Biotechnology and the potential of rhizosphere microorganisms in agricultural practices

Abstract

Objective: A brief introspective regarding biotechnological management of microorganisms from rhizosphere, its implementation in bioprocesses and its practical application in  field.

Design/methodology/approach: Bibliographic review regarding the beneficial effects of Arbuscular Mycorrhizal Fungi (AMF) and Plant Growth Promoting Bacteria (PGPR), with application in bioformulations.

Results: There are numerous documented applications of AMF and BPCV, both on laboratory and industrial scale for bioformulations production, with the aim of improving crop yield, providing resistance against abiotic stress and against pests. Non-conventional uses are also shown in areas other than agriculture.

Limitations on study/implications: AMF and PGPB are widely recognized in agriculture due to inherent ability to compete in harsh conditions within ecosystems, metabolism versatility and production of secondary metabolites that allow beneficial interactions with plants and other microorganisms. However, industrial production of AMF presents challenges because of their obligate biotrophs condition and a lack of compatibility with traditional bioprocesses.

Findings/conclusions: It is important that knowledge generated throughout rhizosphere research may be applied industrially, so its use shall be extended in agriculture.
