Serological and Pyocine Types ofPseudomonas aeruginosafrom Various Sources

Hospital Infection with Pseudomonas Pyocyanea: an Investigation by a Combined Pyocine and Serological Typing Method.

Serological Types of Clostridium perfringens.

In the flood of papers on the pathogenic anaerobes which appeared about 1920 several workers, particularly Zeissler (1919), Heller (1920), Hall (1922), came to the conclusion that agglutination reactions were of no value in the classification of the group. The apparent heterogenicity of strains of Clostridium perfringens has probably caused the greatest difficulty. Weinberg and Barotte (1928), ...

Pyocine Typing of Pseudomonas Aeruginosa.

The growth-inhibitory effect of a small group of different pyocines has been used to differentiate Ps. aeruginosa isolates. A method is described which can be carried out with ordinary media and is easy for routine application. One hundred and one isolates of Ps. aeruginosa were differentiated by four pyocines into 10 pyocine patterns.

Diversification of Nitrogen Sources in Various Tundra Vegetation Types in the High Arctic

Low nitrogen availability in the high Arctic represents a major constraint for plant growth, which limits the tundra capacity for carbon retention and determines tundra vegetation types. The limited terrestrial nitrogen (N) pool in the tundra is augmented significantly by nesting seabirds, such as the planktivorous Little Auk (Alle alle). Therefore, N delivered by these birds may significantly ...

Comparison of Various Sources of High Surface Area Carbon Prepared by Different Types of Activation

Activated carbon has been known as an excellent adsorbent and is widely used due to its large adsorption capacity. Activation condition and types of activation influence the surface area and porosity of the activated carbon produced. In this study, palm kernel shells and commercially activated carbon were used. To convert palm kernel shells into coal, two methods were employed, namely chemical ...
