Abstract
Lactic acid bacteria (LAB), isolated from milk and yoghurt, were tested for their efficacy against some phytopathogenic fungi under in vitro and in vivo tests. Fusarium oxysporum, one of most important pathogenic fungi invade tomato plants, was chosen to evaluate the effectiveness of LAB as a biocontrol agent under in vivo tests. Culture broth of LAB was applied as seed treatment or soil drench. The protective effect of LAB significantly increased after challenging inoculation by F. oxysporem, especially when LAB were applied as seed treatment; the number of roots increased by 216, 311, and 358% over control with LB-1, LB-4, and LB-5, respectively, whereas the increment was 169, 163, and 181% for soil drench. Interestingly, when LAB were applied as seed treatment, in soil infested with F.oxysporum, the total fresh weight of tomato plants increased by 348, 260, and 390% with LB-1, LB-3, LB-5, respectively, whereas the increment was 268, 427, and 393% with LB-1, LB-4, and LB-5, respectively, for soil drench. Overall, while previous reports of antifungal activity by LAB under in vitro tests are scarce, we have demonstrated for the first time the capability of LAB to act as plant growth promoting bacteria and biocontrol agent against some phytopathogenic fungi under in vivo tests.
