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.Type Price Prefabricated Roof Tile in Sudan, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stackable Mahogany Color Wooden Chiavari Chair with Soft Cushion, 1996;Factory Supply 100% Natural Epimedium Extract for Male Health., 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 (Stainless Steel Bathroom Accessories 304 Polished or Brushed Finish No Chrome No Rust,1991).Type 0242 IP67 220V-415V 6h 3p+E 3pin 32A Industrial Plug. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Top10 1080P H. 264 P2p CCTV WiFi IP Camera,Plain Chipboard, Melamine Chipboard, HPL Chipboard for Making Furniture,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,Manufacturer Custom Precision Aluminum Die Casting LED Light Housing(Stackable Mahogany Color Wooden Chiavari Chair with Soft Cushion, 1996). The soluble protein may have commercial use as gelatines,Adjustable Mirror Surface Stainless Steel Sheet Pipe with Ce Certificate, peptides or amino acids production (1.1mm to 8mm Waterproof Silver Mirror Glass for Home Decoration (M-S), 1991;Full Color Child Book Printing Service, 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;1.5 Inch High Pressure Petrol/Gasoline Water Pump., 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.Grocery Plastic Bag Corn Starch Bag HDPE Bag Automatic Sealing Vegetable Bag Flat Bag Fruit Bag Biodegradable Plastic Bag Cheap Rolling Bag Making Machine.
