چکیده

The analytical electrophoretic pattern of the buffer-soluble proteins extracted from bacterial cells is both characteristic and descriptive of the organism (Hess et al., 1957; Wagman et al., 1958; Rodenberg, 1958). Further, a relatively large fraction of the material of the cell can be studied by the electrophoretic method. Hess et al. (1957) using successive extractive procedures on three strains of Streptococcus pyogenes obtained electrophoretic data on as much as 84 per cent of the dry weight of the cell and Rodenberg (1958) reported electrophoretic data on Proteus vulgaris strain OX-19 which were descriptive of 70 per cent of the total cellular nitrogen. It was the object of this study to determine whether altered environmental situations would produce sufficiently large qualitative or quantitative differences in the soluble proteins of the cell so that they might be detected electrophoretically. In part, some of these studies were reported previously (Rodenberg, 1957) and Wagman et al. (1958) found some corroborative results.

In vitro comparison of effects of extracts of Ailanthus altissima and Salvia nemorosa on Pseudomonas aeruginosa, Staphylococcus aureus and Proteus vulgaris

Introduction: Some plants have antiseptic roles and often do not cause harm to humans or animals. In this study, we try to introduce plants to disinfect spaces and surfaces contaminated with bacteria so that toxic substance does not remain in the environment. Materials and Methods: Ailanthus altissima and Salvia nemorosa extracts were used against lyophilized Pseudomonas aeruginosa, Staphyloco...

The Investigation of Anti-bacterial Activity of Holothuria Leucospilota Sea Cucumber Extracts (Body Wall, Guts and White Strings) at Chabahar Bay in Oman Sea

Echinoderms are independent and quite special branch of world animals. Sea cucumbers are among the strangest members of echinoderm class regarding their structure and physiology. These fauna have been tested with regard to anti-bacterial, anti-fungal, anti-coagulants, anti-virus, cytotoxic, hemolytic and anti-HIV features. In this study, the antibacterial activity of Holothuria leucospilota...

Preparation of Nanohydroxyapatite-Carbon Nanotube Composite Coatings on 316L Stainless Steel Using Electrophoretic Deposition

Nanohydroxyapatite-carbon nanotube composite coatings were deposited via electrophoretic deposition (EPD). AISI 316L stainless steel and ethanol were used as substrate and dispersing medium, respectively. 5%wt carbon nanotube (CNT) was used as reinforcing phase. Uniform and macrocrack-free coatings were obtained both for hydroxyapatite (HA) and HA-5%wt CNT coatings. Scanning electron micros...
