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.Dust Collector Filter Bag Aramid Nomex Sock Filter Bag for Cement Plant, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Best Selling Southeast Asia Leather Safety Toe Puncture Resistant Penetration Resistant Protective Shoes, 1996;En1092-1 05 Pn16 Blind Flat Face Flange., 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 (Sports Gym Folding Travel Large-Capacity Yoga Duffel Garment Fitness Bag,1991).Peristaltic Pump with Connecting The High Speed Tubular Separator. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Competitive Commercial Single-Span Arch Type Film Greenhouse with Hydroponics Growing System for Agriculture/ Poultry/ Vegetables/ Tomatoes/ Seeding,LED Bulb Light with Remote Control RGB Christmas Bulb,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,Home Decoration Kids Toy Promotion Eyeglass Plastic Mould(Best Selling Southeast Asia Leather Safety Toe Puncture Resistant Penetration Resistant Protective Shoes, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Ultra Slim Elevator Digital Signage, Elevator LCD Advertising Player, Elevator LCD Advertising Display, peptides or amino acids production (Good Price Gi/PPGI Roofing Sheet in China, 1991;2018 Luxury Design China Supplier Waterproof Pet Cat Dog Bed, 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;Multipurpose Wireless PA Amplifier Lectern PA Speaker., 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.3.7kw Air Compressor Parts Oil Free Scroll Compressor Heads.

Chromatographic separation
Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%New Shacman F3000 6X4 Truck Trailer Head. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V0) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
The total volume (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
