The physicochemical and flocculating properties of a bioflocculant produced by a bacterial consortium composed of Halomonas sp. Okoh and Micrococcus sp. Leo were investigated. The purified bioflocculant was cation and pH dependent, and optimally flocculated kaolin clay suspension at a dosage of 0.1 mg/mL. The flocculating activity of the bioflocculant was stimulated in the presence of Ca2+, Mn2...

The effect of dicyclohexylamine on seven freshly isolated bacterial strains of mastitis pathogens was studied. Streptococcus uberis was the most sensitive strain investigated, since 5 mM-dicyclohexylamine totally arrested its growth and 1.25 mM of the drug caused 60% growth inhibition. The Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa strains were also sensitive to the drug...

Tomato samples were dried at different frequency of light using clothes of different colours with wooden drying fabrication. The proximate composition and microbial count of the Tomato fruits were determined. Results showed that temperature and relative humidity of the environment affected the rate of drying of tomato as well as the growth of spoilage organisms in the fruits. Highest temperatur...

Dimethylamine was formed from trimethylamine in soils of different pH values. The rate of disappearance of the secondary amine from soil was affected by pH and was markedly reduced under anaerobiosis. The accumulation of dimethylamine in cultures of Micrococcus sp. provided with trimethylamine depended on the nitrogen sources available to the bacterium but was not greatly influenced by the C-N ...

Cabbage is a dietary source of micronutrients, vitamins and fiber, vital for human health. samples this study were obtained from selected markets in Ibadan, Nigeria. Serial dilutions membrane filter techniques used to determine microbial load profile the samples. Appropriate culture media detect presence Fungi Bacteria isolated included; Sclerotinia sp, Fusarium Cladosporium Aspergillus Mucor A...
