About the Author
I am a graduate of Abubakar Tafawa Balewa University, Bauchi in Nigeria with a Bachelor of Technology degree in applied
microbiology, then an M.Sc. in Medical microbiology.

I am currently a lecturer and researcher with the said university. My research interest spans through the use of medicinal plant antimicrobials, anaerobic digestion with focus on sanitation, mushroon cultivation on agricultural wastes. I have a series of publications in all these areas.

I was borned a Cameroonian in the highlands of Bamenda.

Abstract The study details the result of a preliminary investigation on the coagulative and disinfective ability of seeds of Moringa oleifera, Jatropha curcas seeds, calyx of Hibiscus sabdarifa, sclerotium of Pleurotus tuberregium and Alum on wastewater samples from Yelwa settlement in Bauchi, Nigeria. Varying weights (0.5 to 59) of dried pulverized plant materials and Alum were placed in 200 mls each of the three-wastewater samples and left for 24 hours.  The results showed well above 90% reduction in bacterial load of the water samples by Moringa oleifera.  All the plant materials exhibited appreciable coagulative effect comparable to Alum.  Moringa oleifera seeds, Jatropha curcas seeds and Hibiscus sabdarifa calyx reduced the bacterial load drastically and inhibited Escherichia coli in vitro using the Agar diffusion method. The turbidity of both plant  Alum treated water samples drastically reduced.  The PH of Alum treated water was observed to decrease from neutral to acidic as opposed to a constant PH of 7.0 for both plant treated and untreated wastewater samples.  This preliminary report does not only suggest an alternative and possibly cheaper water purification opportunity for rural communities in third world countries but also suggest good starting materials for the synthesis of environment friendly natural coagulant and disinfectants.

Key words: Coagulative, Disinfective, Total aerobic mesophilic Counts, E. coli counts, Coliforms counts, Waste water, Medicinal plants, Mushroom sclerotium.
