Microbiological and Toxicological Assessment of Pharmaceutical Wastewater from the Lagos Megacity, Nigeria

Table 3

Enzymatic assay of bacterial isolates from pharmaceutical wastewater.

Isolates/enzyme	Amylase	Protease	Phospholipase
ME1	ND	ND	ND
ME2	7++	ND	ND
ME3	ND	ND	ND
ME4	11+++	8++	ND
ME5	(14)+++	ND	ND
ME6	ND	ND	ND
ME7	6+	ND	+++

Degree of enzymatic activity: + = low (≤2 mm), ++ = moderate (>2–8 mm), +++ = high (>8 mm), and ND = nondetectable.
