Cellophane Membranes
A cellophane membrane has proved a simple device for separating the L variant of Streptobacillus moniliformis from the bacterial form, as reported by P6rezMiravete and Calder6n (1956). When a culture was inoculated on cellophane resting on clear medium, they observed the development of the L type colonies only on the agar, whereas bacterial growth flourished on the surface of the cellophane. It...
متن کاملIonic Transference Numbers in Cellophane Membranes
The "apparent" cation transference number within cellophane is determined for HCl, KCl, NH(4)Cl, NaCl, and LiCl. The method consists in measuring the E.M.F. in a concentration chain employing Ag:AgCl electrodes or calomel electrodes and calculating from formulas derived for cases of simple, unconstrained diffusion. The transference numbers and the cation mobilities relative to the chloride ion ...
متن کاملPlasmid transformation in Haemophilus influenzae.
Purified 34-megadalton-plasmid deoxyribonucleic acid from antibiotic-resistant strains of Haemophilus influenzae transforms competent strains of H. influenzae more efficiently if the recipient strains contain certain other 30-megadalton plasmids.

متن کاملElectrical Factors Influencing the Rate of Filtration of Aqueous Electrolyte Solutions through Cellophane Membranes
The mechanisms by which electrokinetic factors might influence the filtration rate of aqueous electrolyte solutions through membranes are discussed. The filtration rate of a thorium chloride solution in which the membrane is isoelectric is compared with those of other solutions. The maximum filtration rate is found at the isoelectric concentration, the rate falling as the electrokinetic potenti...
