Objective:
To test a sample of laboratory prepared bacteria and categorise it according to Christian's gram positive and gram negative classes and also by viewing it under a high powered microscope and oil immersions; classify its shape and note any special characteristics.

…showed last 75 words of 819 total…Gram Positive bacteria.
Recommendation:
It is recommended that the same sample be tested again for de-coloration; focusing on de-coloration speed. If the de-coloration is fast then the sample is definitely gram negative, slow de-coloration would tell us it is gram positive.
For future samples it would be recommended to keep the bacteria sample for this specific test for only 16 hours as recommended to avoid the presence of old cultures which are anomalous to this test.
