Abstract
Biomass is the most abundant renewable resource in the world and has potential to
use as alternative materials to fossil resources for production of chemicals and fuels.
For the effective conversion from biomass to biofuels or other chemicals, it requires
high efficient hydrolysis of cellulose to glucose or fermentable sugars. In this study,
lignocellulosic biomass, rice straw, rice husk, and water hyacinth were pretreated with
different chemicals, or pretreated with microwave heating, or with combination of
chemicals and microwave heating. Pretreated biomass was saccharified by using
commercial cellulase enzymes and released sugar contents were measured. The
combination of two pretreatment methods exhibited a synergy effect with 71.77% of
the enzymatic sugar conversion. To study the possibility to utilize sugars from
saccharified biomass, the de novo biosynthesis of fatty acid ethyl esters (FAEEs) in
Acinetobacter spp were observed. The key biochemical reaction is the esterification
between fatty acyl Co-A and ethanol using diacylglycerol acyltransferase (DGAT).
The highest FAEE production up to 1,040±51 mg/l was found in A.baylyi culture that
use biomass hydrolysate as a sole carbon source.
