Occurrence of Metallo-beta-lactamase in Multidrug Resistant Escherichia coli Isolated from Donkey Slaughter Market

Ugbo E. N*, Ugbo A. I, Agumah B. N, Nwojiji E. C, Ewah C. M, Ogbonna I. P, Ekpono C. U.

Animals used in food production have been identified as one of the major primary sources of antibiotic resistant pathogenic bacteria within the Enterobacteriaceae family. The Escherichia coli harboring metallo-β-lactamases (MBLs) is a serious threat to global health. This study was aimed at the occurrences of metallo-beta-lactamase in multidrug resistance Escherichia coli isolated from donkey slau...

Induced Fermentation for the Production of Virgin Coconut Oil (VCO) Using Bacillus cereus Strain ST06 (MH475925.1) and Bacillus velezensis Strain Bv1-4 (OQ787546.1)

Adedayo M.R*, Kolawole W. O., Ajiboye, A.E

The use of bacteria in fermentations to produce functional foods has greatly increased in recent years due to the numerous associated benefits. Moreover, the increased demand for the production of virgin coconut oil (VCO) at household and industrial level as well as the need to overcome the problem of contamination associated with spontaneous fermentation justifies this research. Matured Coconut f...

Probiotics Potential of Bacteria Associated with Fermented Unripe Plantain (Musa paradisiaca) Juice Sold in Orieugba Market Umuahia, Nigeria

Appeh O. G*, Ugbogu O. C.

Probiotics are live microorganisms that when administered in adequate amounts, confer a health benefit on the host. They are naturally present in fermented foods, may be added to other food products and are available as dietary supplement. This study was aimed to determine probiotics potentials of bacteria associated with fermented unripe plantain (Musa paradisiaca) juice. The physico-chemical ana...

Isolation and Characterization of Probiotic Lactic Acid Bacteria from Fermented Foods Using Conventional and Molecular Methods

Hassan M. R*, Saleh, A. A., Muhhammad B. T.

The study aimed to isolate and characterize probiotic lactic acid bacteria from fermented foods using conventional and molecular methods. The isolation was done using De Man, Rogosa, and Sharpe (MRS) agar using standard procedure and standard biochemical tests for the identification of lactic acid bacteria. The isolates were confirmed using polymerase chain reaction (PCR), sequence analysis and co...

Microbial, Proximate and Sensory Evaluation of Bread Produced from a Blend of Wheat and Corn Flour

Mbachu A. E*, Otuya W. A, Mbachu N. A

Wheat flour, which is the major raw material used in baking bread, is being imported in Nigeria and other countries where cultivation of wheat is hampered by unfavourable climate. This has necessitated the rising cost of bread beyond the reach of the poor in Nigeria. This study was aimed at assessing the quality of bread produced from a blend of wheat and corn flour. Composite breads were produced...
