“…Increase in IAA concentration occurs till 72 h and thereafter decrease was notice after 96 h of incubation. The range of IAA production was 10-26 lg/ml after 72 h of incubation (Patel et al 2011). Most studies have shown that IAA biosynthesis is greatly influenced by L-TRP precursor.…”

A novel Enterobacter cancerogenus MSA2 is a plant growth promoting gamma-proteobacterium that was isolated from the rhizosphere of Jatropha cucas a potentially important biofuel feed stock plant. Based on phenotypic, physiological, biochemical and phylogenetic studies, strain MSA2 could be classified as a member of E. cancerogenus. However, comparisons of characteristics with other known species of the genus Enterobacter suggested that strain MSA2 could be a novel PGPB strain. In vitro studies were carried for the plant growth promoting attribute of this culture. It tested positive for ACC (1-aminocyclopropane-1-carboxylic acid) deaminase production, phytase, phosphate solubilization, IAA (Indole acetic acid) production, siderophore, and ammonia production. The isolate was then used as a inoculant for the vegetative study of Jatropha curcas plant. Enterobacter cancerogenus MSA2 supplemented with 1% carboxymethylcellulose showed overall plant growth promotion effect resulting in enhanced root length (124.14%), fresh root mass (81%), fresh shoot mass (120.02%), dry root mass (124%), dry shoot mass (105.54%), number of leaf (30.72%), chlorophyll content (50.41%), and biomass (87.20%) over control under the days of experimental observation. This study was designed for 120 days and was in triplicate and the data was collected at every 30 days.

“…Paenibacillus polymyxa (formerly Bacillus polymyxa) is most widely studied strain from this genus; it has ability to fix nitrogen and capable of producing antibiotic named polymyxin, and it is widely used as biocontrol agent for control of phytopathogens in agriculture (Eastman, Weselowski, Nathoo, & Yuan, 2014). Microbes are considered as a major resource for agricultural applications (Patel, Jha, Tank, & Saraf, 2011); however, strains other than P. polymyxa belonging to this genus are poorly studied for their role in agriculture.…”

Bacterium Paenibacillus mucilaginosus strain N3 was isolated from agricultural farm soil (located at Boriavi village, Gujarat, India). Isolate showed an evidence of non-symbiotic nitrogen fixation, when grown in nitrogen-free bromothymol blue growth medium. It was tested positive for direct plant-growth-promoting traits like Indole-3-acetic acid production, solubilization of Tri-calcium-phosphate, and ammonia production. Further, N3 isolate was tested positive for siderophore production of catecholate type and catalase production as an indirect plant-growth-promoting trait. Biochemical tests along with 16s rRNA gene sequence analysis confirmed the strain N3 to be P. mucilaginosus. To determine its efficacy as a plant-growth-promoting rhizobacteria (PGPR), its talc-based biofertilizer was prepared and tested on the growth of green gram (Vigna radiata). Seeds treated with this biofertilizer showed an increase in overall dry biomass by 17% and sapling length by 28% (as compared to non-treated controls) after 10 days of sowing in pots. Thus, multiple plant-growth-promoting traits of P. mucilaginosus N3 determined in vitro along with its ability to promote growth in green gram in vivo we characterize this strain as an efficient PGPR.

“…We found several siderophore producing strains belonging to pseudomonads and bacilli. IAA production by PGPR strains in significant amount has also been reported Patel et al 2011). Mycolytic enzymes, such as chitinase, β-1,3-glucanase, protease, etc., are being exploited widely for crop disease management practices.…”

“…Similarly, Pandya & Saraf (2010) reported that application of bioinoculants to chickpea having potential of phosphate solubilization and siderophore production increases in all the vegetative growth parameters under saline conditions. Patel et al (2011) also reported that strains MSC1 (Pseudomonas putida) and MSC4 (Pseudomonas pseudoalcaligens) showed increases in all vegetative parameters of chickpea under saline conditions. Similarly, enhancement of growth parameters of groundnut by pseudomomads has also been reported by a number of authors (e.g., Gupta et al 2002;Kishore et al 2005;Bhatia et al 2008).…”

Present study was designed to determine the microbial diversity from three distinctive sites (amended with vermicompost) of Gujarat, India. A set of 76 strains were screened from total of 438 strains that exhibit plant growthpromoting (PGP) and antagonistic potential isolated from sites PS1 (Mehsana district), BS2 (Dantiwada district) and VS3 (Gandhinagar district). Their diversity indices were studied for determining the species richness and evenness of screened isolates. Results revealed that site BS2 showed the most significant diversity indices in terms of Shannon (H 1.525) and Simpson (1/D 5.120) than other two samples. Principal component analysis showed that bacterial diversity (H ) was correlated with the soil characteristics. Chickpea and groundnut plants inoculated with MBCU1 and MBCU3 isolates showed an increase in the vegetative growth parameters that evaluate plant growth when compared to uninoculated controls. Strains MBCU1 and MBCU3 were identified as Pseudomonas stutzeri and Pseudomonas mosselii, respectively, according to sequence analysis of the 16S rRNA gene. These both isolates belong to site BS2 and they showed specific PGP traits suggesting that these isolates can promote plant growth by more than one mechanism with respect to their higher diversity index.
