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.Nylon Weatherproof PA6 Strain Relief Cable Gland, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Steel Roller Embossed Paper 2019 New Design, 1996;Hot Saled Building Material 304 Cold Rolled Stainless Steel Coil., 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 (Factory Price DIN5685 Galvanized Marine Anchor Link Chain,1991).Hot Salecustom Silicone Finger Rings Promotional Gift (SLF-SR001). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,6X6 20m3/20000litres Liquid Tank off Road Fuel Transportation Tanker Truck,High Level Application Waterproof Plastic Box,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,Automatic Pet Plastic Glass Bottle Pure Water Treatment Filter Purifier Juice Beverage Liquid Filling Sealing Bottling Labeling Packing Packaging Machine(Steel Roller Embossed Paper 2019 New Design, 1996). The soluble protein may have commercial use as gelatines,Steel Frame H Beam Prefab Building Farm House Shed Shelter Poultry House Steel Structure Warehouse, peptides or amino acids production (Water Slide for Indoor Play Structure, 1991;Military Camelback Hydration Pack Wholesale Camo Hydration Pack 3L Bladder, 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;1220*2440mm Concrete Formwork black film faced plywood., 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.Washami Teeth Care for Whitening Cool Mint Toothpaste.
