| Study Title | Differences in mycoplasma growth due to different mediums |
| Study Summary | The object is to learn if there are variations in the lipid profiles of the three genomic variants (relative to one another) and if there are difference the lipid profiles due to growth in medium having different supplements. Mycoplasmas are eubacteria, but have only a single plasma membrane and no cell wall. They acquire FAs and cholesterol and other (perhaps many unknown) lipids from the medium which is complex and contains mammalian serum. Various mycoplasma species have been shown to contain a wide spectrum of bacterial lipids, but the composition is unknown for this mycoplasma species. We are particularly interested in ratios of membrane lipids among our strains, in part to gain clues about differences in metabolic pathways pertinent to membrane biogenesisÍž and to predict any underlying features that could relate to the extremely different modes of cell propagation observed among these genomic constructs. |
