The persistence and performance (growth promoting potential) of green fluorescent protein (gfp) marked Azotobacter chroococcum strain ABR 4G were studied in sterilized and unsterilized wheat rhizospheric soil. The gfp was integrated via Tn 5 transposition into A. chroococcum chromosome and the resultant gfp marked colonies were identified by green fluorescent emission under UV light. The gfp was stably maintained in A. chroococcum and the gfp insertion had no apparent adverse effect on the growth promoting properties of the marked soil isolate ABR 4G. The growth promoting properties (nitrogen fixation, ammonia excretion, phosphate solubilization and IAA production) of the parent soil isolate and the gfp marked strain were found to be almost the same. All the quantitative wheat plant traits were significantly influenced by inoculation of A. chroococcum ABR 4G strain in sterilized and unsterilized soil. Inoculated bacterial counts increased gradually in wheat rhizosphere, reached maximum on 60 th d and declined on 80 th d. Fertility levels also affected survival of marked strain and the survival was comparable in sterilized and unsterilized soil. The growth promoting properties were also determined from the marked strain reisolated from wheat rhizosphere in both types of soil. Fig 1, Tab 2, Ref

Ag-In intermetallic alloys were produced by using vacuum arc furnace. Differential Scanning Calorimetry(DSC) and Energy Dispersive X-Ray Spectrometry(EDX) were used to determine the thermal properties and chemical composition of the phases respectively. Microhardness values of Ag-In intermetallics were calculated with Vickers hardness measurement method. According to the experimental results, Ag-34 wt%In intermetallic system generated the best results of energy saving and storage compared to other intermetallic systems. Also from the microhardness results, it was observed that intermetallic alloys were harder than pure silver and Ag-26 wt%In system had the highest microhardness value with 143.45 kg/mm^(2).
