Effect of steam explosion pretreatment on treatment with Pleurotus ostreatus for the enzymatic hydrolysis of rice straw

Sulfite–formaldehyde pretreatment on rice straw for the improvement of enzymatic saccharification

“…A pretreatment combined with steam explosion (1.5 MPa for 1 min) and biological treatment (Pleurotus ostreatus for 36 days) was used to treated rice straw, the glucose yield were 86.8% of glucose in rice straw, with enzyme loading of 10 mg/g-substrate (Taniguchi et al, 2010). The SF pretreatment did not show a significant improvement in enzymatic hydrolysis sugar yield based on the existing method (diluted acid etc.).…”

Pre-treatment of Pinus radiata substrates by basidiomycetes fungi to enhance enzymatic hydrolysis

“…Glucose released after enzymatic hydrolysis was measured by YSI-2700D glucose analyser thermo-chemical treatment of P. radiata pulp is not toxic to fungi tested here and greater enzymatic digestibility suggests that the initial depolymerisation by fungal pre-treatment promoted subsequent enzymatic step. Taniguchi et al (2010) have also found that steam exploded rice straw treated with P. ostreatus for 36-48 days resulted in better enzymatic digestibility compared to the rice straw which had not been steam exploded but had been treated with fungi. In another study biological pre-treatment using E. taxodii in combination with post thermo-chemical treatment of corn straw, gave a higher yield of sugar compared to only thermo-chemical treatment (Yu et al 2010).…”

“…However, there is only one report on thermo-chemical treatment before fungal treatment, where rice husk was used as a substrate (Taniguchi et al 2010). To our knowledge, this is the first report on the use of steamexploded wood (SEW); a thermo-chemically treated Pinus radiata softwood pulp as a substrate for fungal treatment.…”

Advances in consolidated bioprocessing systems for bioethanol and butanol production from biomass: a comprehensive review

“…Utilization of these methods resulted in enhanced efficiency of sugar production, decreased formation of inhibitors and finally shortened process time. These combined pretreatment strategies include combination of alkaline and dilute acid pretreatments (Lu et al, 2009), alkaline and ionic liquid pretreatments (Nguyen et al, 2010), dilute acid and steam explosion pretreatments , supercritical CO2 and steam explosion pretreatments (Alinia et al, 2010), organosolv and biological pretreatments (Monrroy et al, 2010), biological and dilute acid pretreatments (Zhang et al, 2007 a,b), biological and steam explosion pretreatments (Taniguchi et al, 2010), microwave-assisted alkali pretreatment (Zhu et al, 2006), microwave-assisted dilute acid pretreatments (Chen et al, Fig.1.
