A field study was performed to determine the efficiency of diammonium phosphate (DAP) applied alone or combined with biochar, lignite, and farmyard manure (FYM) on growth and cadmium (Cd) accumulation in wheat and rice. Before crop sowing, different treatments were applied in the field such as a control (T-1), DAP alone (0.1%, T-2), DAP + lignite (0.05% each, T-3), DAP + FYM (0.05% each, T-4), and DAP + biochar (0.05% each, T-5). Afterwards, the wheat seeds were sown in the soil. At wheat postharvest, rice was sown without any further treatment. Raw effluent was applied as an irrigation source during the whole growth period of both crops since it is the common practice of the farmers of study area. It was revealed that the use of amendments enhanced the yield and photosynthesis but lowered the Cd contents in straw as well as grains of both crops. In both crops, the highest yield of straw and grain was found in DAP + FYM whereas the lowest Cd concentration was found in DAP alone. The ammonium bicarbonate-DTPA extractable Cd of post wheat and post rice soils were decreased while the soil pH and immobilization index were increased in all treatments as compared with the control. The present field study highlighted that the DAP + FYM can be effective in increasing yield with decreased Cd concentrations in crop grains.

The performance of both free and solid supported urease for the enzymatic hydrolysis of urea was studied. Kinetic analysis of reaction rate data shows that the kinetic data were consistent with the proposed model. Statistical tests validated the model. Despite the deactivation of ureases, the immobilized enzyme could be the choice for a technological process aiming at the detoxification of blood in haemoperfusion columns.
A study of the relative dominance of selected anaerobic sulfate-reducing bacteria in a continuous bioreactor by fluorescence in situ hybridization
İçgen, Bülent; Harrıson, S.T.L. (Springer Science and Business Media LLC, 2007-01-01)
The diversity and the community structure of sulfate-reducing bacteria (SRB) in an anaerobic continuous bioreactor used for treatment of a sulfate-containing wastewater were investigated by fluorescence in situ hybridization. Hybridization to the 16S rRNA probe EUB338 for the domain Bacteria was performed, followed by a nonsense probe NON338 as a control for nonspecific staining. Sulfate-reducing consortia were identified by using five nominally genus-specific probes (SRB129 for Desulfobacter, SRB221 for De...
A Combined Method of Protein Extraction from Unorthodox Plant Samples for Proteomics
Yılmaz, Can; İŞCAN, MESUDE (2021-01-01)
Aim: This study aimed to generate an improved method of protein extraction and purifi-cation from plant tissues containing very high amounts of phenolic compounds and other interfer-ing biomolecules. Background: Protein extraction at proteomic studies on some plant species, including conifers, is challenging, and the yield and quality are unpredictable. Objective: Two popular protocols were combined with each other to construct a novel one with en-hanced abilities to produce higher purity of samples compati...
The production of citric acid by using immobilized Aspergillus niger A-9 and investigation of its various effects
Demirel, G; Yaykasli, KO; Yasar, A (2005-02-01)
The production of citric acid was achieved by using Aspergillus niger conidiaspores, entrapped in Ca-alginate beads, and the factors that affect this production were investigated. The effects of starting sucrose concentration (100-180 g/l), nitrogen concentration (0-0.3 g/l), methanol concentration (0-6 ml) and finally ethanol concentration (0-5 ml) in 100 ml feeding medium on citric acid production were studied and optimum experimental conditions were determined. The starting nitrogen concentration (0.05 g...
Investigation and development of possible leaching processes for recovery of zinc and lead from çinkur leach residues
Sunkar, Ahmet Semih; Topkaya, Yavuz Ali; Department of Metallurgical and Materials Engineering (2005)
The major aim of this study was to investigate various leaching methods for the recovery of zinc and lead from blended neutral leach residues of Çinkur having a composition of 12.59 % Zn, 15.21 % Pb, 6.45 % Fe, 0.054 % Cd. Initially water leaching tests were performed at various conditions of leaching temperature, reaction time and particle size. The optimized conditions for water leaching were found to be 2 h, 95?C and 250 g/l pulp density with a final pH of 5.9. However, the zinc recovery value of 10.26 %...
