Table 3 Summary for the effects of moisture content on lignocellulose pretreatment

From: Impact of moisture content on instant catapult steam explosion pretreatment of sweet potato vine

Pretreatment

Biomass

Sugar yield

Advantage

Disadvantage

Refs.

Ionic liquid

Switchgrass

70%

Decrease the cost of ionic liquid pretreatment

The existence of water will hamper the efficiency of pretreatment

Shi et al. (2014a)

Grinding

Wheat straw, corn stover etc.

NA

NA

Result in additional energy requirement and higher final particle size

Barakat et al. (2015)

Supercritical CO2

Southern yellow pine

84.7%

The increase of initial moisture content will obtain higher final sugar yield

NA

Kim and Hong (2001)

Steam explosion

Corn stover

90%

Improve the sugar yield

Not benefit for the quickly heating of biomass during pretreatment

Sui and Chen (2015)

Ammonia fiber steam explosion

Corn stalk

80%

Increase of moisture content does not hamper the enzymatic hydrolysis of lignocellulose

Ditto

Moniruzzaman et al. (1997)

Steam explosion

Softwood

60–90%

Prompt the enzymatic hydrolysis and reduce the hydrolysis of hemicelluloses content

Ditto

Cullis et al. (2004)

Acid steam explosion

Corn stover

> 90%

(Xylose)

High soluble sugar yield

Ditto

Emmel et al. (2003)
