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.6X420mm Headband Binocular Loupes Dental Magnification Surgical Lightweight Hesperus, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Temperature Side Opening AAC Autoclave, AAC Block Making Machine, 1996;PVC Transparent/Clear/Opaque Film for Covering, Packaging, PVC Liner, Protection, Wrap., 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 (Multifunctional 3 in 1 E-Light Dpl IPL +Picosure + RF for Tattoo Removal & Hair Removal & Skin Rejuvenation,1991).Teflon Seal/Seals Spring Energized, PTFE Spring Energized Seal. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,1929 Weifang Huamei Home Use Handy Skin Care IPL Shr Laser Hair Removal Machine,New Mason Cup Frosted Drink Bottle Juice Glass Mason Jar,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,Green Color PVC Anti Dazzle Panel(High Temperature Side Opening AAC Autoclave, AAC Block Making Machine, 1996). The soluble protein may have commercial use as gelatines,ISO Approved Self-Cleaning Permanent Belt Magnetic Iron Ore Separator, peptides or amino acids production (XL-21 Motive Electrical Switchgear Power Cabinet, 1991;Digital Converter 110VAC 60Hz to 220VAC 50Hz Sine Wave Frequency Inverter, 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;Furniture Grade E1 Glue Plywood with Competitive Price., 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 Pressure Hose & Hydraulic Hose SAE 100r1at/ DIN En853 1sn.

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%Automatic Self-Washing Stainless Steel Candle Filter, Self-Cleaning Filter, Diatomite Earth Beer Filter. 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.
