PACKED BED REACTOR SYSTEM STUDY ON THE BIOSORPTION OF Cr(VI) FROM AQUEOUS SOLUTION USING CORN COB POWDER

ABSTRACT The current method used in the treatment of Cr(VI) uses biosorbents that are expensive hence the need for cheaper available biosorbent. In this study,potential use of corn cob powder biomass, as a bioremediation agent for the removal of Cr(VI)… Read More

LARVICIDAL POTENTIAL OF EXTRACTS OF Persea Americana SEED AND Chromolaena odorata LEAF AGAINST Aedes vittatus MOSQUITO

ABSTRACT The larvicidal activity of various solvent (ethanol, ethyl acetate and n-hexane) extracts of Persea americana seed and Chromolaena odorata leaves against Aedes vittatus mosquitowas analysed. The most potent solvent (n-hexane) extracts of both plants were fractionated using column chromatography and most effective fractions isolated… Read More

ISOLATION, PURIFICATION AND CHARACTERIZATION OF FREE AND IMMOBILIZED ALPHA-AMYLASE FROM BACILLUS LICHENIFORMIS

ABSTRACT The bacteria Bacillus licheniformis was cultured in nutrient agar and then incubated for 15h at 35oC. The bacteria cells were harvested by centrifugation after incubation. The cell free supernatant was used to estimate alpha-amylase activity. The alpha-amylase obtained was isolated and purified using ammonium sulfate… Read More

CHARACTERIZATION, INSECTICIDAL AND MOSQUITO REPELLENCY PROPERTIES OF ESSENTIAL OILS FROM HYPTIS SUAVEOLENS LEAVES

ABSTRACT Essential oils were extracted from the leaves of Hyptis suaveolens by hydro-distillation, Mosquitocidal effect was done through an experiment devised for the purpose of this research. The effect of the essential oils against mosquito larvae (larvicidal), mosquito repellency effect and physicochemical… Read More

ASSESSMENT OF THE RELATIONSHIP BETWEEN SOME TRACE ELEMENTS AND ANTIOXIDANT ENZYMES IN UNDER-FIVE CHILDREN WITH PROTEIN- ENERGY MALNUTRITION

ABSTRACT Assessment of the relationship between some trace elements and antioxidant enzymes was carried out on 98 under-five children with protein-energy malnutrition (PEM) and 98 age- and sex-matched apparently healthy children (control). The malnourished children involve those with Marasmus, Kwashiorkor… Read More

STUDY ON THE DESTABILIZATION OF LYSOZYME AND THE CHAPERONE-LIKE ACTIVITY OF ALPHA CRYSTALLIN

ABSTRACT Destabilization of Lysozyme and chaperone like action of alpha crystallin isolated from goat’s eye lens was investigated at various temperature ranges in phosphate buffer (pH 7.1) solution and dithiothretol (DTT). This was monitored spectrophotometrically at 260nm. The heat and… Read More
