Integration of renewable deep eutectic solvents with engineered biomass to achieve a closed-loop biorefinery for 12 h followed by water extraction for an additional 8 h. The extractives-free samples were ball-milled using a Retsch Ball Mill PM 100 in a ZrO 2 jar 50-mL Natural deep eutectic solvent mediated pretreatment of rice straw

We measured fine root lignin content in 73 plots of a field biodiversity experiment containing a pool of 60 grassland species using the Acetylbromid AcBr method. is well predictable with

2020-5-8As many as 400000 people in Britain have caught the coronavirus and 20000 citiens are being infected each day experts claimed today

In a large ball mill the shell might be 3 m in diameter and 4.25 m long. The balls are 25 to 125 mm in diameter the pebbles in a pebble mill are 50 to 175 mm in sie. A tube mill is a continuous mill with a long cylindrical shell in which material is ground for 2 to 5 times as long as in the shorter ball mill

Ionic liquid IL-assisted pretreatment of lignocellulosic biomass has been extensively studied. Cellulose and hemicelluloses are rich resources of sugars for biofuels. Lignin is a valuable feedstock for aromatic-based platform chemicals. In this study a series of ionic liquids ILs were prepared with one-step sy

Switchgrass Panicum virgatum L. is a promising bioenergy feedstock because it can be grown on marginal land and produces abundant biomass. Recalcitrance of the lignocellulosic components of the switchgrass cell wall to enymatic degradation into simple sugars impedes efficient biofuel production. We previously demonstrated that overexpression of OsAT10 a BAHD acyltransferase gene enhances

2020-5-9Rice is the seed of the grass species Orya glaberrima African rice or Orya sativa Asian rice. As a cereal grain it is the most widely consumed staple food for a large part of the worlds human population especially in Asia and Africa.It is the agricultural commodity with the third-highest worldwide production rice 741.5 million tonnes in 2014 after sugarcane 1.9 billion tonnes

The experimental design used was a randomied block design with two treatment factors and three replications. The first treatment factor is the variety consisting of Antin - 1 Antin - 2 and Antin - 3. The second treatment factor is the bokashi dose of rice straw consisting of four treatments 0 tonsha 5 tonha 10 tonsha and 15 tonsha

Tian Liu a Yong Lei b Qingwen Wang a Sunyoung Lee c and Qinglin Wu b High-density polyethylene HDPE and natural fiber composites were prepared by melt compounding and injection molding

To investigate changes on the physicochemical characteristics of wheat straw by mechanical ultrafine grinding wheat straw powders of four different particle sies and distributions were produced using a sieve-based Retsch ZM100 grind mill and CJM-SY-B ultrafine vibration grind mill. Changes on the microstructure and physicochemical characteristics of the different powders were assessed by

2020-4-27The method to find kappa of pulp is described in TAPPI T236. Lignin in Pulp Commercial pulp range in lignin content from 1.0 for soft cook chemical pulp about 8 for hard cook chemical pulp and up to 16 for semi-chemical pulp.In general lignin affects the properties of pulp

It was found that the degree of crystallinity of cellulose in the composition of wheat straw decreases from 70 to 19 in the process of mechanical activation in an AGO-2 planetary ball mill the destruction of cellulose chains is observed predominantly along the 010 direction. The grinding limit was reached after 10 minutes of activation

Production of advanced biofuels from woody and herbaceous feedstocks is moving into commercialiation. Biomass needs to be pretreated to overcome the physicochemical properties of biomass that hinder enyme accessibility impeding the conversion of the plant cell walls to fermentable sugars. Pretreatment also remains one of the most costly unit operations in the process and among

Bioprocessing of wheat straw into nutritionally rich and digested cattle feed the bulk samples were ground in a laboratory Willey mill using 1 mm sieve and stored in polythene bags for further

Index terms Agricultural waste rice husk ash broiler bed ash This work can open a new field of applications for the ashes coming from agroindustry wastes and related to the production of lightweight cement based materials. It was then ground in a ball mill for about 10h00

Rice Yield and Nitrogen Utiliation Efficiency under Alternative Straw Management Practices. with a rolling ball mill and analyed for total N by combustion. Rice straw contains about 80

Rice straw has considerable potential as a raw material for bioethanol production. Popping pretreatment of rice straw prior to downstream enymatic hydrolysis and fermentation was found to increase cellulose to glucose conversion efficiency. The aim of this study was to investigate the influence of popping pretreatment and determine the optimal enyme loading using a surface response design

In this work carbonaceous materials bearing only weakly acidic COOH and phenolic OH groups were directly prepared by the pyrolysis of lignin and KOH in black liquor generating from rice straw that was pretreated with KOH aqueous solution. The synthesied carbon materials were used for the hydrolysis of cellulose or the alkali pretreated rice straw in water after mixed ball-milling
