| description | Microalgae are potential alternative source for ren
ewable energy such as bioethanol. To
produce bioethanol pretreatment methods such as son
ication and acid hydrolysis for
carbohydrate production are required. Pretreatment
is important to release the
carbohydrate from the microalgae cell wall as well
as to increase the production. These
processes were applied to
Synechococcus
PCC 7002, a type of cyanobacteria species.
The aim of this project was to release the glucose
from cyanobacteria cells prior to
bioethanol production. Three parameters were studie
d which were sonication time (15,
30 and 45 minutes), sulphuric acid concentration (1
%, 3%, 5% and 7% v/v) and
hydrolysis time (15 and 30 minutes). The response s
tudied was carbohydrate yield. The result showed that, most of the samples with 15 min utes of sonication gave higher carbohydrate content compared to 30 and 45 minutes. In contrast to that, highest concentration of sulphuric acid at 7% and longer hydrolysis duration at 30 minutes hydrolysis gave higher yield of carbohydrate. It was concluded that neither glucose nor sucrose yields from sonicated and hydrolyzed biomass. This could be due to insufficient of heat to break the glycosidic linkage between the oligosaccharide. |
