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.Cog Graphic FPC LCD Display Module, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Power Fitting- Hot DIP Galvanizing Bolt with Nut, 1996;Slewing Gear for Tower Crane Slewing Winch Reducer., 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 (Full Automatic Tomato Ketchup Sauce Sachet Packaging Machine,1991).7-Gauge Polyester/Cotton Knitted Gloves with PVC DOT on One Side. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Shoes Sandals Sneakers Comfortable Foam Injection Moulded Shoes,Double Arm Motorized Multifunction Medical Equipment for Hospital Gas System,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,Strong and Comfortable Flexible Wave Back Chair for Banquet (HM-S8)(Power Fitting- Hot DIP Galvanizing Bolt with Nut, 1996). The soluble protein may have commercial use as gelatines,Telescopic Handle Easy Cleaning Double Sides Chenille & Microfiber Flat Mop, peptides or amino acids production (Patent LED Tri-Proof light Fixture 30W, 3FT 3000lm IP66 Approved, 1991;Single Screw Extruder for Plastic PP/PE Pipe Production Line, 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;Packing 50ml Refill Reed Diffuser Glass Bottle with Silver Screw Neck., 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.Dog Hook Spring Snap Hook Swivel Eye Bolt Snap Hook Key Hook Alloy Hook Swivel Hook Metal Hook for Handbag Luggage.
