Biomimetic membranes (BMM) based on polymer filters impregnated with lipids or their analogues are widely applied in numerous areas of physics, biology, and medicine. In this paper we report the design and testing of an electrochemical system, which allows the investigation of CO2 transport through natural membranes such as alveoli barrier membrane system and also can be applied for solid-state measurements. The experimental setup comprises a specially designed two-compartment cell with BMM connected with an electrochemical workstation placed in a Faraday cage, two PH meters, and a nondispersive infrared gas analyzer. We prove, experimentally, that the CO2 transport through the natural membranes under different conditions depends on pH and displays a similar behavior as natural membranes. The influence of different drugs on the CO2 transport process through such membranes is discussed.

Acinetobacter Sp

Acinetobacter sp. HO-1-N, a gram-negative hydrocarbon oxidizing bacterium previously designated Micrococcus cerificans, has been shown to sequester the hydrocarbon into intracytoplasmic pools as a result of growth on this substrate. In hydrocarbon grown cells, an intracytoplasmic membrane system was also observed along with a doubling of cellular phospholipids (Z). However, using conventional dehydration and embedding procedures in preparing thin sectioned material, the hydrocarbon is extracted from the cells. This may lead to structural distortion, consequently, the freeze-etch technique was applied to preserve the integrity of the cell.

Potassium permanganate has been used as a fixative for the botanical specimen and membrane system in thin section by Glauert (1975). A new potassium permanganate fixative ( Trisodium citrate 60mM, Potassium chloride 25mM, Magnesium chloride 35mM, and Potassium permanganate 125mM ) for localizing membranous system in whole_mount cultured cells with standard trasmission electron microscopy and phase_contrast microscopy has been developed). Here, we report that using this new potassium permanganate fixative for membranous system in sections.Cultured cells, CV_1 (African green monkey kidney epithelial cells), Balb/c 3T3 ( Mouse embryo fibroblast ) and MCF_7 (Human adenocarcinoma cell line) were used for this study. All cells were grown on 35mm plastic dishes in DME medium containing 5% calf serum at 37 c with 100% humidity and 5% CO2. Using the potassium permanganate fixative to fix the cells for about 7 minutes. After fixation, the cells were dehydrated in a graded series of ethanol.
