Bacteria Changing Colour
Posted 20 July 2009 - 11:09 PM
i have a bacteria that is gram negative cocci. special thing about it is that it changes colour with growth, means growing freshly on nutrient agar its Red and then turns Cream colour with time, but again it is Red at the outer ends of colony means where it has access to media and growing fresh there,
So can anybody tell me more about this....

In any case, pigmentation is not an end point in identification - can you not complete that?
