Electron microscopy of cellular division in Sarcina lutea.
Electron micrographs of sections of dividing cells of bacteria have been (lescribed in several papers. In one report, Chapman and Hillier (1953) described the formation in Bacillus cereus of a transverse cell wall by the centripetal growth of a ring of cell wall material. No cytoplasmic membrane was observed in these cells. In another report, Chapman (1959b) described the formation in an uniden...
متن کاملFine structure of Sarcina maxima and Sarcina ventriculi.
The fine structure of Sarcina maxima and S. ventriculi was studied by electron and phase-contrast microscopy. The two organisms differ mainly with respect to their cell surface. A thick cellulose layer present on the cell wall of S. ventriculi was not observed on the surface of S. maxima. Carbon replication indicated that the outer surface of S. ventriculi is rough in contour, probably as the r...
متن کاملPyruvate metabolism in Sarcina maxima.
The mechanisms of pyruvate cleavage and hydrogen production by Sarcina maxima were studied. It was found that a phosphoroclastic system for pyruvate oxidation, similar to that occurring in saccharolytic clostridia, is present in S. maxima. Cleavage of pyruvate by extracts of the latter organism resulted in the formation of acetyl phosphate, CO(2), and electrons which were transferred to ferredo...
متن کاملCell division in Aspergillus.
Amenable to sophisticated genetic and molecular analysis, the simple filamentous fungus Aspergillus nidulans has provided some novel insights into the mechanisms and regulation of cell division. Mutational analysis has identified over fifty genes necessary for nuclear division, nuclear movement and cytokinesis. Molecular and cellular analysis of these mutants has led to the discovery of novel c...
