WebApr 22, 2013 · Optical density provides biological conversion factors for biomass and cell count. There are additional considerations beyond ‘pigmentation’ that affect the ability to correlate optical density with biomass and cell concentrations. In general, anything which affects either light absorption or scattering is a potential candidate. WebThe energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density . A biofuel is a fuel produced from recently living organisms. Biofuels include bioethanol, an alcohol made by fermentation —often used as a gasoline ...
