RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Road Construction Fabric Non-Woven Geotextile 200GSM, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Polymer Modified Cement Based Elastic Waterproof Coating, 1996;Best Thermal Insulation Material Aerogel Powder for Greenhouse Steam Pipe., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Heat-Sealed Laminated Bag with Hexagonal Bottom Gusset,1991).Fashion Shoulder Backpack Handbag School Bag. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Coating Application CMC / Coating Material Grade CMC LV, Mv, Hv / Coating Material Grade CMC Medium Viscosity,Hot Sale Cute Food Plastic Pet Slow Feed Dog Bowl,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,FTTH Fiber Optic Fusion Splicing Toolkit(High Polymer Modified Cement Based Elastic Waterproof Coating, 1996). The soluble protein may have commercial use as gelatines,High Speed Cable Wire Winding Braiding Machine, peptides or amino acids production (22 High Rubber Mixing Mill, High Accuracy Lab Rubber Two Roll Mill, 1991;High Temperature Alternative Stainless Steel Band in Different Package, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Water Cooled Low Temperature Screw Chiller for Industrial Workshop., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Home Machine 2019 New Commercial Treadmill Gym Equipment.
