Effects of Nitrogen on Hull Characters and Its Causes in Yangdao6;

Grain Capability of Photosynthates and Its Relationship with Hull in Rice(Oryza Sativa L.);

Pot experiment was carried out to investigate effect of hull on growth of brown rice, using Japonica cultivar Nipponbare and Indica cultivar Yangdao 6 as materials.

Physical/chemical structure evolution of rice husk particles during gasification process;

Physical structure evolution of rice husk particles during high speed pyrolysis;

Fractal characteristics of rice husk/char particles prepared by pyrolysis process;

The removal of copper from aqueous solution by rice bran, a low-cost adsorbent, was studied.

Characterization of chaff and biosorption of copper and lead ions from aqueous solution;

The experiments of production of single cell protein were carried out from hydrolysate of rice hull by Candida arborea AS1 257 in the external loop airlift bioreactors with a height to diameter ratio of 2 9 and a ratio of rise diameter to downcomer diameter of 6 6 The effects of gas flow rate,liquid volume and gas sparger hole diameter on single cell protein production were investigated.

In this paper,the technology conditions of single cell protein culture was investigated under the shaking flask and in ten liter air lift fermentor with the Candida arborea in the culture medium containing rice hull hydrolysate as carbon source and product of hydrolysata with NH 3H 2O neutralization as nictrogeu source.

Using two-step hydrolysis by diluted sulphuric acid under common pressure,the yield of reduced sugar to rice husk is 26.

The mechanism of diffusion in the rice husk parti-cles is discussed.
