Molecular-bred Coprinus cinereus monokaryotic strains with high lignin- and xylan-degrading activities were mixed-cultured at 27 degrees C in the liquid medium containing 0.5% (w/v) cut rice straw and 0.025% MnCl2. After 3 weeks, the culture supernatant was extensively treated with crude cellulase, showing the presence in it of 9.3% of the total cellulose of rice straw. When rice straw treated ...

Biobutanol produced by Clostridium spp. can be used as a biofuel and/or chemical feedstock. For cost-effective and sustainable production of biobutanol, an untapped biomass such as rice straw could be used as a substrate. Rice straw, which is composed of cellulose, hemicellulose, and lignin, is cheap and abundant. However, the utilization of rice straw is limited because butanol-producing clost...

Two in vitro experiments were conducted to evaluate the effect of methylcellulose (MC) on i) bacterial detachment from rice straw as well as ii) inhibition of bacterial attachment and fiber digestibility. To evaluate the effect of MC on fibrolytic bacterial detachment (Exp 1), in vitro bacterial cultures with 0.1% (w/v) MC solution were compared with cultures without MC after 8 h incubation. Th...

An in vitro experiment was conducted to evaluate the effect of methylcellulose on the attachment of major cellulolytic bacteria on rice straw and its digestibility. Rice straw was incubated with ruminal mixture with or without 0.1% methylcellulose (MC). The attachment of F. succinogenes, R. flavefaciens and R. albus populations on rice straw was measured using real-time PCR with specific primer...

Bamboo is a potential major bio-energy resource. Tests were carried out to compare and evaluate the property of bamboo and rice straw pellets, rice straw being the other main source of biomass solid fuel in China. All physical properties of untreated bamboo pellets (UBP), untreated rice straw pellets (URP), carbonized bamboo pellets (CBP), and carbonized rice straw pellets (CRP) met the require...

This work describes an environmentally friendly method for pretreating rice straw by using 1-Allyl-3-methylimidazolium chloride ([AMIM]Cl) as an ionic liquid (IL) assisted by surfactants. The impacts of surfactant type (including nonionic-, anionic-, cationicand bio-surfactant) on the ionic liquid pretreatment were investigated. The bio-surfactant+IL -pretreated rice straw showed significant li...

the experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...

Inoculant of Trichoderma fungi was used to treat into rice straw at different times for decomposition to study “Effect of decomposed rice straw at different times on rice yields”. The decomposed rice straw at 1, 2, 3, 4 weeks gave C/N ratio from 24.12 31.71 in dry season and from 16.64 31.12 in wet season, these C/ N ratio was lower as compared to rice straw, which was not treated by inoculant ...

Composite panels using virgin and recycled high-density polyethylene (VHDPE and RHDPE) and five types of natural fibers including four rice straw components (i.e., rice husk, rice straw leaf, rice straw stem, and whole rice straw) and wood fiber as control were made by melt compounding and compression molding. Fiber characteristics and the influences of fiber type and loading rate on HDPE cryst...

The in situ application of rice straw enhances CH4 emissions by a large margin. The ex situ application of rice straw in uplands, however, may mitigate total global warming potential (GWP) of CH4 and N2O emissions from paddy-upland coexisting systems. To evaluate the efficiency of this practice, two field trials were conducted in rice-rice-fallow and maize-rape cropping systems, respectively. Y...
