Most of the crude glycerol produced globally is generated by biodiesel production, which
makes this byproduct an environmental responsibility of the biofuel industries. Among the
forms of this compound in use, microalgae cultivation is a promising alternative that may
generate a reduction in crude glycerol treatment costs via using it as an organic, carbon-rich
substrate in culture media. In this work, the influence of different concentrations of glycerol in
the culture medium, the composition of fatty acids and proteins in Spirulina sp. LEB 18 …
