ABSTRACT
Secondary metabolites are the special chemicals that organisms make for their own purposes. They are not
needed for their basic functions, but they have many uses in their interactions with the environment. They can
protect themselves, communicate with others, compete with rivals, and cooperate with partners. Mycorrhizal
Helper Bacteria (MHBs) are bacteria that enhance the plant-fungi partnership by supporting their growth,
nutrition, and defense, and by modifying their production and use of secondary metabolites, which help them
interact with the environment. In this study, morphological characterization and isolation were carried out
following the serial dilution method, and checked the antimicrobial activity of isolated strains in biological
screening. The best strains were selected for secondary metabolite production through shaking fermentation
culture techniques; FTIR (Fourier transform infrared) spectroscopy and grams’ staining were also carried
out. Strain PW 2-3-1 showed the highest antimicrobial activity, whereas strain AP 10-2-4 showed the least
against four bacterial strains, viz; Bacillus meurellus, Bacillus subtilis, Acinetobacter rhizosphaerae, and
Escherichia coli. FTIR spectrum analysis showed the presence of C–H and C–O stretches with wavenumbers
ranging from 500-3500 of antibiotic nature. The application of Mycorrhization Helper Bacteria can be
an encouraging method to achieve successful reforestation. It has been additionally recommended that
Mycorrhization Helper Bacteria could detoxify the impacts of parasitic metabolites.
