- Recently, the potential use of microalgae as a source of biomass for fuel production has been focused because microalgae have advantages as a feedstock for energy production; they can be cultivated easily and are not considered to be human food sources. In this study, the anaerobic digestion (AD) process using microalgae as a substrate was investigated to see the possibility of methane production. Microalgae should be pretreated before adding into AD process in order to improve the biodegradability of organic materials. Herein, thermal, chemical, ultrasonic, and combined pretreatments were examined to find the optimum condition of pretreatments. The result showed that thermal, alkali, ultrasonic pretreatment were relatively effective, and their combinations were more effective than individual pretreatment in terms of cell lysis activity. Vial tests were performed by two combined (alkali/ultrasonic, ultrasonic/thermal) and two individual (thermal, ultrasonic) pretreated biomass of Dunaliella sp., and two mesophilic sludges obtained from municipal wastewater treatment plant (WTPSL) and local brewing company (BRSL) were used for inoculum sources. Pretreated biomass was spiked two times into vials containing anaerobic medium and inoculum sources, and methane production was measured up to 60 days. Consequently, as a control 0.752 and 0.198 L CH4/g TCOD were generated from WTPSL and BRSL itself, respectively. Vial containing pretreated microalgae produced 0.7–.2 times higher methane yields than negative control. Results also indicated that vial with combined pretreated microalgae extracted more methane gas compared to vial with un-pretreated microalgae. Therefore, it was demonstrated that microalgae have a potential to be a substrate in AD, and pretreatment have a positive effect on extracting more methane gas in AD.
