Abstract:

© 2019 The aim of the presented research was application of optimized cultivation conditions for lipid production using the oleaginous microalga Chlorella pyrenoidosa Chick (IPPAS C2), followed by an assessment of the bioenergy potential of lipid-rich biomass and biomethane production. The optimization of cultivation parameters led to an increase in lipid production. The average and maximum lipid production for C. pyrenoidosa was 101 ± 22 mg.L −1 .D −1 and 126 mg.L −1 .D −1 , respectively. The average calorific value of the lipid rich-biomass was 27.56 ± 0.93 MJ.kg −1 . However, the recorded biomethane yield of 0.16 ± 0.006 m 3 .kg −1 VS, caused probably by low digestibility of C. pyrenoidosa and by short hydraulic retention time during anaerobic digestion, was interpreted as low. However, the high lipid content along with high calorific value indicated an increased bioenergy potential of microalgal biomass cultivated under the optimized cultivation parameters.
