Studies on Optimal Production of Keratinase by Bacillus cereus 35 Isolated from Feather Dump Sites in Enugu Metropolis, Enugu State, Nigeria

Ezeme-Nwafor, A. C*, George-Okafor, Uzoamaka Ogechi

Chicken feathers are usually difficult to degrade due to their hard keratinous nature. Their inadequate methods of disposal have brought about environmental problems and loss of possible essential amino acids. Keratinases produced by bacteria including Bacillus spp. could be used to alleviate most of the disposal problems hence, the need to optimize the submerged fermentation process for maximum k...

Occurrence and Antibiotic Susceptibility of Aeromonas species from Piggery Farms in Ebonyi State, Nigeria

Onuoha, S .C*, Eronmosele, B. O, Okoh, F.N, Okafor, C. O, Onwere, C.C, Ovia, K. N

Aeromonas has been implicated as the most common bacterial disease in farm animals. In Ebonyi State, Nigeria, these infections and their adverse effects on public health have not been well investigated. The study detects the presence of Aeromonas species from Piggery Farms and determines the antibiotic resistance profile of the isolates. A total of 50 fresh Pig feacal samples were randomly collect...

Biosorption of Crystal Violet Dye Solution by Aspergillus striatus, Bacillus megaterium, Chlorella vulgaris and Fusarium equiseti

Sani, Z.M*, Garba, I., Maigari, A.K., Umar, S., Kabir, A, Bala, I

Crystal violet is a synthetic triphenylmethane dye that serves as a biological stain which can also be used in dyeing textile materials. It is toxic and remains in the environment for longer periods, as such needs to be treated before discharge. This study was carried out to assess the biosorption potentials of Aspergillus striatus, Bacillus megaterium, Chlorella vulgaris and Fusarium equiseti on ...

Mycoremediation of Spent Lubricating Oil Contaminated Soil Using Pleurotus ostreatus

Maduwuba, M. C*

This study was conducted to evaluate the remediation capability of Pleurotus ostreatus on spent lubricating oil polluted soil. Twenty percent (v/w) lubricating oil was spiked into 100 g of garden soil, inoculated with P. ostreatus pre-grown with sawdust as a substrate. The changes in pH, moisture content, total petroleum hydrocarbon, percentage total organic carbon, nitrate and phosphate concentra...

Antibacterial Activity of Black Soap (Sabulun Salo) against Methicillin Resistant Staphylococcus aureus (MRSA) and Coagulase Negative Staphylococi (CoNS) Isolated from Skin and Soft Tissue Infections

Yakubu, H., Aminu, B.M., Aminu, A. I*

Methicillin resistant Staphylococcus aureus (MRSA) and Coagulase negative Staphylococci (CoNS) especially Staphylococcus epidermidis cause skin and soft tissue infections that are often challenging to treat. This study determines the antibacterial activity of locally made black soap on MRSA and CoNS isolated from skin and soft tissue infections. Two hundred (200) swab samples were collected from p...
