossil fuels
(Sarkar et al., 2012). Bioethanol has been receiving widespread
interest at the international, national and regional levels. The
global market for bioethanol has entered a phase of rapid, transitional
growth (Guragain et al., 2011). Lignocellulosics are processed
for bioethanol production through three major operations: pretreatment
for delignification is necessary to liberate cellulose
and hemicellulose before hydrolysis; hydrolysis of cellulose and
hemicellulose to produce fermentable sugars and fermentation of
reducing sugars (Singh and Bishnoi, 2012). Among various types
of lignocellulosic substances water hyacinth (Eichhornia crassipes)
is a potential resource available in many tropical regions of the
world. It is considered as a noxious weed in many parts of the
world as it grows very fast and depletes nutrient and oxygen rapidly
from water bodies, adversely affecting flora and fauna. Moreover,
due to high evapotranspiration it adds to water crisis all over
the places where it grows (Ganguly et al., 2012). Water hyacinth
grows extremely rapidly and produces almost 2 tons of biomass
