Baker's yeast. Some biochemical aspects and their influence in biotransformations.

Baker's yeast is becoming an important reagent for organic synthesis. However, on many occasions, there are problems with the experimental reproducibility, which in general is the result of the different origins of baker's yeasts. In order to explain these differences, NAD (P)+ reduction inside intact living cells from different strains was measured. The method can select cells with better reduction power in a short period of time.
