Influence of Thermal and Bacterial Pretreatment of Microalgae on Biogas Production in Mesophilic and Thermophilic Conditions
In order to accelerate anaerobic digestion we applied different types of pretreatments of microalgae. Following the obtained results, we can conclude that thermal pretreatment at 90 °C is the most effective method for increasing methane and biogas production under mesophilic conditions. Biogas production was increased by 16 % and methane production by 21 %. Biological pretreatment with bacterium P. xylanivorans Mz5T is the most effective method for increasing methane and biogas production under thermophilic conditions. Methane production was increased by 13 %. Combined (thermal- biological) pretreatment showed the strongest effect in thermophilic process. Biogas production was increased by 11 % and methane production by 12 %. Further research should be carried out to determine which pretreatments are the most economical for individual biogas plant and which algae species are the best for biofuel production, before we could transfer the research to higher scale.
