The effects of extraction solvents (hexane, ethyl-acetate, acetone, ethanol, methanol, and water) on the content of phytochemicals including total polyphenols, flavonoids and condensed tannins, as well as antioxidant activities of walnut green husk were investigated. The results showed that extraction solvents significantly affected phytochemicals content and antioxidant activities of walnut gr...

BACKGROUND Rice cultivation produces two waste streams, straw and husk, which could be exploited more effectively. Chemical pretreatment studies using rice residues have largely focussed on straw exploitation alone, and often at low substrate concentrations. Moreover, it is currently not known how rice husk, the more recalcitrant residue, responds to steam explosion without the addition of chem...

Alcohol dehydrogenase (ADH) plays an important role in aroma volatile compounds synthesis of plants. In this paper, we tried to explore the relationship between CmADHs and the volatile organic compounds (VOCs) in oriental melon. Three different aroma types of melon were used as materials. The principle component analysis of three types of melon fruit was conducted. We also measured the CmADHs e...

The characteristics of an endoglucanase produced by a Trichoderma virens strain T9 newly isolated from a palm-fruit husk dump site, its physiological characteristics and enzyme production were studied. Whole cells of the depolymerizing-enzyme producing T. virens were applied to palm-fruit husk and bird performance characteristics when employed as poultry diet additive were considered. Endogluca...

The removal of heavy metals, especially from wastewater, has attracted significant interest because of their toxicity, tendency to bioaccumulate, and the threat they pose to human life and the environment. Many low-cost sorbents have been investigated for their biosorption capacity toward heavy metals. However, there are no reports available on the removal of Pb(II) from aqueous solution by of ...

A study was undertaken to determine effect of nutritional value of Melon husk (MH) and Palm oil slurry (POS) on quality of chevon obtained from West African Dwarf (WAD) goats fed finishing diets as follows: diet 1(0% MH, 0% POS); diet 2 (50% MH, 0% POS); diet 3 (0% MH, 50% POS) and diet 4 (50% MH, 50% POS), along with Panicum maximum as basal diet for all dietary treatment groups. After 60 days...

Lightweight ceramic materials in the form of bricks and blocks are widely used in modern construction. They may be obtained by adding of rice husk, rye straw, etc, as porous forming materials. Rice husk is a major by-product of the rice milling industry. Its utilization as a valuable product has always been a problem. Various technologies for utilization of rice husk through biological and ther...

The technological trend towards waste utilization and cost reduction in industrial processing has attracted use of Rice Husk as a value added material. Both rice husk (RH) and Rice Husk Ash (RHA) has been found suitable for wide range of domestic as well as industrial applications. Considering the importance and increasing demand of this material, a systematic study based on properties and indu...

The Rice Husk Ash is a cheap and readily available biosorbent for the removal of nickel ions from aqueous solutions. This investigation comprises of the equilibrium and kinetics study for biosorption of nickel ions from aqueous solutions using Rice Husk Ash powder as a biosorbent in a batch process. The Rice Husk Ash is obtained from a hotel near Andhra University campus, is dried in sunlight f...

The ability of coconut husk to remove methylene blue from solution was investigated. Factors such as initial dye concentration, contact time, adsorbent dosage and pH of solution were studied. Results show that Langmuir isotherm can be successfully applied to the methylede blue coconut husk system and that coconut husk is a suitable adsorbent for such a dye. Maximum adsorption capacity is 99 mg ...
