The Activities Of Some Microbial Isolates From Cassava Farm Soil To Produce Antibiotics
ABSTRACT
The lack of new
therapeutic options to replace many antimicrobial agents that are losing their
efficacy against resistant bacteria is a growing concern. The search for new
antimicrobials from rare andlor existing sources have thus become a worthwhile
effort in recent years. Soil samples collected from cassava farm land in
Umudike were studied in an effort to screen for novel antibiotics produced by
soil microbes. A total of 45 bacterial and 19 fungal isolates were successfully
obtained from the soil samples. Antibiotic activity screening using the paper
disc diffusion technique was used to evaluate the antagonistic potentials of
the isolates against ATCC Strains of bacteria including Staphylococcus aureus,
Salmonella typhi, Escherichia coli. Out of the 64 isolates, 6.25% (4/64) were
active against at least one of the test organisms with diameter zones of
clearing that ranged from 10.0mm to 17.0mm. Isolate Microccus spp exhibited the
strongest antibacterial activity against S. typhi and E. coil with diameter
zones of clearing of 17mm and 11.0mm respectively followed by Bacillus spp
which recorded a zone of inhibition of 14mm and 10mm against E. coil and S.
aureus respectively
