The ability of some microorganisms to stimulate the growth and development of plants is known. However, the use of residual yeast from the artisanal brewing industry as plant growth promoting microorganisms (PGPM) has been briefly studied. The aim of this work was to characterize and analyze the use of residual yeast from the brewing industry in hydroponic vegetable crops. We evaluated the effects of yeast addition on plant growth of Eruca vesicaria, Arabidopsis thaliana y Lactuca sativa with this technique. A significant increase in the principal root length was observed after the treatment with the yeast suspensions in A. thaliana and E. vesicaria grown relative to the control (SN 4.28 ± 0.15, S05 7.30 ± 0.29; SN 39.68 ± 2.20, S05 57.37 ± 2.80, respectively). In floating hydroponic systems, yeast inoculation to the hydroponic solution increased the root area of L. sativa by 30 % in relation to the control. Our results confirm that Saccharomyces cerevisiae strain J14 from the brewing industry may confer benefits in hydroponics crops with positive effects on root growth. These results validate the potential application of S. cerevisiae strain J14 in plant cultivation in hydroponic as a biotechnological tool.
