Soil enzymes in contaminated soils (CS), amended with bacteria inoculum B. Cereus (BI), biochar (BC), and biochar + bacteria inoculum (BC + BI).

Soil enzymes (mg g− 1 24 h− 1)	CS	CS + BI	CS + BC	CS + BC + BI
Alkaline Phosphatase	4.6 ± 0.93 c	6.12 ± 0.79 b	6.31 ± 0.86 b	8.13 ± 1.01 a
Catalase	3.4 ± 0.03 bc	4.9 ± 0.06 b	4.5 ± 0.21c	6.5 ± 0.41 a
Urease	54.5 ± 0.98 c	77.9 ± 1.33 b	77.9 ± 1.13 b	218.6 ± 1.95 a
Dehydrogenase	0.45 ± 0.02bc	0.47 ± 0.02 b	0.45 ± 0.01b	0.35 ± 0.03 a

All measurements are taken at pH = 7. Values are the mean ± SE where n = 5. Different latter indicates difference at significance level using one-way Annova (Duncan) test (op < 0.05), and n = 4 ± SD. Where ^a is highly signficant ^b is significant and ^c is lower significantly different.
