“…The various types of organic acid produced by KSMs were differing with different organisms. Organic acids were detected in the microbial suspension (Verma et al 2014;Zhang and Kong 2014;Maurya et al 2014). KSMs have the ability to weather phlogopite through acidic dissolution and aluminum chelation of the crystal network (Leyval and Berthelin 1989;Abou-elSeoud and Abdel-Mageed 2012;Meena et al 2014b).…”

Increasing cost of the fertilizers with lesser nutrient use efficiency necessitates alternate means to fertilizers. Soil is a storehouse of nutrients and energy for living organisms under the soil-plant-microorganism system. These rhizospheric microorganisms are crucial components of sustainable agricultural ecosystems. They are involved in sustaining soil as well as crop productivity under organic matter decomposition, nutrient transformations, and biological nutrient cycling. The rhizospheric microorganisms regulate the nutrient flow in the soil through assimilating nutrients, producing biomass, and converting organically bound forms of nutrients. Soil microorganisms play a significant role in a number of chemical transformations of soils and thus, influence the availability of macro-and micronutrients. Use of plant growth-promoting microorganisms (PGPMs) helps in increasing yields in addition to conventional plant protection. The most important PGPMs are Azospirillum,

“…Among these approaches, the use of plant growth-promoting (PGP) bacteria is believed as the most competent and economical system for escalating the yield of various crops (Ahemad and Kibret 2014). Various microorganisms such as the Bacillus, Pseudomonas and Trichoderma have been considered as potential plant growth-promoting factors and augment crop production under field conditions (Verma et al 2013). Various plant growthpromoting factors such as indole acetic acid (IAA), phosphate solubilization and nitrogen fixation, and bio-control attributes like production of HCN, siderophore, hydrolytic enzymes and antibiotics have been previously reported for Bacillus sp.…”

Background: Feathers are the major byproducts of poultry industry and considered as waste. Feathers (composed of protein keratin) are metabolized by a number of microorganisms as a source of carbon and nitrogen. Degradation of feathers results in production of amino acids and peptides, which can be employed as precursors for plant growthpromoting metabolites such as indole acetic acid, ammonia and HCN. The aim of the present investigation was to assess the influence of these metabolites (termed as feather protein hydrolysate) on plant growth promotion activity of keratinolytic bacterial strain Bacillus subtilis PF1.Results: Strain PF1 exhibits potent keratinolytic activity and can efficiently degrade 10 g/l chicken feathers under submerged cultivation with 81.4 ± 4.40 U/ml keratinase activity. Different concentrations of feathers supported the production of indole acetic acid by strain PF1. Strain PF1 produces maximum indole acetic acid (46.2 ± 0.21 µg/ml) in the presence of 2.0 % feathers at 120 h of incubation. The indole acetic acid production was confirmed by thin-layer chromatography and Fourier transform infrared spectroscopic analysis. However, increased concentration of feathers exhibited negative effect on phosphate solubilization due to increased alkalinity. HCN production also exhibited positive correlation with concentration of feathers. Finally, plant growth of Vigna radiata in the presence of strain PF1 with chicken feathers in soil was investigated, which showed good plant growth promotion activity. Increased ratio of C/N in soil also supported the plant growth promotion activity of feathers. Conclusion:Feather degradation property of B. subtilis PF1 could be efficiently utilized for feather waste management. The metabolites released by feather degradation along with strain PF1 could be successfully employed as an economic source of nitrogen fertilizers for plants.

“…Furthermore, they are an important component of integrated nutrient management and plant nutrition system (Raghuwanshi 2012). Possible mechanism of the effectiveness of biofertilizers include mobilization of sparingly available plant mineral nutrients nitrogen fixation and solubilisation of zinc (Goteti et al 2013), potassium (Maurya et al 2014) and phos-phorus (Verma et al 2014). O'Connell (1992) stated that the application of biofertilizers containing beneficial microorganisms instead of synthetic chemicals are known to improve plant growth through the supply of plant nutrients and may help to sustain environmental health and soil productivity.…”
