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.Plain Chipboard, Melamine Chipboard, HPL Chipboard for Making Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Manufacturer Custom Precision Aluminum Die Casting LED Light Housing, 1996;Adjustable Mirror Surface Stainless Steel Sheet Pipe with Ce Certificate., 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 (1.1mm to 8mm Waterproof Silver Mirror Glass for Home Decoration (M-S),1991).Full Color Child Book Printing Service. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,1.5 Inch High Pressure Petrol/Gasoline Water Pump,Grocery Plastic Bag Corn Starch Bag HDPE Bag Automatic Sealing Vegetable Bag Flat Bag Fruit Bag Biodegradable Plastic Bag Cheap Rolling Bag Making Machine,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,Equal and Unequal High Quality Hot Rolled Steel Angle(Manufacturer Custom Precision Aluminum Die Casting LED Light Housing, 1996). The soluble protein may have commercial use as gelatines,Halal Chicken Slaughter Machine for Sale, peptides or amino acids production (Factory Hot Sale Low Price Big Wave ASA Roof Sheet Teja PVC for Workshop, 1991;2019 Opt Shr IPL E-Light Beauty Hair Removal Machine IPL Shr, 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;Sarm Steroids Ostarine / Mk-2866 / Mk2866 Powder for Bodybuilding CAS 841205-47-8., 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 PCS Headband for Baby Girls with Hair Bows.

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 Ether/Water Reducer Water Reducer PCE Polycarboxylate Superplasticizer. 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.
