The two strains a and b are tested for being auxotrophic for the following nutritional mutations: pyridoxine (pdx), biotin (bio), methionine (met), adenine (ade), and para-aminobenzoic acid (pab). Growth is indicated by ( + ) and lack of growth by ( - ). From these tests, what is genotype of strain a and b respectively (+ indicate prototroph while other auxotroph)?
