“…Similarly, in previous studies, an association of maize plant with specific bacterial genera (Bacillus and Lysinibacillus) has been reported (Cavaglieri et al 2005;Vigliotta et al 2016). Further studies also showed that B. subtilis and L. fusiformis are present in soil ecosystem where they interact with plant roots and particularly in maize plant (Posada et al 2016;Singh et al 2013;Zhang et al 2016). Bacterial strains such as B. subtilis and L. fusiformis have already been reported as effective maize plant growth-promoting rhizobacteria through P-solubilization, and this activity was confirmed by the biochemical test in the present study (Chauhan et al 2016;Sgroy et al 2009).…”

Maize plant has an absolute requirement of nutrients (N, P, and K) for growth and development. The microbial application can facilitate in addressing limited access to chemical fertilizer concern. Moreover, biochar and phosphorus-solubilizing bacterial (PSB) community can contribute together in nutrient availability. Both have the P-supply potential to the soil, but their interaction has been tested less under semiarid climatic conditions. The purpose of the study was to evaluate the potential of biochemically tested promising PSB strains and biochar for maize plant growth and nutritional status in plant and soil. Therefore, two isolated PSB strains from maize rhizosphere were biochemically tested in vitro and identified by 16S rDNA gene analysis. The experiment was conducted in the greenhouse where the plant growth and nutrient availability to the plants were observed. In this regard, all the treatments such as PSB strain-inoculated plants, biochar-treated plants, and a combination of PSBs + biochartreated plants were destructively sampled on day 45 (D 45) and day 65 (D 65) of sowing with four replications at each time. PSB inoculation, biochar incorporation, and their combinations have positive effects on maize plant height and nutrient concentration on D 45 and D 65. In particular, plants treated with sawdust biochar + Lysinibacillus fusiformis strain 31MZR inoculation increased N (32.8%), P (72.5%), and K (42.1%) against control on D 65. Besides that, only L. fusiformis strain 31MZR inoculation enhanced N (23.1%) and P (61.5%) than control which shows the significant interaction of PSB and biochar in nutrient uptake. PSB and biochar have the potential to be used as a promising amendment in improving plant growth and nutrient absorption besides the conventional approaches.

“…The 12 isolates identified by PCR analysis produced IAA at concentrations between 0.11 and 0.52 µg mL -1 . This range is below that observed by Posada et al(2016) who reported concentrations produced by bacteria from the rhizosphere of banana between 1.9 and 60.0 µg mL -1…”

Screening of beneficial bacteria associated with Calophyllum brasiliense Cambess so as to develop microbial inoculants for agriculture

Beneficial bacteria belong to a group of microorganisms that are able to enhance plant growth by several mechanisms. In this study, phosphorus and zinc solubilizing, nitrogen-fixing and indole acetic acid (IAA) producing bacteria associated with C. brasiliensis were screened to develop microbial inoculants (MI) for use in agriculture. Characterization and identification of screened bacteria were also performed. A total of thirty-one nitrogen-fixing bacteria isolates were obtained, of which 28 showed the ability to solubilize phosphorus and 25 to solubilize zinc. The isolate AP-JNFb-3-2, belonging to the genus Pseudomonas, presented the highest value of solubilized phosphorus (100.4 µg mL-1). The isolates AP-JNFb-3-2 and RHI-JMVL-3-1, associated with the genera Pseudomonas and Enterobacter, respectively, showed the highest values for zinc solubilization (147.8 and 147.7 µg mL-1). Isolate RO-LGI.P-3-2, belonging to the genus Pseudomonas, was the most promising for IAA production (0.52 µg mL-1). The results obtained showed the presence of a large diversity of beneficial bacteria associated with C. brasiliensis, which may be explored as MI in agriculture.

“…Species that belong to the genus Bacillus can form endospores, which ensures the feasibility of commercial products with low storage requirements but a long shelf life (Posada et al, 2016). Thus, Bacillus strains can colonize the surface or wounds of postharvest fruit and produce broad-spectrum antibiotics that suppress a variety of plant pathogens (Stein, 2005).…”
