Перспективи Виробництва Біобутанолу З Рештків Біомаси Мікроводоростей Після Ліпідної Екстракції

“…Biobutanol is a renewable biofuel chemically similar to gasoline but produced from biomass rather than fossil fuels. It is typically produced through fermentation, usually using strains of bacteria from the class Clostridia, which convert sugars derived from biomass into butanol via acetone-butanol-ethanol (ABE) fermentation [1].…”

Introduction.Biobutanol is a renewable biofuel chemically similar to gasoline but produced from biomass rather than fossil fuels. It is typically produced through fermentation, usually using strains of bacteria from the class Clostridia, which convert sugars derived from biomass into butanol via acetone-butanol-ethanol (ABE) fermentation [1].Biobutanol can become a severe competitor to other types of biofuels. For instance, one advantage of biobutanol over ethanol is its higher energy density, which means it contains more energy per unit volume.

“…In addition, biobutanol has a lower vapour pressure than ethanol, which can reduce evaporative emissions and make it easier to blend with gasoline.Biobutanol can also be used in existing gasoline engines without significant modifications. It can be blended with gasoline at higher concentrations than ethanol without causing engine damage or performance issues [1]. Therefore, it has the potential to be used as a "drop-in" replacement for gasoline, which would make it easier to integrate into existing fuel infrastructure and vehicle fleets.Discussion.…”

Several feedstocks can be used for biobutanol production, including agricultural residues, energy crops, lignocellulosic materials, food waste, and algae [1]. The choice of feedstock depends on various factors, including availability, cost, and sustainability.The production of first-generation biobutanol is largely made possible by the fermentation of primarily hexose sugars, which is a reasonably straightforward process.…”
