“…Other procedures utilized for ashing biological material include dry ashing at 400-500°C (Baker et al, 1964), low-temperature ashing in a plasma furnace (Riley and Roth, 1971) and acid digestion (Thiers, 1957;Gorsuch, 1970;Abu-Samra et al, 1975).…”

A series of procedures including cultivation, harvesting, washing, drying, ashing, and chemical preparation were developed for the analysis of the elemental composition of Pseudomonas putida cells. The composition of P. putida grown in continuous culture in five separate experiments at 30°C, pH 7.5, in 0.1% peptone-yeast extract medium adjusted to a salinity of 26.5 g/L was averaged in µg/g for 50 subsamThe critical steps in the procedure were washing three times with "pure" 4°C water using mechanical agitation and homogenization of the dried cells with an agate mortar and pestle.Address reprint requests to G.

Alfalfa (Medicago sativa L.) clones tolerant to salt stress: in vitro selection

et al. 2013

In order to quickly and efficiently evaluate the salt tolerance of alfalfa, salinity tests were conducted on Medicago sativa L. var. australis, var. icon, var. loi, and var. gea, under in vitro conditions. Pregerminated seeds of four varieties were subjected to five different NaCl concentrations (0, 50, 100, 150, 200 mM). The influence of saline stress was estimated on the basis of survival percentage, growth parameters, and electrolyte leakage. The seedlings surviving on the medium enriched with salt at the highest concentration were presumed to be tolerant and represented the mother plants for the production of in vitro clones. In the following step, the clones were evaluated in vitro to confirm the salt tolerance. The influence of mild salt stress (75 mM NaCl) on the growth parameters of selected clones was examined. At the end of this trial, the proline accumulation and sodium content in alfalfa shoots were also quantified. The results suggest an increased level of proline promotes salt tolerance. Medicago sativa L. var. icon is highly tolerant in comparison with the other varieties tested. In vitro selection of M. sativa L. varieties on salt-containing media allowed us to obtain clones with increased salinity tolerance.

“…The total nitrogen (Bremner, 1996), total P, total K and CEC (ammonium acetate, pH 7, leaching method) of biochar samples were determined using autoanalyzer (QuickChem FIA 8000 Series, Milwaukee, Wisconsin). The concentrations of Ca and Mg of biochar were determined by using the dry ashing method (Baker et al, 1964) with atomic absorption spectrophotometer AAnalyst 400 (Perkin Elmer, Norwalk, CT, USA). Total As and Cd content in biochar was determined using atomic absorption spectrophotometer after digestion with aqua-regia (1:3 HCl to HNO 3 ) solution.…”

Biochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit Bunch (EFB) and Rice Husk (RH) as heavy metals adsorbents. The morphology of EFB biochar comprise rigid structure with uniform pores size. The surface area of biochars ranged between 23.22-46.32 m 2 g −1 , dominated with mesopores. The chemical characterization of biochars revealed high carbon content in EFB biochar compared to RH biochar (54.08 and 7.78%). Both biochars are alkaline in nature (>pH 9) and contain substantial amounts of N, P, K, Ca and Mg. Fourier transform infra-red spectra showed the heterogenic functional groups on EFB biochar surface and domination of silica content in RH biochar. The batch experiment was employed to determine the adsorption capacity of these biochars for As and Cd. The adsorption data were fitted well in Langmuir isotherm with high correlation coefficient (R 2 >0.9) for As and Cd. The q max of EFB biochar for As and Cd was higher than RH biochar. The q max of EFB biochar was 0.4240 and 15.1515 mg g −1 for As and Cd, respectively. In contrast, the q max of RH biochar for As and Cd was only 0.3522 and 3.1908 mg g −1 . The results show that EFB biochar and RH biochar have potentials as good sorbent for As and Cd. Therefore, it can be suggested that the application of these biochars may possibly reduce the trace elements availability in the contaminated soil.
