Abstract
- Biomass productivity and growth kinetics for microalgae grown on sodium bicarbonate and diammonium phosphate were investigated. Different carbon and nitrogen ratios have shown different growth rates and biomass productivity and C:N ratio 50:10 as mg L −1 has shown the best production than all. For effective lipids extraction from biomass thermolysis and sonolysis were carried out from wet biomass. Sonolysis at 2.3 W intensity for 5 min has released 8.58 mg at neutral pH. More quantity of lipids was extracted when extraction was made at pH 4 and 10 which resulted 9 mg and 9.28 mg lipids respectively. Thermal treatment at 100 °C for 10 min has released 12.82 mg lipid at neutral pH. In the same thermolysis at pH 4 and 10 more quantity of lipids was extracted which were 15.16 mg and 14.81 mg respectively. Finally transesterified lipids were analyzed through GC–MS for FAME composition analysis. [ABSTRACT FROM AUTHOR]
