Synthesis and characterization of Salicornia bigelovii and Salicornia brachiata halophytic plants oil extracted by supercritical CO2 modified with ethanol for biodiesel production via enzymatic transesterification reaction using immobilized Candida antarctica lipase catalyst in tert-butyl alcohol (TBA) solvent
A renewable clean energy is sine qua non for mitigation of toxic and greenhouse gas emissions, preservation of natural ecosystem, biodiversity and its sustainability. Hence, this research work focuses on the evaluation of biofuel potential characteristics of Salicornia plant’s oil (halophytes) that...

A renewable clean energy is sine qua non for mitigation of toxic and greenhouse gas emissions, preservation of natural ecosystem, biodiversity and its sustainability. Hence, this research work focuses on the evaluation of biofuel potential characteristics of Salicornia plant’s oil (halophytes) that grows in arid and salt water environment devoid of suitable edaphic and ecological factors that could support the growth and development of normal vegetable plants. Two species of the Salicornia plants were investigated. These are Salicornia bigelovii and Salicornia brachiata. A supercritical fluid extraction (SFE) process using carbon dioxide (CO2) modified with ethanol as extraction solvent yielded 32.14% of S. bigelovii oil and an oil yield of 26.58% S. brachiata.
