| Abstract | ||||
| Twelve bacterial colonies were isolated from five different tomato seedlings, long bacillus strains yielded results by possessing genes for the production of ribosomal lipopeptides. The strains were given laboratory names with the name BMG 100, 101 and 102 suggesting the strong possibilities of belonging to the three Bacillus species of Bacillus subtilis. It was found that all isolates had the ability to produce lipopeptides except for the third BMG 102 isolation, which did not show any production. Various levels of volumetric oxygen transmission have been used as indicators of productivity. Three different production systems were applied at the oxygen transfer levels. The antibacterial and antifungal effects of the three bacterial extracts from different production systems were examined against the following bacterial and fungal strains-Erwinia amylovora - Ralstonia solanacearum and Aspergillus niger, Phanerochaete chrysosporium -Alternaria alternata andPseudomonas syringae Which showed complete inhibition, and these results indicate the possibility of using lipopeptides in biological control. Attention should also be paid to studying the results related to production methods and quality, as this affects the efficacy of lipopeptides against the target pathogen. | ||||
