ABSTRACT

The present study was carried out to study the inhibitory effect of Lactobacillus plantarum isolated from different vegetables and leaf surfaces on fungal pathogens. Inhibitory activity of L. plantarum against Aspergillus flavus and Aspergills niger was studied by growing the fungal cultures singly and in association with L. plantarum and the fresh weight and dry weight of the mycelium and percent inhibition was recorded. L. plantarum isolate from Coriander showed maximum inhibition in case of A. flavus and the isolate from Cauliflower showed maximum inhibition in case of A. niger. The inhibitory activity varied among the L. plantarum. These results suggest that the inhibitory activity to fungal pathogens varied among the L. plantarum isolated from different vegetables and leaf surfaces.
