Studies on the Fine Structure of Microorganisms
The fine structure of cells of Saccharomyces cerevisiae engaged in the formation of ascospores was studied in electron micrographs of ultrathin sections. Although the mode of the first reduction division could not be clearly determined, the second nuclear division appeared to proceed in a manner similar to that observed previously during vegetative division. That is, division by constriction of...
متن کاملEffect of cellulose fine structure on kinetics of its digestion by mixed ruminal microorganisms in vitro.
The digestion kinetics of a variety of pure celluloses were examined by using an in vitro assay employing mixed ruminal microflora and a modified detergent extraction procedure to recover residual cellulose. Digestion of all of the celluloses was described by a discontinuous first-order rate equation to yield digestion rate constants and discrete lag times. These kinetic parameters were compare...
متن کاملFine structure of hyperbolic
The main theme of the book Fine Structures of Hyperbolic Diffeomorphisms, by Pinto, Rand and Ferreira, is the rigidity and flexibility of two-dimensional diffeomorphisms on hyperbolic basic sets and properties of invariant measures that are related to the geometry of these invariant sets. In his remarkable article [23], Smale sets the foundations of the modern theory of dynamical systems. He de...
متن کاملFine Structure of Helium
Under the expectation that experiments will soon give values for the 6ne structure intervals of the 2'I" state of helium to an accuracy of 1/10', we have undertaken a program of calculations which, it is hoped, will lead to a new determination of the 6ne-structure constant n. This paper gives a brief survey of the over-all program, and a detailed report of the successful completion of the', 6rs...
متن کاملFine Structure of Mycota
Though the dictyosome of the Golgi apparatus appears to be generally distributed in plant and animal cells, it is here described for the first time in the fungi. The present report illustrates, in electron micrographs of thin sections, the characteristic structure of the Golgi dictyosome in a special cell type of a supporting pseudo-tissue (the inner ectal excipulum) of a highly evolved Ascomyc...
