 Green algae can be used to produce bioethanol through a process that involves: 

 

Cultivation: Algae is grown in ponds or photobioreactors using sunlight. 

 

Harvesting: The algae mass is concentrated. 

 

Extraction: The starch is extracted from the algae cells using mechanical tools or enzymes. 

 

Fermentation: The hydrolyzed algae mass is fermented with yeast, such as Saccharomyces cerevisiae. 

 

Distillation: The bioethanol is separated through distillation. 

 

Here are some other things to consider when producing bioethanol from algae: 

 

Pretreatment

Mechanical pre-processing, such as drying, milling, and homogenization, can be used to prepare the algae for fermentation. 

 

Yeast strains

Engineered yeast strains can be used to improve bioethanol production. 

 

Fermentation methods

Simultaneous saccharification and fermentation (SSF) and simultaneous saccharification and co-fermentation (SSCF) can increase the yield of ethanol and reduce the time required for production. 

 

Algae growth

Algae can grow in saline or artificial seawater, as well as on non-agricultural land. 

 

Algae composition

Green seaweeds are rich in cellulose, which can be hydrolyzed and fermen

ted to produce bioethanol.
