“…Further future studies are needed to answer such questions. This is an agreement with other the solubilization of P was due to the production of organic acids (Dastager et al, 2010;Pandey et al, 2006), siderophore (Sharma et al, 2013), indole acetic acids (Sergeeva et al, 2007), phytase (Acu?a and Jorquera, 2011;Konietzny and Greiner, 2004), and protons during ammonia respiration Ramesh et al, 2014;Reyes et al, 2006).…”

This study aimed to isolate and identify highly adapted and highly efficient phytate-mineralizing bacteria from calcareous soil located in northern area of Egypt of arid and semiarid climate conditions. Using direct pour plate method, NBRIP medium was supplemented with phytate (5.0 g/L).The isolate showed the largest halo zone was further studied for its effectiveness in mineralizing phytate. The newly isolated strain was identified through the sequencing and the analysis of its nearly full 16S rRNA gene and was identified as Klebsiella pneumonia strain MK1C with GenBank accession number KU358675 based on BLASTn database. On liquid NBRIP culture, Klebsiella pneumonia strain MK1C showed high growth that was associated with a significant reduction of its pH from 6.8 to 4.7 and up to 5 times higher production of organic acids compared to uninoculated treatments. As a result, more than 50% of the organic phosphorus of added phytate was released as inorganic phosphorus. This strain could be an excellent dual-biofertilizer for both phytate mineralization and dinitrogen fixation. This is especially important for soils with poor conditions such as calcareous soils or in areas of arid and semiarid climate conditions where this strain and its related species are highly adapted.

Bacterial fruit blotch (BFB), which is caused by Acidovorax citrulli, is a serious threat to watermelon growers around the world. The present study was conducted to screen effective rhizobacterial isolates against 35 different A. citrulli isolates and determine their efficacy on BFB and growth parameters of watermelon. Two rhizobacterial isolates viz. Paenibacillus polymyxa (SN-22), Sinomonas atrocyanea (NSB-27) showed high inhibitory activity in the preliminary screening and were further evaluated for their effect on BFB and growth parameters of three different watermelon varieties under greenhouse conditions. The greenhouse experiment result revealed that SN-22 and NSB-27 significantly reduced BFB and had significant stimulatory effect on total chlorophyll content, plant height, total fresh weight and total dry weight compared to uninoculated plants across the tested three watermelon varieties. Analysis of the 16S ribosomal RNA (rRNA) sequences revealed that strains SN-22 belong to P. polymyxa and NSB-27 to S. atrocyanea with the bootstrap value of 99% and 98%, respectively. The isolates SN-22 and NSB-27 were tested for antagonistic and PGP traits. The result showed that the tested isolates produced siderophore, hydrolytic enzymes (protease and cellulose), chitinase, starch hydrolytic enzymes and they showed phosphate as well as zinc solubilizing capacity. This is the first report of P. polymyxa (SN-22) and S. atrocyanea (NSB-27) as biocontrol-plant growth promoting rhizobacteria on watermelon.

“…B. aryabhattai inoculated treatment recorded highest major and minor nutrient concentration, especially Zn concentration in tomato fruit (31.1ppm). Similarly inoculation of B. aryabhattai to soyabean and wheat crop significantly increased the zinc concentration in soyabean seed and wheat grain between 49.70 and 61.25 mg/kg (Ramesh et al, 2014). Mader et al, (2011) also reported a substantial increase in Mn and Zn concentration in rice grains due to application of combination of natural mycorrhiza consortia and fluorescent Pseudomonas strain R62 + R81.…”
