Biomass in my research is plant and tree which is constituent of cellulose(50%), hemicellulose(xylan)(25%) and lignin(25%).
Cellulose is hydrolyzed to glucose by cellulase.
Xylan is hydrolyzed to xylose by xylanase.
Lignin is degrade by laccase.

Yeast produce ethanol from glucose and xylose as nutrient source.
Ethanol is alternative resources to petroleum.

Toyota produce lactic acid by yeast from glucose.
Dupon and Genencore produce 1.3 propanediol by bacteria from glucose.
Cannon challenge to produce hydroxyalkanoate by bacteria from glucose.
Lactic acid, 1.3 propanediol and hydroxyalkanoate is monomer of plastic materials.

Glucose is alternative resource to petroleum.
Starch is polysaccharide of α-1.4(75%) and α-1.6(25%) linked glucose unit.
Starch is hydrolyzed to glucose by amylase and pullulanase easily.
Now Bio-ethanol is produced from corn starch in USA.

Cellulose is polysaccharide of β-1.4 linked glucose unit.
It is very difficult to degrade cellulose by cellulase because your cotton T-shirt is strong.

Many scientists challenge this study for long time.
So I study cellulose by expensive book.
It is very difficult, but interesting for me.
Do you know glucose, cellulose and biomass?

Maybe Someiyoshino cherry blossom is most beautiful cherry in the world which Japanese produced in Edo era.
I hope that a man like Tadashi maekawa will change your mind.
It is not miracle, God lead you a well-suited life.
Please enjoy cocking.
