I got the Pichia strain from our culture bank, and revived them in YPD. The culture showed turbidity. Now, I need to confirm that my culture have the same strain or any contamination?
The easiest is to start from an isolated clone and to check its phenotype according to the strain genotype (auxotrophy markers and antibiotics resistance/sensitivity).
Hello, first use solid media and see any difference in colony morphology after growth. If you have the ability to make a microscope just use it to see the stains which are nicely visible under phase contrast microscopy if any bacterial contamination you can easily detect it.
