“…Biofilm production is already obtained for different industrial applications (e.g., wastewater treatment, production of chemical compounds) [113]. Two types of biofilms are employed in that case: biofilms growing onto inert supports (charcoal, resin, concrete, clay brick, sand particles) and biofilms that are formed as a result of aggregate formation.…”

“…Another interesting new technology is proposing the exploitation of the natural production of bacterial biofilms as a possible carrier, and not only for the production of the inoculum, of defined bacterial or fungi-bacteria consortia. Biofilm production is already obtained for different industrial applications (e.g., wastewater treatment, production of chemical compounds) [ 113 ]. Two types of biofilms are employed in that case: biofilms growing onto inert supports (charcoal, resin, concrete, clay brick, sand particles) and biofilms that are formed as a result of aggregate formation.…”

“…In the first case, biofilms grow all around the particles, and the size of the biofilm particles grows with time usually to several mm in diameter. Biofilm formed by aggregation is called granular biofilm; granule formation may take from several weeks to several months [ 113 ].…”

The increasing need for environmentaly friendly agricultural practices is driving the use of fertilizers based on beneficial microorganisms. The latter belong to a wide array of genera, classes, and phyla, ranging from bacteria to yeasts and fungi, which can support plant nutrition with different mechanisms. Moreover, studies on the interactions between plant, soil, and the different microorganisms are shedding light on their interrelationships thus providing new possible ways to exploit them for agricultural purposes. However, even though the inoculation of plants with these microorganisms is a well-known practice, the formulation of inocula with a reliable and consistent effect under field conditions is still a bottleneck for their wider use. The choice of the technology for inocula production and of the carrier for the formulation is key to their successful application. This paper focuses on how inoculation issues can be approached to improve the performance of beneficial microorganisms used as a tool for enhancing plant growth and yield.

“…The final product of the process is almost spherical particles that form a free-flowing powder which can be suspended in water. The possibilities of the PGSS process have already successfully been demonstrated for several solids and liquids (Cocero et al, 2009 (Qureshi et al, 2005). Application of a biofilmed inoculant containing a fungalrhizobia consortium significantly increased N 2 fixation in soybean compared to a traditional rhizobium inoculant (Jayasinghearachchi and Seneviratne, 2004).…”

Plant growth promoting rhizobacteria are the soil bacteria inhabiting around/on the root surface and are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory chemicals in the vicinity of rhizosphere. There has been much research interest in PGPB and there is now an increasing number of PGPB being commercialized for various crops. Today a lot of efforts have been made for searching and investigating the PGPB and their mode of action, so that they can be exploited commercially as biofertilizers. Because of the various challenges faced in screening, formulation, and application, PGPB have yet to fulfill their promise and potential as commercial inoculants. Recent progress in our understanding of their diversity, colonization ability, mechanisms of action, formulation, and application should facilitate their development as reliable components in the management of sustainable agricultural systems. Several reviews have discussed specific aspects of PGPB as bioinoculants. We have tried to critically evaluate the current status of bacterial inoculants for contemporary agriculture in developed and developing countries. This review focuses on some important information regarding the biofertilizing potential of some important group of microbes, their formulations, their application for the development of sustainable technology, scope of improvement by genetic engineering, steps to be undertaken for their commercialization and their future prospects.

“…Moreover, fungal BfRs facilitate reuse of fungal biomass for long-term production and downstream processing operations. The concept of a BfR, mainly used for environmental applications, has been expanded in the field of microbial catalysis for the production of various metabolites, ranging from medium (organic acids, volatile compounds and enzymes) to high-added-value molecules (antibiotics and heterologous proteins) (Cheng et al 2010;Qureshi et al 2005). In these bioprocesses, the specific area (m 2 /m 3 ) provided by the solid support to allow biofilm growth must be as high as possible in order to maximize productivity of the bioreactor.…”
