    Abstract

    There is a substantial and increasing effort in industrial microbiology and biotechnology to develop microbial inoculants as a means to improve the sustainability and profitability of rural activities whilst increasing productivity. Inoculants are being developed for use as microbial biofertilizers, biocontrol agents for weed suppression, biopesticides and bioremediation agents. All of these require the addition of microorganisms to complex microbial communities. Plant Growth Promoting Rhizosphere organisms (PGPRs) are good examples of microbes that might have important roles in agriculture. PGPRs inhabit plant root rhizospheres and can affect plant growth directly by nutrient solubilisation (P, Nand K) and production of plant growth regulators, and indirectly by suppression of plant pathogens by competition, release of antibiotics or siderophores.
