Hydrogen, peroxide was used as the substrate and phosphate buffer at a pH that have been determined to be the optimal pH for peroxidase activity for the specific sample type. The four plant root extracts showed an assay pH optimum of 7.5 for the Tamarindus indica (tamarind) and Eichhornia crassipes (water hyacinth), pH 5.5 for Dracaena snrculosa (spotted dracaena) and pH7.0 for Canlerpa leniillifera (grapes seaweeds) using Maehly and Chance method. Determination of peroxidase at 510 nm of the four extracts indicated that, spotted dracaena gave the highest peroxidase activity with 361.07U ml"1, followed by tamarind with 57.11U ml'1, then water hyacinth with 29.39 U ml'1 and lastly, grapes seaweeds with 7.55 U ml"1. The specific peroxidase activities of the spotted dracaena, water hyacinth, tamarind and grapes seaweeds are 0.3224, 0.2048, 0.0721 and 0.0341 U mg'1 respectively. The peroxidase of the four plant tissues that were kept at ultra low personal freezer for almost a week was degraded. CHAPTER I INTRODUCTION Peroxidase has been widely spread in various plants, animal tissues, bacteria and fungi [I]. There are peroxidases that have been obtained in the cystalline form such as the verdoperoxidase (myeloperoxidase) from leukocytes, lactoperoxidase from milk, cytochrome C peroxidase from yeast and horeseradish perosidase from horseradish [2]. Peroxidase from horseradish or HRP has been used in clinical analysis which is combined with other enzymes especially oxidase to determine many clinical important chemicals by spectrometry. Enzymes from peroxidase is conjugated to antibodies for ELISA [3,4].Soybean peroxidase has been proved to be a good catalyst, for phenol resins [4,5'j It has also widely used in the contamination of water polluted with phenols [6,7]. Mos* of this phenols and anilines are toxic chemicals [8]. Removal of these chemicals (Iron1, wastewater by peroxidase instead of the chemical and physical methods has some advantages such as low cost, no formation of by-product and efficiency. It has beea found that these phenols can be removed by enzyme-catalyzed polymerization using horseradish peroxidase that has little substrate specificity. Phenols from waste water are oxidized to phenoxy radicals, which undergo further reaction yielding various polymers and oligomers that are less toxic [9]. The polymers and oligomers products from the read ion can be removed from waste water since they have low solubility properties in water [6,10]. Peroxidase replaces the potential carcinogen formaldehyde in glues arid varnishes [7]. The baking industry in Europe has started using soybean peroxidase instead of potassium bromate in bread making and dough conditioning [7], Other functions of peroxidase are used to improved digestibility of wood and straw, used to bleach pulp, fiber in paper or textile industries [4, 6]. 1.1 OBJECTIVES The general objective of this study is to be able to determine peroxidase activity from the floats of Caulerpa lentillifera, roots of Tamarindus indica, Eichhornia crassipes, and Dracaena surculosa, by using UV-Vis spectrophometer. Specific objectives of this study are the following: 1 to be able to determine the optimum pH of the floats of Caulerpa lentillifera, roots of Tamarindus indica,FJchhornia crassipes, and Dracaena surculosa; 2 to determine the total protein concentration using Bicinchoninic Acid Protein Assay of the floats of Caulerpa lentillifera, roots of Tamarindus Indica, Eichhornia crassipes, and Dracaena surculosa; 3.
