Occurence and Characteristics of HydroCarbon-Utilizing Bacteria in Nigerian Soils Contaminated with Spent Motor Oil
(1987)
Soil samples were collected from four different oil-contaminated sites in Lagos, Nigeria, Enrichment of soil samples in a mineral salts medium containing SAE 40 motor oil as carbon source resulted in the isolation of eleven ...
Degradation of Commercial Detergent Products by Microbial Populations of the Lagos Lagoon
(1997-01-28)
The biodegradability potentials of three detergent products with the trade names Omo, Teepol and sodium dodecyl sulfate (SDS) by the native bacteria of the Lagos lagoon was carried out using the lagoon die-away method. ...
Occurrence and Distribution of Sulphate-Reducing Bacteria in a Polluted Lagoon
(The faculty press, Cambridge, 1991-01)
The presence and distribution of sulphate-reducing bacteria (SRB) in the sediment and water from four strategic points on the Lagos Lagoon were assessed using the most probable number technique. All the samples were ...
Short Communication: Purification and Properties of a Glucose-Forming Amylase of Lactobacillus Brevis
(Rapid Science Publishers, 1995)
An extracellular glucose-forming amylase was produced by Lactobacillus brevis isolated from ‘Kagasok tea’. The enzyme was purified 70-fold and had optimal activity at 55 oC and pH 6.5. Its Km value for starch was 0.27 mg ...
Utilization and Degradation of an Ester-Based Synthetic Lubricant by Acinetobacter lwoffi
(Kluwer Academic Publishers, 1996)
An oil-degrading bacterium, Acinetobacter lwoffi, isolated by elective culture from the Medway estuary, utilized an ester-based synthetic lubricating oil EMKARATE DE 155 as sole carbon and energy source. Analysis of culture ...
Effect of Viscosity on the biodegradability of Automotive Lubricating Oils
(Butterworth- Heinemann Limited, 1991-08)
Hydrocarbon-utilizing bacteria were isolated by enrichment from water samples collected from the Lagos lagoon and identified as species of Achromobacter, Acinetobacter, Alcaligenes, Arthrobacter, Bacillus, Flavobacterium, ...
Biodegradation of Petroleum Hydrocarbons Under Tropical Estuarine Conditions
(Rapid Communications of Oxford Limited., 1990-09)
The physic-chemical parameters of water samples collected from three points in the Lagos lagoon were studied for 12 months. Salinity varied seasonally but the temperature, pH, dissolved O2, conductivity, NO3 and HPO42- ...
Genotoxicity of Oilfield Wastewater in Nigeria
(1997-04-09)
The general toxicity (root growth inhibition and malformation) and genotoxicity (induction of chromosome aberrations in root cells) of an oil field wastewater have been investigated by the Allium test. A series of 10 small ...
Hydrocarbon Degradation Potentials of Yeast Isolates from a Polluted Lagoon
(1993)
The population counts of heterotrophic and hydrocarbon-utilising yeasts were monitored at six sampling stations in the Lagos lagoon over a four-week period. Although the population counts were relatively constant in each ...
Characterisation of a Neutral Protease Produced by Micrococcus Luteus
(1995-05-26)
A proteolytic enzyme produced by a cassava-fermenting strain of Micrococcus luteus was extracted and purified 50-fold by gel filtration and ion exchange chromatography. The optimum pH for the enzyme was 7.0, the optimum ...
