CharonY Posted March 4, 2009 Share Posted March 4, 2009 What is the difference between the cell hull of a Gram-negative and a Gram-positive bacterium? Also this goes into the homework section. Link to comment Share on other sites More sharing options...
abacus49 Posted March 11, 2009 Share Posted March 11, 2009 I'm not sure if you are looking for a more detailed explanation or not but a gram positive bacteria will absorb india ink into it's cell wall whereas a gram negative will not. When one is trying to identify a bacteria culture on a slide the process is to dip the slide into the ink and then rinse it off. The bacteria will retain the dye or it wont and that is why they are referred to as positive or negative. Hope this helps and isn't too simplistic.
