presence of heavy metals in the aquatic systems has become a serious problem. as a result, therehas been a great deal of attention given to new technologies for removal of heavy metal ions from contaminated waters. adsorption is one of the effective methods for removal of toxic heavy metal such as chromium (vi). in the present study, adsorbent is prepared from rice husk, a low cost by product f...

Agroindustrial wastes such as spent grain, cocoa husk, rice bran and sawdust, unamended and amended with cattle, poultry and goat droppings were studied as to their effect on growth, fruit yield and nutrient composition of tomato (Lycopersicum escutentum Mill) in two experiments. Analysis of the wastes showed varying nutrient composition with C:N values of 11.1, 12.5, 23.3 and 18.2 respectively...

The objective is to evaluate the primary mechanical and physical properties of particleboard made from hammer-milled rice straw particles of six different categories and two types of resins. The results show the performance of straw particleboards is highly dependent upon the straw particle size controlled by the opening size of the perforated plate inside the hammer-mill. The static bending an...

Cereal Chem. 87(5):403–408 This research studied developing quick cooking brown rice by investigating the effect of ultrasonic treatment at different temperatures on cooking time and quality. The medium grain brown rice was ultrasonically treated in water at temperatures of 25, 40, and 55°C for 30 min and then dried by air at 25°C to its initial moisture content (11.0 ± 0.6%, wb) before cooking...

As the cost of mineral fertilisers increases globally, organic soil amendments (OAs) from agricultural sources are increasingly being used as substitutes for nitrogen. However, the impact of OAs on the production of greenhouse gases (CO2 and N2O) is not well understood. A 60-day laboratory incubation experiment was conducted to investigate the impacts of applying OAs (equivalent to 296 kg N ha(...

This paper reported the purification and kinetic parameters characterization of an alkaline protease produced from Bacillus subtilis through submerged fermentation process using rice husk as growth supporting substrate (by-product of rice industry) collected from Pearl Rice Mill Hafiz Abad, Faisalabad. Bacillus subtilis was cultured in fermentation medium under some pre-optimized growth conditi...

Cereal Chem. 79(3):465–469 The structural features of rice starch that may contribute to differences in the functionality of three long-grain rice cultivars were studied. Dried rough rice samples of cultivars Cypress, Drew, and Wells were analyzed for milling quality, grain physical attributes, and starch structures and physicochemical properties. Drew was lower in head rice yield and transluce...
