The increase use of synthetic enzymes in different industries has resulted in toxicity and decrease
in specificity. This menace has necessitated for an alternative source of enzymes which could be
friendly to both man and environment. This study was carried out to evaluate enzyme-producing
potentials of bacterial species isolated from goat dung-contaminated soil at Awka South Local
Government Area, Anambra State, Nigeria. Forty goat (40) droppings were collected from four
different communities that were investigated (Umuawulu, Nibo, Mbaukwu, and Nise) at the
LGA. The presence of bacteria in the goat dung-contaminated soil was evaluated using standard
microbiological technique. The bacterial isolates were identified using cultural, morphological, and biochemical features. The digestive enzymes (amylases, lipases, and cellulases)-producing
potentials of the bacterial isolates were investigated using standard microbiological techniques. The result revealed that all the bacterial isolates produced lipases, cellulases, and amylases, but
the quantity of the enzymes varied as revealed in the enzyme activity index (EAI)S. The highest
amylase was produced by Klebsiella species (75%) while the highest lipase was produced by
Bacillus species (60%) and the highest cellulase was also produced by Klebsiella species
(84.20%). Statistically, there was a significant (P < 0.05) difference in the quantity of enzymes
produced by the bacterial isolates. This study has shown that bacterial species isolated from goat
dung sites are capable of producing digestive enzymes, which are highly essential in different
industries and biotechnology
