Abstract
A Study on the Production of Bioethanol from Portieria hornemannii Seaweed
Author(s): Annam Renita A, Utharalakshmi NBioethanol production was investigated in red algae Portieria hornemannii which belongs to the family Rhizophyllidaceae. Saccharomyces cerevisiae was cultured on Potato Dextrose Agar (PDA) media that had been sterilized at a temperature of 121°C and at a pressure of 1 atm for 15 min. It was incubated at 30°C for 3 days. Microbes on PDA media as culture stock was regenerated on the Yeast Extract Peptone Dextrose (YPD) media at 30°C for 24 h before mixing with hydrolysate. Reducing sugar was determined by 3,5-dinitrosalicylic acid (DNS) method. The seaweed hydrolysate from 60 g of seaweed gel (15 g of seaweed) yielded alcohol maximum in fermentate using S. cerevisiae as fermentation agent. Fermentation to produce alcohol was carried around 36-168 h. Bread yeast S. cerevisiae was found suitable for the bioethanol fermentation of seaweed hydrolysate, and gave an alcohol content of fermentate after 20-40 h of fermentation at room temperature.
