“…The phosphate-solubilizing bacteria (PSB) can convert the insoluble inorganic phosphate compounds, such as tri-calcium phosphate, di-calcium phosphate, hydroxyapatite, and rock phosphate, to plant available forms. Many bacterial genera were reported to have Psolubilization activity such as Pseudomonas, Bacillus, Rhizobium, Burkholderia, Erwinia and Klebsiella (Rodríguez and Fraga, 1999;Yao et al, 2006 andWalpola et al, 2014).…”

Nitrogen (N), Phosphorus (P) and Potassium (K) are the major essential macro-nutrients for plants. The ability of soil bacteria to provide available forms of these nutrients to plants is an important feature in the bacterial strain used as a biofertilizer. In this study, fifteen isolates of Azotobacter spp were isolated. The efficiency levels of the N 2 -fixation were tested, the isolates reduced acetylene at rates of 6.348 -1381.023 nmoles C 2 H 4 /ml/day. The most active isolate was No. AZ 8 that identified as Azotobacter chroococcum MF135558. Twenty-one phosphate-solubilizing bacteria (PSB) were isolated and solubilization efficiency % (SE%) of each isolate was determined by spot inoculation technique. Five isolates (PSB 3, PSB 7, PSB 8, PSB 12 and PSB 14) were chosen due to their high solubilization efficiency % (SE%) 182. 35, 173.33, 222.22, 170.00 and 194.11 %, respectively. The five P-solubilizing bacteria were tested for their ability to solubilize P from tri-calcium phosphate and rock phosphate in liquid Pikovskaya's medium. The highest quantity of released phosphorus in actively growing culture was 36.52 mg/100 ml after 28 days of incubation and 1.095 mg/100 ml after 3 days of incubation on tri-calcium phosphate and rock phosphate, respectively by isolate PSB 14 which was identified as Klebsiella oxytoca MF135559. Five isolates of K-releasing bacteria (KRB) were isolated on Alexandroov's medium and were tested to release K from mica-muscovite. All the tested isolates can release potassium from mica but not in equal efficiency. The most efficient isolate namely KRB-2 could release 7.05 ppm after 6 weeks of incubation. It was identified as Rhizobium pusense MF135560.

“…Rhizospheric microorganisms mainly the genus Bacillus, have large potential in the biological control of phytopathogenic nematodes as well as growth promoters (Fernandes et al, 2013). According to Yao et al (2006), B. subtilis has been used commercially for biocontrol of plant diseases, as well as to increase crop productivity. These effects may have been reflected in the initial and final stand, where the treatment with B. subtilis inoculation presented higher values than the control in both experiments (Tables 3 and 5).…”

The objective of this study was to evaluate the efficiency of Bacillus subtilis inoculation in the agronomic performance of the soybean cv. M 9144 RR crop under field conditions. Two field experiments were developed with inoculation by B. subtilis in soybeans in two regions. The experiments were conducted in 2015/2016 harvest from December to April. The experiment was performed in a randomized block design with four replicates with and without inoculation by B. subtilis. Consequently, biomass and productivity were determined. The B. subtilis inoculation increased soybean biomass in both assessment regions. This bacterium showed increased soybean yield in Gurupi and Araguaçu soils (Tocantins, Brazil), with increases above 14.9 and 8.8%, respectively. The inoculation of the strain B. subtilis UFT-Bs10 provided biomass increase, nodulation, stand maintenance and increased yield of soybean cv. M 9144 RR in field conditions.

Nitrogen and phosphorous are critical determinants for plant growth and productivity. Some soil bacteria can provide them in available forms to plants. These bacteria can be used as nitrogen fixers biofertilizers. In the current study, eighteen isolates of Azotobacter spp. were separated. The efficacy concentrations of the N 2-fixation were examined using acetylene reduction technique, the isolates reduced acetylene at rates of 31.01 to 861.01 nmoles C 2 H 4 /ml/day. The highest lively isolate was No. AZ 14; recognized as Azotobacter beijerinckii. 8 phosphate-solubilizing bacteria (PSB) were insulated. These 8 Psolubilizing bacteria were analyzed for the tendency to solubilize P from tri-calcium phosphate in liquid Pikovskaya's medium. The uppermost amount of free phosphorus in vigorously developing culture was 0.3652g g/100 ml after 28 days of cultivation and 0.1515g/100 ml after 7 days of cultivation on tri-calcium phosphate, correspondingly by isolate PSB 5 which was recognized as Bacillus paramycoides. Both nitrogen fixing bacteria and P-solubilizing bacteria isolates were genetically identified according to www. ncbi.nlm.nih.gov/blast data bank. The two isolates were defined according to standard morphological and biochemical tests as well as molecular tests.
