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.Orange Silica Gel 2-4 mm with High Quality, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (2019 Top Quality USB-C Docking Station with SD Card Reader Dp VAG HDMI, 1996;aluminium discs for fry pan alloy 1060 1100 1050 3003., 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 Quality Insulated Double Wall Bamboo Glass Water Bottle,1991).Aroma Reed Diffuser with Ratten Sticks for Home Fragrance. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Fashion Ladies Backpack PU Leather Backpack,Suction Filter Cylinder Match 48 Series Filter Brands,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,I10 Tws Mini Bluetooth 5.0 Earphone Twins Wireless Headphones Air Pods in Ear Earbuds Sport Headset Stereo for Apple iPhone Samsung Xiaomi(2019 Top Quality USB-C Docking Station with SD Card Reader Dp VAG HDMI, 1996). The soluble protein may have commercial use as gelatines,16oz Square Shape Colors Glass Mason Jar with Embossed Design, peptides or amino acids production (Poultry Livestock Transport Double Floor Vehicle/Double Box Van Double Floor Animal Cattle Transport Semi Trailer, 1991;Aerobics and Exercise Highly Durable Floors of Offices and Commercial Rooms, 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;100ml Plastic E Liquid Vape Cig Juice Dropper Bottle., 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.Eco-Friendly Round Head Screw Stud Flange Hexagon Bolt for Building.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,HDPE Skew 45 Degree Drainage Pipe Fitting Sewage Tee.

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%Flat Face Stainless Steel Female Jic Quick Release Coupling. 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.
