Abstract
The utilization of tofu wastewater and molasses as alternative media for the growth of Streptomyces sp. is expected to support the antagonistic activity of Streptomyces sp. against Fusarium sp. both in vitro and in vivo. This study was arranged using a non-factorial Completely Randomized Design (CRD). The results showed that the highest colony number was obtained in the combination medium of tofu wastewater and molasses, reaching 1.91 × 10⁹ CFU/ml at 48 hours of observation. Meanwhile, the lowest colony number was observed in the molasses medium (M2) at 24 hours of observation, amounting to 5.7 × 10⁸ CFU/ml, followed by the tofu wastewater medium (M1) at 72 hours of observation with 7.3 × 10⁸ CFU/ml. Tofu wastewater and molasses could be used as alternative media for the growth of Streptomyces sp., with the highest colony number obtained in M3 medium (combination of tofu wastewater and molasses). Streptomyces sp. propagated in the alternative media also showed inhibitory activity against Fusarium sp. in vitro, and was able to suppress the intensity of Fusarium wilt disease and enhance tomato plant growth in vivo compared to the control.
