MBC: microbial biomass carbon, FDA: fluroscein diacetate activity, DHA: dehydrogenase activity, AcP: acid phosphatase and AkP: alkaline phosphatase ns: non-significant. Similar alphabets corresponding to different numbers represent treatments which do not have significantly variance analyzed at 5% level of significance.
