As the global push for sustainable biofuels intensifies, lignocellulosic biomass has emerged as a prime candidate for biofuels and biochemicals owing to its abundance and renewability. This biomass, derived from plant materials, holds great promise as a feedstock for biofuel production. However, the pretreatment process required to break down lignocellulose often yields toxic byproducts like lignin-derived phenolic compounds and furanyl aldehydes.

News about biofuels sometimes mentions used cooking oil as a feedstock, but if these substances contain animal fat, they can solidify in colder temperatures. This happens because, chemically, the fatty acids of these and many other saturated fats have long carbon chains with single bonds. Enter the Euglena.
