Lactic acid bacteria have stringent nutritional requirements. A lack of suitable nutrients can delay or prevent the onset of MLF. This work evaluated the composition of various nutrient formulations intended for bacteria, as well as their effect on bacterial viability. The analysis of elements, amino acids and vitamins revealed significant variations among these products and their effect on bacterial viability was strain dependent. A correlation between the vitamin B5 content in one nutrient and its effect on the viability of three bacterial strains could be established. The results also highlight the importance of proper storage conditions of nutrients on the concentration of vitamins that are essential for wine bacteria.
