Scientists have used high-resolution mass spectrometry to determine the composition of a biofuel obtained from the microalgae Spirulina platensis. The researchers studied two biofuel fractions obtained using a special algal mass treatment method. The researchers also proved that biofuel has little to do with oil in terms of its composition. However, it is similar to the “brilliant green” antiseptic commonly sold in Eastern Europe. The results of the study were published in the European Journal of Mass Spectrometry.
