“…However, most approaches for using PGPB have relied on application of single bacterial strains that may partially account for the reported inconsistencies in field, since a single biological agent is not likely to be active in all soil environments. Logically, potentials for improving plant yields by combining these PGPB by co-inoculation have also been a subject of several investigations for more than a decade (Felici et al 2008;Cong et al 2009). Inoculation of Azospirillum the well-known PGPB is more successful and more profitable when it is applied along with other groups of microorganisms (see Bashan et al 2004).…”

The present greenhouse study was undertaken to evaluate the effects of co-inoculating methylotrophic Methylobacterium oryzae CBMB20 along with nitrogen-fixing Azospirillum brasilense CW903 or a phosphate solubilizing bacterium Burkholderia pyrrocinia CBPB-HOD on the growth and nutrient uptake of tomato, red pepper and rice. Seed inoculation and soil/foliar application of the bacterial strains alone or under dual inoculation increased the plant growth in terms of shoot or root length and increased the nutrient uptake in the plants studied compared to uninoculated control plants. Co-inoculation of M. oryzae CBMB20 with A. brasilense CW903 or B. pyrrocinia CBPB-HOD improved the N and P concentration of plants, while the results varied among the plant species tested. Also, co-inoculation of the bacterial strains increased the activity of nitrogenase, urease and phosphatase enzymes in soil when compared to uninoculated control or individual inoculations. Though the inoculation effects were analyzed at an early stage of plant growth, the results conclusively suggest that M. oryzae being compatible with other microorganisms in the rhizosphere can potentially be used as individual inoculant or co-inoculated with other plant growth promoting bacteria to increase the production in sustainable agricultural systems.

“…were tested as inoculants of leguminous trees to revegetate part of the Sonoran Desert . Particularly, A. brasilense, a plant growth-promoting bacterium (PGPB), has been reported several times to alleviate abiotic stress and promote plant growth, either alone or with microalgae (Gonzalez and Bashan 2000;de-Bashan et al 2008a;Bashan and de-Bashan 2010) especially in maize, wheat, or rice (Rodríguez et al 2006;Trivedi and Pandey 2008;Cong et al 2009;Rodríguez-Salazar et al 2009;Bashan and de-Bashan 2010). Even though the exact mechanisms of action are unknown, the fact is that this PGPB significantly increases and improves the plant's root system by making nutrients available, inducing proton release from root cells membranes or by phytohormone delivery which stimulates plant growth .…”

Wild-type Azospirillum brasilense Cd, mutant Azospirillum brasilense Cd transformed bacteria with a plasmid harboring a trehalose biosynthesis gene fusion from Saccharomyces cerevisiae, and Chlorella vulgaris were used as immobilized inoculants for tomato seedlings growing in hydroponic media prepared with different proportions of NaCl. Stem and main root length, number and length of leaves, and secondary roots of seedlings were measured and compared between treatments as indicator of biomass production. A positive effect in tomato seedlings was observed when cocultured with Azospirillum (transformed and wild type) and C. vulgaris. Those seedlings growing with wild-type Azospirillum and Chlorella showed longer stems for lower salinities. Conversely, longer stems were observed when transformed Azospirillum and C. vulgaris were used as inoculant in the highest salinity tested (250 mM NaCl).

“…Adhesives include gum arabic (Wani et al 2007), carboxy methyl cellulose (Viji et al 2003), sucrose solutions (Cong et al 2009), vegetable oils (Bashan et al 2002), as well as any non-toxic commercial adhesive to the bacteria and seeds. A second role of an adhesive is to prevent the inoculant (either dry inoculant as powder or wet inoculant once the moisture evaporates) from dislodging during sowing with the seeding equipment, especially the powderedtype when applied with air-seeders.…”

“…For the large majority of developing countries, inoculant technology, especially with PGPB, has no or little impact on productivity of family farms because inoculants are not used, are of poor quality, or are homemade (Bashan 1998). Surprisingly, and probably as a result of the potential for cheaper production of inoculants by small companies, compared to expensive chemical fertilizers and pesticides, many practical studies of numerous crops were performed in developing countries, such as the Indian subcontinent (Johri et al 2003), Vietnam (Cong et al 2009), and on cereals and legumes in Latin America, mainly in Argentina and Mexico (Diaz-Zorita and Fernandez-Canigia 2009;Hartmann and Bashan 2009;Fuentes-Ramirez and Caballero-Mellado 2005) and in Africa (Atieno et al 2012;Mathu et al 2012).…”

Background Inoculation of plants to enhance yield of crops and performance of other plants is a century old, proven technology for rhizobia and a newer venue for plant growth-promoting bacteria and other plant symbionts. The two main aspects dominating the success of inoculation are the effectiveness of the bacterial isolate and the proper application technology. Scope An assessment of practical aspects of bacterial inoculants for contemporary agriculture and environmental restoration is critically evaluated from the point of view of their current technological status, current applications, and future use. This is done because there are windows of opportunity for new developments in applied research using renewable, non-contaminated natural resources and new venues for research. Special emphasis is given to formulations and polymeric carriers. This review concentrates on practical aspect of inoculation technology dating from 1998 to 2013. Earlier publications are mentioned only for clarification of a specific point. Conclusions This review discusses characteristics of a carrier for inoculants, formulations of inoculants including liquid, organic, inorganic, polymeric, and encapsulated formulations. Technical aspects include inoculation techniques (soil and seed application), mass culture production, bulk sterilization, seed coating, shelf-life, and effect of moisture. Future research venues needed are noted.
