Summary: | Novel and potential antimicrobial compounds are essential to tackle the frequently emerging multidrug-resistant pathogens and also to develop environment friendly agricultural practices. In the current study, endophytic actinomycetes from rhizome of
Zingiber officinale
were explored in terms of its diversity and bioactive properties. Fourteen different organisms were isolated, identified and screened for activity against
Pythium myriotylum
and human clinical pathogens. Among these,
Nocardiopsis
sp. ZoA1 was found to have highest inhibition with excellent antibacterial effects compared to standard antibiotics. Remarkable antibiofilm property was also shown by the extract of ZoA1. Its antifungal activity against
Pythium
and other common phytopathogens was also found to be promising as confirmed by scanning electron microscopic analysis. By PCR-based sequence analysis of
phz
E gene, the organism was confirmed for the genetic basis of phenazine biosynthesis. Further GC–MS analysis of
Nocardiopsis
sp. revealed the presence of various compounds including Phenol, 2,4-bis (1,1-dimethylethyl) and trans cinnamic acid which can have significant role in the observed result. The current study is the first report on endophytic
Nocardiopsis
sp. from ginger with promising applications. In vivo treatment of
Nocardiopsis
sp. on ginger rhizome has revealed its inhibition towards the colonization of
P. myriotylum
which makes the study to have promises to manage the severe diseases in ginger like rhizome rot. |
