Enzymatic saccharification of agar waste from Gracilaria verrucosa and Gelidium latifolium for bioethanol production
Worldwide, 9600 t of agar is produced annually. Meanwhile, 60% of the waste produced from the agar industry yearly do not get treated. Our present study aims to study the enzymatic saccharification of solid agar waste produced from two of the most widely used agarophytes in the agar industry, Gracil...

| description | Worldwide, 9600 t of agar is produced annually. Meanwhile, 60% of the waste produced from the agar industry yearly do not get treated. Our present study aims to study the enzymatic saccharification of solid agar waste produced from two of the most widely used agarophytes in the agar industry,
Gracilaria verrucosa
and
Gelidium latifolium
.
Gracilaria
species are the most common raw material in the food grade agar industry, while
Gelidium
species are the most common raw material used for bacteriological and pharmaceutical purposes because of the high-quality agar that is produced from these species. Our results showed that waste generated from agar extraction still contained sugars which could be optimized by acid pretreatment and enzymatic saccharification.
Gracilaria verrucosa
resulted in a higher agar yield (35.15 ± 1.17%), but produced less agar waste (20.91 ± 0.43%) than
G. latifolium.
After sequential acid pretreatment and enzymatic saccharification of the agar waste, the agar waste hydrolysate of
G. latifolium
resulted in higher glucose, galactose, and ethanol production, and a higher ethanol yield (18.17 ± 0.75, 16.17 ± 2.07, and 10.83 ± 0.30 g L
−1
and 0.33 g g
−1
, respectively) than
G. verrucosa
. The results from our present study may be used to optimize biorefinery utilization of
G. verrucosa
and
G. latifolium
