Abstract
Ability of Al- acclimatized Immobilized Nostoc muscorum to Combat Abiotic Stress and its Potential as a Biofertilizer
Highlights
Bio-fertilizers are eco-friendly and have been proved to be effective and economical substitute of chemical fertilizers with smaller input of capital and energy (Bhardwaj et al 2014)
Control acclimatized immobilized as compared to free living N. muscorum. These results reasonably indicate the ameliorative role of Al- acclimatization and immobilization on N. muscorum and the same could be attributed to Al induced dehydration stress which in turn might have accelerated proline production Sharma and Dubey 2005
This finding is in consonance with the reports of Hussaini et al, 1996 which showed that low concentration of Al in the form of AlCl3 were noninhibitory to N.linckia at pH 7.5 and establishes the fact that low concentrations can sometimes increase plant growth or induce other desirable effects as was suggested by Foy, 1983
Summary
Bio-fertilizers are eco-friendly and have been proved to be effective and economical substitute of chemical fertilizers with smaller input of capital and energy (Bhardwaj et al 2014). Immobilization process unlocks the possibility of appropriate storage and transportation of required cyanobacterial strains for using them as inoculum in crop field and in poor quality soil to escalate the fixed nitrogen content. For to Al stress and to other abiotic the acclimatization of the N. muscorum, cells were stresses mediated by over expression of proline initially subjected to very low dose (0.1 μM) of Al and subsequent immobilization of Al acclimatized and subsequently transferred every 15 days to the cells will enhance their efficacy as biofertilizer as higher concentrations (1, 10, 20, 30, 40 and 60 a result of enhanced activity of nitrogen fixing μM) with regular growth study at each step of cells apparatus. Lowry et al.1951 at each successive treatment with higher dose of Al to see the proper growth of N
