Biorefinery concept has becomes one of the great ideas to produce
multiple products from biomass especially microalgae as the
biofuel feedstock according to Cuellar Bermudez et al. (2015) but
information on this area is scarce (Cherubini, 2010). Prior to this,
more insight into these conversions from biomass is essential to
manage efficient operation like petroleum refinery (Pires et al.,
2012). As such, lipid extracted from microalgae is potential toproduce biodiesel through transesterification (Chen et al., 2012).
While the extracted biomass containing carbohydrate and protein,
could be valuable components to produce bioethanol and fertilizer,
