Bacteria-mediated plant growth promotion is a
well-established and complex phenomenon that is often
achieved by the activities of more than one plant growthpromoting (PGP) trait, which may not always be present in a
single organism. Biofilms developed using a combination of
two organisms with useful plant growth-promoting rhizobacteria (PGPR) traits may provide a definite advantage. In
this context, in vitro studies were conducted evaluating the
PGP traits of novel biofilms developed using Trichoderma
as matrix and agriculturally important bacteria (Azotobacter
chroococcum, Pseudomonas fluorescens and Bacillus subtilis) as partners. Such biofilms exhibited higher values for
various biochemical attributes as compared to the individual
organisms and dual cultures. Trichoderma–Bacillus and
Trichoderma–Pseudomonas biofilms exhibited enhanced
antifungal activity, ammonia, indole acetic acid (IAA) and
siderophore production, as compared to the other treatments. Trichoderma–Azotobacter biofilm recorded the highest nitrogenase activity and 1-aminocyclopropane-1-
carboxylic (ACC) deaminase activity. The synergism in
terms of the PGP traits in the biofilms revealed their promise
as superior PGP inoculants.
