Bioethanol production from algae Spirogyra peipingensis using Saccharomyces cerevisiae, Pichia kudriavzevii and Kluyveromyces thermotolerans

Abstract

Abstract Spirogyra peipingensis algae is a microscopic green algae which is one of an alternative raw material to producing bioethanol because it has a high carbohydrate about 64%. This study aims to discover the growth of various types of yeast in S. peipingensis algae medium in producing bioethanol. This study uses hydrolysis methods and fermentation methods. In this study, the hydrolysis method using α-amylase enzyme as much as 150 KNU/L. The type of yeast used was Saccharomyces cerevisiae, Pichia kudriavzevii and Kluyveromyces thermotolerans. The result shown that the optimal yeast growth in producing ethanol is S. cerevsisiae was 0,49 g ethanol/g sugar at 10 hours fermentation duration. Based in the result shown that S. peipingensis algae can be used as raw material for producing bioethanol by using Saccharomyces cerevisiae .
