Bu çalışmada, Mardin İlinde bir kamu kurumuna ait iki su kuyusu, deposu ve binaların musluklarından alınan sürüntü numunelerinde mikrobiyolojik kimyasal analiz yapılmıştır. Legionella serogruplarının varlığı ile klor, nitrat, nitrit, pH elektriksel iletkenlik gibi parametreler edilmiştir. Alınan 25 örneğinden üremesi gözlenmezken. aynı yerlerden kültür örneğinin 4 tanesinde L. pneumophila serog...

The combined effect of superficial gas velocity, pH, initial phosphate concentration, and light intensity on cell growth was investigated for the mass production of cyanobacterial cells. The light intensity was manipulated to maintain a specific irradiation rate (q(i)) at a constant level for high cell density culture. The optimum condition for the batch culture was achieved at a superficial ga...

as 'goat lactoglobulin' gave a single peak on electrophoresis at pH 8.0 in barbiturate buffer, but three boundaries separated at pH 7-0 and at least two at pH 4-2-6-0 after 2 hr. at 4-5 v/cm., I= 01. The two main components had their isoelectric points at pH 5-2 and 5-9 respectively in sodium acetate buffer, I= 0-1. 'Goat lactoglobulin' thus behaved in much the same way as crystalline bovine ,B...

Increasing urbanisation and industrialisation have led to a dramatic reduction in forest area, and now only culturally protected remnants of natural forests and some new plantations remain in most areas of the north of Iran. To investigate the status of the chemical and physical characteristics of soil under these remnant forests and assess the possible impacts of reforestation on soil properti...

phenol and its homologues are aromatics containing hydroxyl, methyl, amide and sulphonic groups attached to the benzene ring. these molecules are both anthropogenic and xenobiotics. phenols are environmental pollutants discharged through wastewaters from various industries. phenols are toxic to several biochemical reactions. however biological transformation of phenols to non-toxic entities exi...

abstract considering to importance and high genetic diversity of pear (pyrus communis l.) in iran, a study was conducted on the effect of genotype on fruit physicochemical properties and qualitative characteristics of six mature european pear genotypes in teheran, iran environmental conditions. in this study some physicochemical fruit properties and qualitative characteristics such as: fruit le...

In order to optimize the micropropagation of Qare-Qat (Vaccinium arctostaphylus J.J.Sm), samples were collected from two regions of Iran (Asalem and Kelardasht). Anderson (AN) media containing different concentrations of zeatin (0, 0.5, 1, 2 and 4 mg L-1) and different levels of pH (4.5, 5 and 5.5) were compared. The in vitro shoots were transferred on AN media supplemented with zeatin (1 and 2...

The in vitro activities of mupirocin, quinupristin/dalfopristin, linezolid, eperezolid, sitafloxacin, clinafloxacin, moxifloxacin, amoxycillin, metronidazole and clarithromycin were tested at pH 7.4 against 57 strains of Helicobacter pylori. The most active agents (mupirocin, sitafloxacin and clinafloxacin) were also tested for activity at pH 5.4 against the same strains. Mupirocin was very act...
