This study demonst rated the feasibility of producing bioethanol
from microalgal biomass. The self-mad e enzyme mixture from
Pseudomona s sp. CL3 containing suitable amylase/cell ulase composition
could effectively hydrolyze C. vulgaris FSP-E biomass for subsequent
ethanol production via the SHF and SSF processes. Ethanol
production by the SHF process with dilute acid hydrolysi s (1%
H2SO4) of the microalgal biomass was more effective, producing
11.66 g L1 of ethanol within 12 h with a yield of 87.59% of the theoretical
one. The above mentioned bioethanol producing process
can be applied to large-scal e bioethanol production using carbohydrate-rich
microalgae as the feedstock.
