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,
