Interpretation:
To study the role of microorganisms behind their bioenhancing, biocontrol properties, their enzymatic potential, and characterization of high
performing microbial isolates on molecular basis.

Dominant culturable microbes including bacteria and
fungi were isolated from biodynamic preparations and screened on the
basis of plant-growth promoting (PGP) activities viz., ammonia
production, phosphate solubilization, siderophore production,
hydrogen cyanide production, seed germination efficacy and
biocontrol properties. The dominant and effective microorganisms
were screened for enzymes activities viz., pectinase, cellulase and
amylase. The selected bacterial and fungal isolates, exhibiting higher
enzyme activities, were subjected to molecular characterization.
Out of 68 bacterial and 25 fungal isolates from 8 biodynamic
preparations (BD 500 - BD 507), 15 bacterial isolates exhibited high
plant growth promoting activities while 10 bacterial isolates exhibited
biocontrol activity against pathogens. Bacillus licheniformis isolated
-1 -1 from BD 504, expressed high pectinase (2.595 U ml min ), cellulase
-1 -1 -1 -1 (0.308 U ml min ) and amylase (0.418 U ml min ) activities. Fungal
isolates with high enzymatic activities, were isolated from BD 500, 503
and 506, respectively.

Microorganism isolates from biodynamic preparations
possessed strong plant growth promoting, biocontrol and enzymatic
properties, which might be responsible for the efficacy of organic
preparations under field conditions.
