THERMODYNAMICS AND KINETICS OF THERMO-INACTIVATION AND REGENERATION OF PARTIALLY PURIFIED PEROXIDASE FROM Gongronema latifolium LEAVES

ABSTRACT Peroxidase activity from G. latifolium was done to see whether it could be used in industries. Crude peroxidase was extracted from G. latifolium with 0.05M sodium phosphate buffer of pH 6.0; 70% ammonium sulphate saturation to precipitated protein with the highest G. latifolium peroxidase activity. After gel filtration, two major peaks were seen and […]

THE EFFECT OF HYDROGEN PEROXIDE ON PEROXIDASE (EC 1.11.1.7) FROM GONGRONEMA LATIFOLIUM

ABSTRACT Peroxidase (EC 1.11.1.7) extracted from Gongronema latifolium was purified, on a two-step purification process of ammonium sulphate precipitation followed by dialysis. The enzyme was purified 6.8 fold with a specific activity of 2.04 when o-dianisidine was used as substrate. When the enzyme was subjected to different concentrations of hydrogen peroxide and o-dianisidine, the peak […]

THE EFFECT OF ETHANOL EXTRACT OF Theobroma cacao POLYPHENOL ON ISOPROTERENOL-INDUCED MYOCARDIAL INFARCTION IN WISTAR RATS

ABSTRACT This study investigated the effect of cocoa polyphenol on isoproterenol-induced myocardial infarction in Wistar rats. Polyphenol was extracted from cocoa using a hydroalcohol solvent. Forty albino rats divided into six groups of four rats each were used for the study. Groups 3, 4, 5 and 6 were pretreated with the extract (300, 500 and […]

RENAL BIOCHEMICAL CHANGES OF PREGNANCY-INDUCED HYPERTENSION IN PREGNANT WOMEN ATTENDING TERTIARY HOSPITALS IN ENUGU STATE

ABSTRACT Pregnancy induced hypertensive disorders have become very common medical complication in Nigeria with its attendant morbidity and mortality. The morbidity and mortality may be associated with its possible effect on the kidneys which was studied. Results of the electrolyte changes from this study showed that there was non-significant difference (p>0.05) in sodium ion concentration […]

PRODUCTION, PARTIAL PURIFICATION AND CHARACTERIZATION OF CELLULASE BY ASPERGILLUS NIGER FROM SUBMERGED FERMENTATION OF GRAPE BAGASSE

ABSTRACT The increase in agricultural practices has necessitated the judicious use of agricultural wastes into value added products. In this study the ability of selected cellulosic substrate to induce cellulase production by Aspergillus niger and the ability of the induced enzyme to hydrolyze the cellulosic substrate were assessed. The enzyme was produced by submerged fermentation […]

PRODUCTION OF Aspergillus niger GLUCOAMYLASE USING GUINEA CORN STARCH AMYLOPECTIN AS THE ONLY CARBON SOURCE

ABSTRACT This study was aimed at the production of glucoamylase which can be utilised for starch hydrolysis. A fourteen days experimental study was carried out to determine the day of highest glucoamylase activity. Day five and day twelve of the fourteen days experimental study had the highest glucoamylase activity. The specific activity for the crude […]
