Title

Using cheap by-products of food industry for cultivation of Paenibacillus polymyxa strain N179

Pages

  93-101

Abstract

 In current research Paenibacillus polymyxa strain N179 was selected based on its previous performance in greenhouse and field condition, and cheap by-products of food industry was used to introduce a best medium for its high quality and low-cost cultivation. The growth rate of this bacterium in various media was significantly different as the proliferation of it in medium M1 (with beet molasses and ammonium sulfate) was 17. 3 percent grater than the medium M5. addition, antagonistic activity of cells from various media either in-vitro or in greenhouse condition was significantly different. The cells from M4 (10 g date pomace, 4 g sesame press cake) and M10 (4 g sesame press cake, 5 g starch) have shown highest inhibition against Rhizoctonia solani fungus. The resistance of cells from media against formulation process and viability during preservation period was assessed and it was found that cells from LB, M9, M7, and M2 media were the most resistant ones during preservation period as the difference of population of formulation made from M7 medium was 26 percent greater than the one from medium M1 (worst performance). Moreover, efficacy of prepared formulations was assessed after three months in greenhouse condition and it was found that formulations made from M5 and LB were the most effective ones in controlling the disease and the disease index was 40 and 50 percent, respectively, lower than the infected control. However, considering all of the results from growth rate, shelf life, inhibitory effect, M9 was shown the best performance.
