The Anaerobic Digestion of Rice Straw: A Review

Critical Reviews in Environmental Science and Technology, 2013
The anaerobic digestion of rice straw has been studied for the past century, but the renewable energy potential is barely utilized. Greenhouse gas emissions from rice fields can be substantially reduced if straw is removed. Methane yields ranging from 92 to 280 l/kg of volatile solids have been achieved. Optimal digestion conditions such as pH (6.5–8.0)

Determination of quintrione in rice, rice husk and rice straw and exploration of its dissipation from rice straw

Journal of Environmental Science and Health, Part B, 2021
A rapid and sensitive method for the identification and quantification of quintrione residue in brown rice, rice husk, and rice straw matrices was developed and validated. Samples were extracted with acetonitrile, purified with octadecylsilane (C18) and graphitized carbon black (GCB) sorbents, and quantified using ultrahigh-performance liquid ...

Actinomycetes in rice straw decomposition

Waste Management, 2007
Actinomycetes are well known as lignocellulose decomposers. Forty-two cellulolytic actinomycete isolates have been recovered from soil. Those were identified to the genus level as: Streptomyces (26 isolates), Nocardiopsis (5 isolates), Micromonospora (4 isolates), Nocardioides (4 isolates) in addition to three isolates tentatively identified as ...

Biomethanation of rice and wheat straw

World Journal of Microbiology & Biotechnology, 1994
When rice or wheat straw was added to cattle dung slurry and digested anaerobically, daily gas production increased from 176 to 331 l/kg total solids with 100% rice straw and to 194 l/kg total solids with 40% wheat straw. Not only was methane production enhanced by adding chopped crop residues but a greater biodegradability of organic matter in the ...

Effect of unmodified rice straw on the properties of rice straw/polycaprolactone composites

Research on Chemical Intermediates, 2014
The composite materials based on rice straw (RS) fiber and polycaprolactone (PCL) were prepared by a solution-casting method and characterized. The composites were prepared using different fiber loadings (1.0, 3.0, 5.0, and 7.0 wt%). The prepared composites (Cs) were characterized by using powder X-ray diffraction (XRD), scanning electron microscopy ...

PROCESSING RICE STRAW INTO CELLULOSE

Bulletin of the Korkyt Ata Kyzylorda University, 2022
В работе рассматривается переработка многотоннажного сельскохозяйственного отхода – рисовой соломы в целлюлозу, которая может найти применение для производства бумажных изделий. Процесс десиликации рисовой соломы проводили в условиях сверхвысокочастотного облучения при мощностях 100 и 180 Вт в течение 5-40 мин ...

Acetylation of rice straw for thermoplastic applications

Carbohydrate Polymers, 2013
An inexpensive and biodegradable thermoplastic was developed through acetylation of rice straw (RS) with acetic anhydride. Acetylation conditions were optimized. The structure and properties of acetylated RS were characterized by fourier transform infrared (FTIR), solid-state (13)C NMR spectroscopy, X-ray diffractometer (XRD), scanning electron ...

Microwave torrefaction of rice straw and pennisetum

Bioresource Technology, 2012
Microwave torrefaction of rice straw and pennisetum was researched in this article. Higher microwave power levels contributed to higher heating rate and reaction temperature, and thus produced the torrefied biomass with higher heating value and lower H/C and O/C ratios.

Rice straw decomposition in rice-field soil

Plant and Soil, 1988
Rice straw, buried in a rice-field during the dry season decomposed at a rate of 0.0075 day-1. Seventy five percent of the biomass, 70 percent carbon, 50 percent nitrogen and 30 percent phosphorus remained after 139 days of decomposition. Rice straw decomposition furnished 33% N and 8% P of the total nitrogen and phosphorus provided by man.

Availability of rice straw Si to rice plants

Soil Science and Plant Nutrition, 1991
Abstract A pot experiment was conducted to estimate the availability to rice plants of Si contained in rice straw. To separate the effect of straw application on Si availability in soil, two kinds of rice straws, which contained 15.5% (+ Si straw) and 0.2% SiO2 (—Si straw), were used at a rate of 1% of air-dry soil, respectively.
