Pretreatment and hydrolysis processes on synechococcus Pcc 7002 cells for glucose production

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...
