Calculation of Biodiesel Fuel Characteristics Based on the Fatty Acid Composition of the Lipids of Some Biotechnologically Important Microorganisms

详细

The interdependences between the structure of fatty acid and biofuel characteristics obtained from these fatty acids were briefly reviewed. The fatty acid compositions of the lipids of yeasts and phototrophic microorganisms were analyzed. The main parameters of the biodiesel (iodine value, cetane number, and kinematic viscosity) that can be made from the lipids of these microorganisms were calculated based on the data and compared to the current standards. The lipids of the yeast Rhodosporidium toruloides VKPM Y-3349 were shown to be the most suitable for biofuel production due to the composition and content of fatty acid. The possibilities of a decrease in the prime cost of microbial lipids (along with plant oils) that would make them competitive raw material for biofuel production were considered.
