Several researchers have been reported bioethanol production
from certain species of algae, which produce high levels of carbohydrates
as reserve polymers. Owing to the presence of low lignin
and hemicelluloses content in algae in comparison to lignocellulosic
biomass, the algal biomass have been considered more suitable
for the bioethanol production (Chen et al., 2013). Recently,
attempts have been made (for the bioethanol production) through
the fermentation process using algae as the feedstocks to make it
as an alternative to conventional crops such as corn and soyabean
(Singh et al., 2011; Nguyen and Vu, 2012; Chaudhary et al., 2014).
A comparative study of algal biomass and terrestrial plants for the
production of bioethanol has been given in Table 3
