Characterization and Integrated Process of Pretreatment and Enzymatic Hydrolysis of Corn Straw

Abstract The chemical pretreatment of biomass has been integrated with enzyme production through the recycling of aqueous fractions. Alkaline/$ H_{2} %$ O_{2} $ delignification of corn straw (CS) was performed to obtain a 75.1% w/w cellulose solid fraction and to dissolve 93.4 and 83.5%, of the orig...

520			\|a Abstract The chemical pretreatment of biomass has been integrated with enzyme production through the recycling of aqueous fractions. Alkaline/$ H_{2} %$ O_{2} $ delignification of corn straw (CS) was performed to obtain a 75.1% w/w cellulose solid fraction and to dissolve 93.4 and 83.5%, of the original lignin and hemicelluloses, respectively. Next, a Pleurotus cystidiosus native strain was left to grow for 120 h in the resulting liquid fraction. After filtering the cells, the liquid medium was used alone or combined with the commercial enzyme. To reduce chemical and water usage, the liquid fraction from pretreatment was recycled to perform another treatment; the pH, CS, and $ H_{2} %$ O_{2} $ were adjusted. A process integrated with P. cystidiosus was grown again and enzymatic hydrolysis was realized. Samples of every liquid fraction from the fungal growing medium were analyzed to determine the chemical oxygen demand (OCD), glucose (Glu), xylose (Xyl), and total reducing sugars (RS). Separately, to obtain valuable polymers from this integration process, solid hemicellulose and lignin were isolated from the remaining liquid fractions through pH variation. The composition of the samples was determined using scanning electron microscopy (SEM), optical stereoscopic microscopy and Fourier transform infrared spectroscopy (FT-IR) and was compared with commercial homologs. The maximum conversion of cellulose to glucose by the obtained liquid fraction of the fungal medium was 61.3 ± 0.9% of the theoretical conversion yield of the commercial enzyme. Similarly, the conversion of hemicelluloses to xylose was 69.5 ± 1.5%. Finally, in this work, an integrated platform for cellulose, hemicellulose, lignin, enzymatic extract and sugars production, which also significantly reduces water consumption, was proposed.

Alkaline/$ H_{2} %$ O_{2} $ delignification of corn straw (CS) was performed to obtain a 75.1% w/w cellulose solid fraction and to dissolve 93.4 and 83.5%, of the original lignin and hemicelluloses, respectively. Next, a Pleurotus cystidiosus native strain was left to grow for 120 h in the resulting liquid fraction. After filtering the cells, the liquid medium was used alone or combined with the commercial enzyme. To reduce chemical and water usage, the liquid fraction from pretreatment was recycled to perform another treatment; the pH, CS, and $ H_{2} %$ O_{2} $ were adjusted. A process integrated with P. cystidiosus was grown again and enzymatic hydrolysis was realized. Samples of every liquid fraction from the fungal growing medium were analyzed to determine the chemical oxygen demand (OCD), glucose (Glu), xylose (Xyl), and total reducing sugars (RS). Separately, to obtain valuable polymers from this integration process, solid hemicellulose and lignin were isolated from the remaining liquid fractions through pH variation. The composition of the samples was determined using scanning electron microscopy (SEM), optical stereoscopic microscopy and Fourier transform infrared spectroscopy (FT-IR) and was compared with commercial homologs. The maximum conversion of cellulose to glucose by the obtained liquid fraction of the fungal medium was 61.3 ± 0.9% of the theoretical conversion yield of the commercial enzyme. Similarly, the conversion of hemicelluloses to xylose was 69.5 ± 1.5%.

Alkaline/$ H_{2} %$ O_{2} $ delignification of corn straw (CS) was performed to obtain a 75.1% w/w cellulose solid fraction and to dissolve 93.4 and 83.5%, of the original lignin and hemicelluloses, respectively. Next, a Pleurotus cystidiosus native strain was left to grow for 120 h in the resulting liquid fraction. After filtering the cells, the liquid medium was used alone or combined with the commercial enzyme. To reduce chemical and water usage, the liquid fraction from pretreatment was recycled to perform another treatment; the pH, CS, and $ H_{2} %$ O_{2} $ were adjusted. A process integrated with P. cystidiosus was grown again and enzymatic hydrolysis was realized. Samples of every liquid fraction from the fungal growing medium were analyzed to determine the chemical oxygen demand (OCD), glucose (Glu), xylose (Xyl), and total reducing sugars (RS). Separately, to obtain valuable polymers from this integration process, solid hemicellulose and lignin were isolated from the remaining liquid fractions through pH variation. The composition of the samples was determined using scanning electron microscopy (SEM), optical stereoscopic microscopy and Fourier transform infrared spectroscopy (FT-IR) and was compared with commercial homologs. The maximum conversion of cellulose to glucose by the obtained liquid fraction of the fungal medium was 61.3 ± 0.9% of the theoretical conversion yield of the commercial enzyme. Similarly, the conversion of hemicelluloses to xylose was 69.5 ± 1.5%. Finally, in this work, an integrated platform for cellulose, hemicellulose, lignin, enzymatic extract and sugars production, which also significantly reduces water consumption, was proposed.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alkaline delignification</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cellulose</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hemicellulose</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Lignin</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Lignocellulosic biomass</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biorefinery</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Molina Guerrero, Carlos Eduardo</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gutierrez Ortega, Norma Leticia</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Leal Vaca, Julio Cesar</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Alvarez Vargas, Aurelio</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cano Canchola, Carmen</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Waste and biomass valorization</subfield><subfield code="d">[Dordrecht] : Springer Netherlands, 2010</subfield><subfield code="g">10(2018), 7 vom: 16.

abstract	Abstract The chemical pretreatment of biomass has been integrated with enzyme production through the recycling of aqueous fractions. Alkaline/$ H_{2} %$ O_{2} $ delignification of corn straw (CS) was performed to obtain a 75.1% w/w cellulose solid fraction and to dissolve 93.4 and 83.5%, of the original lignin and hemicelluloses, respectively. Next, a Pleurotus cystidiosus native strain was left to grow for 120 h in the resulting liquid fraction. After filtering the cells, the liquid medium was used alone or combined with the commercial enzyme. To reduce chemical and water usage, the liquid fraction from pretreatment was recycled to perform another treatment; the pH, CS, and $ H_{2} %$ O_{2} $ were adjusted. A process integrated with P. cystidiosus was grown again and enzymatic hydrolysis was realized. Samples of every liquid fraction from the fungal growing medium were analyzed to determine the chemical oxygen demand (OCD), glucose (Glu), xylose (Xyl), and total reducing sugars (RS). Separately, to obtain valuable polymers from this integration process, solid hemicellulose and lignin were isolated from the remaining liquid fractions through pH variation. The composition of the samples was determined using scanning electron microscopy (SEM), optical stereoscopic microscopy and Fourier transform infrared spectroscopy (FT-IR) and was compared with commercial homologs. The maximum conversion of cellulose to glucose by the obtained liquid fraction of the fungal medium was 61.3 ± 0.9% of the theoretical conversion yield of the commercial enzyme. Similarly, the conversion of hemicelluloses to xylose was 69.5 ± 1.5%. Finally, in this work, an integrated platform for cellulose, hemicellulose, lignin, enzymatic extract and sugars production, which also significantly reduces water consumption, was proposed. © Springer Science+Business Media B.V., part of Springer Nature 2018
