Serological relationships between shigella and coliform cultures.
Definitive studies of the serological relationships between members of the E&chericki coli group and other groups within the family Enterobacteriaceae were made possible by the differentiation of the thermolabile and thermostable somatic antigens of E. coli cultures (Kuffmann, 1943, 1944a) and the subsequent introduction and establishment of the Kauiffmann-KnipschildVahlne antigenic schema. As ...
متن کاملAeration Stress in Plant Tissue Cultures
The requirement for sterility in plant tissue cultures avoidance of dehydration can impose sealing requirements that severely limit the rate of gas exchange in and out of the culture vessel. Conditions within the culture vessel such as the depth of any water cover, the presence of gelling agents, the bulk and porosity of the tissue and the temperature also strongly influence in vitro rates of g...

متن کاملAeration and de-aeration at bottom aeration devices on spillways
Aeration devices are introduced along chute spillways and at bottom outlets to prevent cavitation damage in high velocity flows. Bottom aerators are characterised by large quantities of air entrained along the jet interfaces but also by a strong de-aeration process near the impact of the water jet with the spillway bottom. In this paper, the aeration and de-aeration occurring respectively in th...
متن کاملThe Use of the Selective Inhibitory Action of Toluene on Coliform Bacilli in Routine Cultures.
Benians (1913) demonstrated that all Gramnegative organisms were destroyed by toluene, which had an inhibitory action on diphtheroid bacilli and streptococci but little effect on spores and staphylococci. Webster (1942) suggested the use of toluene to suppress Gram-negative bacilli in mixed broth cultures; he added 10 per cent of toluene to broth cultures, shook them at intervals, and allowed t...
