In this experiment, mud samples were collected at Sungai Siput, Simpang Empat, Alor Gajah, Melaka (2.4341395,102.1831934).
The mud samples were closed tightly with plastic cover to avoid contamination during handling the sample to lab.
We mixed the mud with shredded newspapers to supply the microorganism with carbon. We also mixed it with egg yolk and shell to provide sulphur to the mud.
Then we separated it into four containers. Each container was labelled with blank, heavy metal, fertilizer and cooking oil.
Finally, all containers were closed with plastic and placed at open area to expose the containers to the sunlight.
Please explain more clearly what type of fertiliser, heavy metal and oil did you add. How much did you add?
ReplyDeleteIn a experiment designed for measuring the activity of sulfur oxidising bacteria in soil, how would you prove the that your activity measurement was due to biological activity?? Please share...your views
