Certain microalgae have been known to use light and
various carbon sources to produce carbohydrates, mainly
in the form of starch. This is one of the pertinent feedstocks
replacing agricultural products for the production of
bioethanol by yeast. This study focuses upon dilute acid
hydrothermal pretreatments at low cost and high efficiency to
compete with current methods, and employs Chlamydomonas
reinhardtii UTEX 90 as the feedstock. With dry cells of
5% (w/v), the algal biomass was pretreated with sulfuric
acid (1-5%) under temperatures from 100 to 120oC, from
15 to 120 min. As a result, the glucose release from the
biomass was maximum at 58% (w/w) after pretreatment
with 3% sulfuric acid at 110oC for 30 min. This method
enabled not only starch, but also the hydrolysis of other
oligosaccharides in the algal cell in high efficiency. Arrheniustype
of model equation enabled extrapolation of some yields
of glucose beyond this range. The pretreated slurry was
fermented by yeast, Saccharomyces cerevisiae S288C,
resulting in an ethanol yield of 29.2% from algal biomass.
This study suggests that the pretreated algal biomass is a
suitable feedstock for ethanol production and can have a
positive impact on large-scale applied systems.
