Globule walls

Identification When examined under a microscope, a sample exhibits numerous irregular masses and isolated yeast cells—the latter ovate, elliptical, spheroidal, or elliptic-elongate in shape, some with one or more attached buds—up to 12 pun in length and up to 7.5 xm in width. Each has a wall of cellulose surrounding a protoplast containing refractile glycogen vacuoles and oil globules. 

Membrane crystals are monoclinic prisms, each of which is surrounded by a wall or membrane. In the process of formation a crystal first is formed in the cell sap and then numerous oil globules make their appearance in the protoplasm surrounding it later some of the walls of the cell grow around the crystal and completely envelop it. 

Stored extracellularly or intracellularly. Van Gemerden however suggested that the location of the electron acceptor in the HS oxidation step determines whether sulfur is stored extracellularly or intracellularly [46] as is explained in Fig. 8. This is supported by research of Then and Triiper [8] on sulfide oxidation in Halorhodospira abdelmalekii, excreting sulfur globules extracellularly. They showed the cytochrome c-551 to have a catalytic effect on the oxidation of sulfide and to be located on the outside of the cell membrane. In Al. vinosum cytochrome c-551 is located in the periplasmic space, the space between the outer cell wall and the cytoplasmic membrane, which is also the location of storage of sulfur globules [47]. 

Thin-film metal (metal oxide)/polymer nanocomposites with different inorganic phase contents were obtained by using the cold-wall vacuum co-deposition technique. A range of metals was shown to be applicable to form nanocomposite thin films with PPX, i.e., Al, Ti, Pd, and Sn. AFM studies show the metal nanoparticles to have a size of 7-50 nm. Within the composite the polymer forms more or less spherical globules with a maximum size of about 200 nm. The interfacial regions between neighbouring polymeric spherulites contain nanoparticles of the inorganic filler.
