A novel approach to the intensification of renewable and sustainable production of

ethanol from microalgal biomass was investigated using periodic ultrasonication. The effect of

utilizing ultrasonic pulsing during ethanol production through fermentation of spent biomass of

Synechocystis PCC6803 strain NAV001 was analysed using Saccharomyces cerevisiae with an

ultrasonic frequency of 20 kHz. Ultrasonic treatment resulted in enhancement of ethanol yields.

The ethanol yield was found to be higher along with increased cell concentration with the effect

of ultrasonication at 30°C, 15 % of power input (97.5 W) and 10 min pulse time. The growth and

ethanol production kinetics were determined using modified Gomperz equation. The specific

growth rate and the specific ethanol production rate were found to be 0.052 h-1 and 0.061 h-1

respectively, with the effect of ultrasonication.
