Topic: Pharmaceutical Microbiology


Pharmaceutical microbiology is a field of microbiology that sees to the development and use of microbial products and natural products from plants in effecting treatment of various diseases.

The aim is to obtain bioactive components of plant which can be deployed in tackling antimicrobial resistance problems in Nigeria and beyond. It involves using different methods in extracting bioactive compounds from plant materials and also assaying for their antimicrobial efficacies against several pathogens and especially multidrug resistant species. These assays include antimicrobial sensitivity testing, killing kinetics, mechanism of action of bioactive compounds, antioxidant determination etc.

Isolation of compounds that can be used to treat diseases and infections caused by resistant species effectively with very minimal or no toxic effects.

Enlightenment of the general populace on the use of herbal remedies in treating different diseases and infections based on determined and known dosages.

Current Research

Evaluation of the Effects of Collection Time, Drying Temperatures and Conditions on the Quantity of Bioactive Components and their Bioactivity

Research Details

There is the myth that plants do 'sleep' after sunset.

The aim of the research is to check the effect of time of collection of plant materials on their bioactivity, and quantity of bioactive compounds present in the various samples collected at different times of the day. Likewise, studies will be carried out on the effects of different drying conditions and temperatures on bioactive components and activity.

The objectives will be achieved using different drying equipment, bioactive components will be analysed using Gas Chromatography-Mass Spectrometry, Phytochemical screening and Sensitivity Test.

The research will reveal whether the collection times, drying conditions and temperatures actually affect the quantity of bioactive compounds present in plant material under processing which are responsible for bioactivity of the plant species.

The outcome of the research will adequately inform the society as to whether there is the best time to collect plant materials for optimal derivable medicinal values.
