Production of biofertilizers using baker's yeast effluent and their application to wheat and barley grown in north Sinai deserts

Increase in Growth, Productivity and Nutritional Status of Wheat (Triticum aestivumL.) and enrichment in Soil Microbial Population Applied with Biofertilizers Entrapped with Organic Matrix

“…The higher productivity in wheat crop was also reflected by increased total soluble protein, total organic nitrogen and free ammonium with the application of SGBF at 45 and 60 days after sowing (Figure 1). The customized fertilizers have been reported to improve the productivity in wheat (Mubeen, 2004, Mubeen et al, 2006Ali et al, 2005;Carlier et al, 2008;Shaharoona et al, 2008). Nutritional status of wheat grain which include protein, moisture, starch, wet gluten, zeleny and nutrients uptake of N, P, and K kg ha −1 in grain and straw does not differ significantly with application of SGBF, CB, and CU over NF (Tables 3 and 4).…”

“…Azotobacter chroococcum and Bacillus subtilis are commonly supplied as charcoalbased inoculants and has been applied for wheat cultivation (Mahajan et al, 2003;Ogut et al, 2005;Broschat and Moore, 2007;Kumar et al, 2010;Ramanjaneyulu et al, 2010) Though biofertilizers offer an economically attractive and ecologically sound alternative to CU, its efficacy is significantly low in relation to the crop yield than that for the chemical fertilizer. Some studies have been conducted with the application of CRFs, SRFs, and CFs for cultivation of different crops including wheat (Dahiya et al, 2004;Mubeen 2004;Ali et al, 2005;Mubeen et al, 2006;Carlier et al, 2008;Shaharoona et al, 2008;Kandil et al, 2010;Sharma and Singh, 2011;Kumar et al, 2012). Studies have demonstrated that CU entrapped in the organic-matrixbased super granules are more effective in rice, Indian mustard and other crops (Dahiya et al, 2004;Sharma and Singh, 2011;Kumar et al, 2012).…”

The influence of agro-industrial effluents on River Nile pollution

“…Therefore, the potential polluting stress of such agro-industries has intrigued researchers both at home and abroad. In previous publications [12,13], we clearly demonstrated the potential polluting capacity of baker's yeast effluent, and the very efficient aerobic biotreatment, prior to disposal, through biomass production of diazotrophic bacteria. Table 2 presents their rich load of organic carbon (26-62%), nitrogen (0.4-1.7%), cations (32-1970 ppm), anions (269-5338 ppm), and micro-elements (0.9-23.7 ppm).…”

“…Statistically, Klebsiella pneumoniae and Chryseomonas luteola in particular positively responded with successive amendments of starch effluent. Active cell growth of tested diazotrophs nominates such effluents for the production of value-added microbial biomass necessary to formulate bio-preparates, biofertilizers and biocontrol agents [12,13].…”

“…fluorescens for pulp and paper mills' effluents [11]. Ali et al [12,13] demonstrated the successful biodegradation Periodic water samples were manually and aseptically collected from the surface water, (ca. <1 m ashore), in sterile brown bottles (200 ml capacity).…”
