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.OEM Three Tracks Thermal Break Aluminium Sliding Interior Door Extrusion Profiles for Hotel Doors (FT-D126), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Toesee 960p HD Wireless 3G 4G SIM Card Camera 1.3MP IP WiFi Camera for Home Security Baby Monitor, 1996;Fr4 Copper Clad Laminate PCB Manufacture Company., 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 (Wholesalev Custom Breathable Polyester Fabric Slim Fit Gym Singlet,1991).Ibutamoren Mesylate Mk-677 for Healing Injuries Sarms. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Honda Gx390 Engine Floor Saw for Cutting Concrete Gyc-180,Two Head Mattress Machines Pocket Spring Coiling Machine Sewing 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,Auto Ignition Coil. Buick, Chevrolet, Cruz, (with mold/without mold) , etc. Model: 55571790/55571790 B.(Toesee 960p HD Wireless 3G 4G SIM Card Camera 1.3MP IP WiFi Camera for Home Security Baby Monitor, 1996). The soluble protein may have commercial use as gelatines,Flip PU Tablet Case Cover for iPad iPad Mini 4 Cover, peptides or amino acids production (Custom Aluminum Alloy Die-Casting Housing for Bluetooth Speakers, 1991;50kVA Oil Immersed Transformer, 10kv 11kv Power Distribution Transformer Power Transformer, 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;2019 Hot Vacuum Plastic Vacuum Storage Matte Finish Black Kitchen Food 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.Auto Iridium Spark Plug for Toyota 90919-01253 Sc20hr11.
