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.Single Phase Digital Electric Power Meter, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fashion Jewelry 925 Sterling Silver Diamond Jewellery Ring with Butterfly, 1996;2W 100lm LED Solar Lawn Light for Garden or Yard Lighting., 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 (Single Phase 220V AC 3 1.8kw Qdx Submersible Clean Water Pump,1991).28mm China High Quality Supplier Screw Cannon Cap for Bottle. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Good Quality R134A Refrigerant Copper Tube Fin Heat Exchanger,Non-Standard Customized Junction Waterproof Box Electronic ABS Plastic Enclosure,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,Nonwovenface Mask Production Line(Fashion Jewelry 925 Sterling Silver Diamond Jewellery Ring with Butterfly, 1996). The soluble protein may have commercial use as gelatines,Wholesale Professional Indoor&Outdoor Trampoline Park, peptides or amino acids production (Cheap Original Laptop for DELL Inspiron 13 7000 13.3 FHD Laptop, I7-8550u 8GB 256GB SSD, Win 10, 1991;HVAC Ventilation Supply Air Return Grille Air Vent, 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;High Quality Luxury Design French Style MDF/HDF Molded Wood Door Skin Solid Wooden 2 Panel Wood Door., 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.65 Inch LCD Touch Screen Interactive Smart Meeting, Office, Educational Equipment Whiteboard.
