Further observations on the fine structure of the haptonema in prymnesium parvumArchiv für Mikrobiologie - Tập 49 - Trang 315-330 - 1964
I. Manton
Information has been provided for the first time on the fine structure of the tip and base of a haptonema, the organism being that already studied in a preliminary way in Manton and Leedale 1963 a. The tip structure is unexpectedly simple, with the haptonema cavity interposed between the rounded apex of the core and the external wall of the organelle. The base has been shown to be unexpectedly com...... hiện toàn bộ
Development of a fluorophore-ribosomal DNA restriction typing method for monitoring structural shifts of microbial communitiesArchiv für Mikrobiologie - Tập 193 - Trang 341-350 - 2011
Tingting Wang, Xiaojun Zhang, Menghui Zhang, Linghua Wang, Liping Zhao
DNA restriction fragment polymorphism technologies such as amplified ribosomal DNA restriction analysis (ARDRA) and terminal restriction fragment length polymorphism (T-RFLP) have been widely used in investigating microbial community structures. However, these methods are limited due to either the low resolution or sensitivity. In this study, a fluorophore-ribosomal DNA restriction typing (f-DRT) ...... hiện toàn bộ
Nickel dependence of factor F430 content in Methanobacterium thermoautotrophicumArchiv für Mikrobiologie - Tập 127 - Trang 273-277 - 1980
Gabriele Diekert, Barbara Weber, Rudolf K. Thauer
Factor F430 is a yellow compound of unknown structure present in methanogenic bacteria. It has recently been shown to contain nickel. In this communication the influence of the nickel concentration in the growth medium on the factor F430 content of Methanobacterium thermoautotrophicum and on the nickel content of factor F430 was studied. It was found: (1) The content of factor F430 in the cells wa...... hiện toàn bộ
Chromatographic and spectroscopic analysis of phycoerythrin 545 and its subunitsArchiv für Mikrobiologie - Tập 135 - Trang 194-198 - 1983
Robert MacColl, Deborah Guard-Friar, Károly Csatorday
Phycoerythrin 545 is a light-harvesting biliprotein isolated from the cryptomonad Rhodomonas lens. Although the absorption spectrum of the native protein suggests that this protein has only phycoerythrobilins for its chromophores, the denaturated protein shows a small near ultraviolet absorption band with a maximum at 333 nm which is not present in phycoerythrobilin. Two methods were employed to s...... hiện toàn bộ
Etudes Cytochimiques et Ultrastructurales de la Paroi de Candida albicansArchiv für Mikrobiologie - Tập 123 - Trang 245-249 - 1979
G. Tronchin, D. Poulain, J. Biguet
La localisation ultrastructurale des polysaccharides paritétaux de Candida albicans a été réalisée par utilisation de Concanavaline A sur sections ultrafines de résine hydrosoluble (glycol méthacrylate). Les sites récepteurs de la lectine sont révélés en incubant successivement les coupes avec de la péroxydase, puis un mélange 3-3′ diaminobenzidine-H2O2. Cette méthode a permis de localiser les man...... hiện toàn bộ
