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.Business Class Eyeshade Quality Travel Eye Mask Sleeping Eye Cover, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Price 6mm Stainless Steel Wire Rope 7*7, 1996;Temperature Sensor Customized Thermostat for Industrial Appliances., 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 (Outoodr Svgc Composite Compensation with Capacitors for Reactive Power,1991).2019 Wholesale New Notebook Computers for DELL Inspiron 17.3 Core I7-8550 16GB RAM 2tb HDD Radeon 530 DVD Win10 Laptop. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Top China Forklift Supplier & Manufacturer,Blue White Yellow Red Black Nylon Mosquito  Window Netting,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,Hot Sale Spraying Drying Equipment(Factory Price 6mm Stainless Steel Wire Rope 7*7, 1996). The soluble protein may have commercial use as gelatines,Food Kitchen Mini Milling Electric Grinding Maize and Flour Making Machine, peptides or amino acids production (LED Solar Powered Traffic Blinking Emergency Light, 1991;Die-Casting LED Projector Light 840W Outdoor Sport Field Light High Mast Light 150lm/W, 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;Fiberglass Pultruded Pipe, FRP Profiles, FRP Pultrusion Tube., 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.Humic Acid Bio-Fertilizer Granule Making Machine.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Pen Type pH Meter pH-031&0.00-14.00pH Tester.

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%8mm Heavy Duty Nails U Shaped Galvanized Staples. 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.
