ABSTRACT
Cadmium (Cd) contamination in soil is an environmental problem that can reduce soil quality, inhibit plant growth, and increase the risk of heavy metal accumulation in the food chain. This study aimed to evaluate the potential of Saccharomyces cerevisiae for reducing Cd concentration in contaminated soil and to determine its effect on the growth of tomato (Solanum lycopersicum L.). A completely randomized design with five treatments and three replications was employed, consisting of fertile soil as a positive control (P1), Cd-contaminated soil without bioremediation as a negative control (P2), and Cd-contaminated soil treated with S. cerevisiae at 5 mL (P3), 10 mL (P4), and 20 mL (P5). Soil Cd concentration, plant Cd concentration, plant height, number of leaves, and fresh weight were evaluated after four weeks. The results showed that the application of S. cerevisiae reduced Cd concentration in both soil and tomato plants while improving plant growth. The highest application rate (P5) produced the lowest Cd concentration in soil (0.05 mg/kg) and plant tissues (0.0002 mg/kg), compared with the untreated contaminated soil (0.14 mg/kg and 0.0012 mg/kg, respectively). The same treatment also resulted in the greatest plant height (26.30 cm), number of leaves (21 leaves), and fresh weight (11.53 g). These findings indicate that S. cerevisiae effectively reduced Cd availability in contaminated soil and enhanced tomato growth, suggesting its potential as an environmentally friendly bioremediation agent for Cd-contaminated agricultural soils.
