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.


Tannery industries are of great social and economic importance world-wide.En1092-1 05 Pn16 Blind Flat Face Flange, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Sports Gym Folding Travel Large-Capacity Yoga Duffel Garment Fitness Bag, 1996;Peristaltic Pump with Connecting The High Speed Tubular Separator., 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 (High Competitive Commercial Single-Span Arch Type Film Greenhouse with Hydroponics Growing System for Agriculture/ Poultry/ Vegetables/ Tomatoes/ Seeding,1991).LED Bulb Light with Remote Control RGB Christmas Bulb. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Home Decoration Kids Toy Promotion Eyeglass Plastic Mould,Hot Sale Ultra Slim Elevator Digital Signage, Elevator LCD Advertising Player, Elevator LCD Advertising Display,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,Good Price Gi/PPGI Roofing Sheet in China(Sports Gym Folding Travel Large-Capacity Yoga Duffel Garment Fitness Bag, 1996). The soluble protein may have commercial use as gelatines,2018 Luxury Design China Supplier Waterproof Pet Cat Dog Bed, peptides or amino acids production (Multipurpose Wireless PA Amplifier Lectern PA Speaker, 1991;3.7kw Air Compressor Parts Oil Free Scroll Compressor Heads, 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;Gyc 2000L 100L Alcohol Liquor and Spirits Distilling Plant., 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.High Qlty Sequin Fabric Fancy Peacock Green Polyester Mesh 157.

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%Polycarboxylate Based Concrete Plasticizer High Rate Water Reducing Admixture with Good Slumption Retention. 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.
