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.Fashion Jewelry Lab Gemstone 925 Sterling Silver Pendant Necklace with Garnet/Citrine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Sm5r30602b Auto Car Ls1 Komatsu Kobelco Engine Suzuki GM Automobile Wiring Harness, 1996;Biomass Drum Wood Chipper with Competitive Price., 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 (High - Tech RFID in Airports Automated Check in and UHF RFID Bag Tags,1991).Forged Steel Pressure Sealed Bonnet Globe Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plastic Injection Moulding Machine Supplier / Factory /Manufacturer,Microfiber Magnetic Custom Bath Set 100% Printed Kitchen Tea Towels,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,15kv-35kv Medium Voltage XLPE Insulated Underground Urd Power Cable(Sm5r30602b Auto Car Ls1 Komatsu Kobelco Engine Suzuki GM Automobile Wiring Harness, 1996). The soluble protein may have commercial use as gelatines,Aluminum Die Casting Waterproof Junction Box IP67 Aluminum Outdoor Enclosure, peptides or amino acids production (80W All in One Outdoor LED Street Light Solar Lamp, 1991;Hot Sale Safety Vinyl PVC Flooring, 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;Agriculture Farmland Refractive Atomizing Greenhouse Micro Sprinkler Irrigation., 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.Horizental Stainless Steel Food Grade Milk Tank for Milking.
