“…Significantly highest ascorbic acid content of plant was found in Pseudomonas striata X ZnSO 4 30 kg ha -1 (37.76 mg 100 gm -1 -30 DAS and 42.00 mg 100 gm -1 -45 DAS). However the lower values of ascorbic acid content of plant was recorded in control plots.Experimental result are in agreement with the reports ofVidyashree et al (2018)…”

Field experiment was conducted during kharif season of 2018 at Research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to assess the response of spinach crop to various zinc solubilizers and graded levels of zinc on quality parameter and chemical properties of soil. Experiment consists of sixteen treatments in which four zinc solubilizers (Pseudomonas striata, Bacillus megaterium, Trichoderma viride and Control) and four graded levels of ZnSO4 (0 kg ZnSO4 ha -1 , 10 kg ZnSO4 ha -1 , 20 kg ZnSO4 ha -1 and 30 kg ZnSO4 ha -1 ) were used in factorial randomized block design. Seed treatment of spinach was done with zinc solubilizing microbial cultures and application of zinc in graded doses at the time of sowing with recommended dose of fertilizers. The quality attributes improved significantly with inoculation of Psuedomonas striata + 30 kg ZnSO4 ha -1 . The pH, EC, organic carbon and calcium carbonate after harvest of spinach indicates nonsignificant interactive results.

Zinc is one of the micronutrients, required by all types of crops. About 10–100ppm of zinc is present in soil which is generally immobile. The cow dung sustains all life and being practice since aeons. Exploitation of cow dung bacteria can mobilize nutrients besides contributing in sustainable agriculture. Therefore, to examine mobilization of Zn, cow dung is used as a source of bacteria. The objectives of the present study were to isolate an array of bacteria from cow dung and to characterize them for their Zn (ZnO and ZnCO3) mobilization ability in addition to establish the optimum conditions for dissolution of zinc. A total of seventy bacterial isolates have been screened for Zn mobilization. Out of which most potent (CDK15 and CDK25) were selected to study the effect of various parameters viz. pH, temperature and concentration of Zn. These parameters were assessed qualitatively in diverse growth medium and quantitatively using Atomic absorption spectroscopy. Optimum pH and temperature for mobilization was recorded at pH 5 (ZnO) and 37 °C (ZnCO3) by CDK25, whereas, optimum zinc concentration for mobilization was recorded at 0.05% (ZnO) by CDK15. Maximum amount of Zn solubilized was recorded by CDK25 in ZnO (20ppm). Considering the abilities of most potent bacterial isolates with reference to P-mobilization and growth promoting traits, pot culture assay of C. annuum L. was carried out. The findings of which conclude that, bacterium CDK25 (Bacillus megaterium) could be exploited for factors viz. nutrient management of Zn, growth promoting agent, and Zn augmentation in soil.

“…Autotrophic bacteria, e.g., sulfur/iron (III) and iron (Fe)-oxidizing bacteria, have been investigated for metal solubilization and thereby used for the recovery of metals (Zn, Ni, and Cu) from industrial waste and ores (Schippers et al, 2014;Costerousse et al, 2017). For the past decade, heterotrophic bacteria that solubilize Zn and promote plant growth have been studied for improved plant productivity and significant Zn accumulation in the edible parts of plants after their inoculation (Costerousse et al, 2017;Gontia-Mishra et al, 2017;Kamran et al, 2017;Mumtaz et al, 2017;Idayu Othman et al, 2017;Saravanan et al, 2007;Ramesh et al, 2014;Vaid et al, 2014;Upadhayay et al, 2022b;Vidyashree et al, 2018).…”

Contemplating the role of zinc-solubilizing bacteria in crop biofortification: An approach for sustainable bioeconomy

Modern agriculture pays attention to improving agricultural production by producing zinc-enriched crops through zinc-solubilizing bacteria to strengthen the bioeconomy. Zinc deficiency in the soil reduces plant growth and also leads to less uptake of zinc in the edible portion of plants. Therefore, the zinc content in the edible parts of plants can be increased through the biofortification approach. However, most of the biofortification approaches are laborious and need expensive input in routine practices. Therefore, the microbiological biofortification approach may be beneficial in increasing the zinc concentration in plants and improving crop quality with the ultimate benefit of a greener path. The use of microbes may thus be favorable for elevating zinc content in plants and enhancing crop quality, ultimately providing a summation of the role of microorganisms for a greener strategy. In addition, the application of zinc-solubilizing bacteria as a potential biosource represents a cost-effective and alternate biofortification strategy. Zinc-solubilizing bacteria act as natural bio-fortifiers that can solubilize the unavailable form of zinc by secreting organic acids, siderophores, and other chelating compounds. This review thus focuses on zinc-solubilizing bacteria for plant biofortification and their contribution to enhance crop yield and the bioeconomy in a more sustainable manner.
