Biomass and lipid induction strategies in microalgae for biofuel production and other applications por Alishah Aratboni, Hossein, Rafiei, Nahid, García Granados, Raúl, Alemzadeh, Abbas, Morones Ramírez, José Rubén

“…There are different types of biofuels (categories and generations) that have been previously explored, but recently, the use of microalgae has been strongly considered for the production of biofuels since they present a series of advantages over other biofuel production sources: (a) they don’t need arable land to grow and therefore do not compete with food crops (like biofuels produced from corn, sugar cane and other plants) and; (b) they exhibit rapid biomass production containing high oil contents, at least 15 to 20 times higher than land based oleaginous crops. …”
