ABSTRACT

Tons of floral waste is generated every year from different religious places. Floral waste has tremendous and largely unexploited potential of being a potent antimicrobial source against pathogenic organisms. In the present study floral waste collected from religious places and utilized for preparation of hot and cold; alcoholic and petroleum ether extracts. These extracts were evaluated for their potential to inhibit growth of fungal phytopathogens isolated from various infected fruits, vegetables and seeds. Hot ethanolic extracts were found most potent among all and inhibited growth of Penicillium chrysogenum at 10mg/ml whereas Aspergillus niger, Aspergillus flavus, Curvularia sp., Fusarium sp. and Alternaria solani MTCC 2101 were inhibited at 20mg/ml concentration. Safety study with Lactobacillus curieae CCTCC M2011381 revealed that extracts do not have any adverse effects on gut beneficial bacteria at minimum inhibitory concentration against fungal pathogens. All extracts exhibited significant antioxidant activity at 0.1mg/ml concentration thus can be used against disorders resulting due to reactive oxygen species and oxidative stress. These extracts could be a promising and safe alternative of chemical fungicides to develop antifungal formulations and to prepare edible coating on fruits and vegetables to extend their shelf life by protecting them from phytopathogens.
