“…Increased root length and numbers of root hairs also increase the surface area of root which enhances the absorption of nutrients from soil. This result is comparable with that of Paul et al (2013) who reported the role of feather hydrolysate in enhancing the number of root hairs. Increased weight of shoot and plumule length revealed the promotion of plant growth.…”

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.

“…Feathers consist of 90% keratin and constitute 5-7% of the total weight of adult chickens (Suntornsuk and Suntornsuk 2003, Costa et al 2012, Paul et al 2013. Feathers are discarded in the process of poultry processing and as a waste product contributes to environmental pollution (Grazziotin et al 2006, Vasileva-Tonkova et al 2009, Staroń et al 2013.…”

Recently, the increased consumption of poultry meat in the EU has been observed. Short cycle of poultry meat production allows adjusting the level of production to demand. With the increase in the meat production the amount of generated waste that has to be disposed because they pose a risk to the environment also increases. The work presents the possibility to produce a mixture of feathers, meat-bone meal and poultry litter that can be used for energy purposes (alternative fuel). Moreover, the composition of the ashes after combustion will be similar to phosphorus-potassium fertilizers offered for sale. The resulting granules are characterized by a calorific value in the range 13.1-13.3 kJg -1. The ash after its combustion contained 11.33-13.38% of phosphorous, 4.94-5.67% of potassium, 31.85-32.69% of calcium and 2.07-2.51% of magnesium. Moreover, the ash contained 0.45-0.46% of iron, 0.10-0.11% of manganese, 0.11-0.14 of zinc and 0.02% of copper. Mineral combusted residue of this type of granules has a low content of heavy metals and can be used as an additive to fertilizers and soil improvers, in order to enrich their composition in valuable macro-and micronutrients.

“…Biological treatment of feather was found to be the most suitable alternative not only because it allows the removal of feather which is intensively attained from poultry industry in a clean way but it also produces the high nutritional value feather meal which might be introduced again to animal feed (Saha et al, 2013) or used as organic fertilizer (Paul et al, 2013). This process can be performed by fungi (e.g.…”

Feather which mainly contains Keratin is one of the main poultry industry wastes and at the same time with high nutritional value if converted to soluble form. In this study, we isolated and characterized four alkaliphilic bacteria for their ability to degrade feather under alkaline conditions. Two of the isolates have been identified as Lysinibacillus spp. and both of them are growing optimally at 30 °C and pH 9. The others were identified as Micrococcus sp. and Nocardiopsis sp. and both of them showed optimum growth at 37 °C and pH 10.5. All the isolates are promising and potential tools that could be used for keratin degradation.
