Isolation and Identification of Non Dermatophytic Moulds from Different Air and Soil Samples from Cattle Markets in Abia and Imo State, Nigeria

Nwofor C. N*, Echeta, M. O, Onyenwe, N. E, Oyeka, Christie A

The prevalence of non-dermatophytic moulds from air and soil samples from six cattle markets in Abia and Imo state, Nigeria were carried out simultaneously. A total of 60 (sixty) samples of air and soil were analysed. The settlement plate technique, tube dilution method and hair baiting technique were evaluated for the air and soil for the presence of keratinophilic fungi. Different species of 13 ...

Molecular Characteristics, Antibiotic Sensitivity, and Substrate Specificity of Biosurfactant-Producing Bacterial Isolates from Crude Oil Spill Sites in Niger Delta: A Comprehensive Review

Emeanuru P. C*, Ogbulie J.N, Adieze I. E., Nwachukwu, I.N., Braide, Wesley, Nwosu C. J

The Niger Delta area, renowned for its biodiversity, has suffered severe environmental degradation due to crude oil spills resulting from oil exploration and exploitation activities. To address this, researchers have explored biosurfactant-producing bacteria as eco-friendly solutions for remediating polluted sites. Indigenous strains, such as Pseudomonas aeruginosa and Bacillus subtilis, have been...

Assessment of Electromagnetic Field on Bacteriological and Physicochemical Properties of Brewery Effluent from Ilesha

Balogun O. B*, Akinyosoye F. A, Arotupin Daniel Juwon

The present study was designed to enumerate and identify microorganisms and to determine physicochemical properties of industrial effluents. Samples were collected from four different industries in Oriade local government (Ilesha, Ikeji-Arakeji and Ipetu Ijesha). The Industrial effluent samples were subjected to microbiological and physicochemical analyses. Bacteria isolated from industrial efflue...

Screening and Identification of Biosurfactant-Producing Bactria from Crude Oil Contaminated Soil and Water in the Niger Delta Area, Nigeria

Emeanuru P. C*, Ogbulie J.N, Adieze, Ifechukwu E., Nwachukwu, I.N., Braide, Wesley

Crude oil pollution is sine qua non in oil exploration and exploitation activities. Biosurfactant increases bioavailability and help to enhance contact between the pollutants and the microorganisms and therefore facilitates uptake and degradation as well as amelioration (remediation) of hydrocarbon polluted environment. Biosurfactant is preferred to chemical surfactant in crude oil remediation. Th...

Degradation of Diesel by Staphylococcus sciuri Strain XB1 Isolated from a Dumpsite in Lagos State, Nigeria

Fashola, M. O.*, Opere, B. O., Dawodu T. B, Anagun O. S., Semako S. D, Obayori, O. S

Staphylococcus sciuri strain XB1, a diesel degrading bacterium, was isolated from Igando dumpsite by continuous enrichment technique on diesel mineral salt medium (MSM). The isolate was identified using cultural, morphological, biochemical characteristics and complemented with analytical profile index. The isolate is yellowish, Gram-positive cocci, catalase positive, oxidase and coagulase negative...

Microbiological Examination of Personal Effects of Undergraduate Students in Microbiology Laboratory

Ofon U. A.*, Okon, M. U, Udofia E. S., George M. U

Personal effects (PEs) including phones, laptops and bags globally are a necessary part of our everyday lives. These PEs are often carried or worn by individuals for numerous purposes, globally. However, the increasing risk of microbial contamination and the presence of antibiotic-resistant strains on these devices are of public health significance. Using standard microbiological procedures, this ...
