A chemolithotrophic bacterium, Serratia sp. ISTD04, enriched in the chemostat in presence of sodium bicarbonate as sole carbon source was evaluated for potential of carbon dioxide (CO2) sequestration and biofuel production CO2 sequestration efficiency of the bacterium was determined by enzymic activity of carbonic anhydrase and ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Further, Western blot anal. confirmed presence of RuBisCO. The bacterium produced 0.487 and 0.647 mg mg-1 per unit cell dry weight of hydrocarbons and lipids resp. The hydrocarbons were within the range of C13-C24 making it equivalent to light oil. GC-MS anal. of lipids produced by the bacterium indicated presence of C15-C20 organic compounds that made it potential source of biodiesel after transesterification. GC-MS, FTIR and NMR spectroscopic characterization of the fatty acid Me esters revealed the presence of 55% and 45% of unsaturated and saturated organic compounds resp., thus making it a balanced biodiesel composition This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Quality Control of Methyl nonadecanoate).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Quality Control of Methyl nonadecanoate
