Question

I have one yeast isolate producing bright red colony plz help which are the possible species?

Answer 1

What is the genotype of the yeast and what type of media are you growing them on?

Yeast carrying mutations of the ade1 or ade2 gene will produce a red colour if not supplied with enough Adenine in the medium.

See: http://www.biologytools.net/protocols/ye...

Edit: I am assuming that you have already ruled out bacterial contamination by colony morphology (yeast and bacterial colonies look very different) or by a quick peek down the microscope.

Answer 2

  The red bacteria is likely Serentia Marcesense

Answer 3

I'd go with the Adenine answer (although I guess it could be red bacteria).
