    Abstract The thylakoids (chromatophores) of the sulfur-free purple bacteria Rhodospirillum rubrum contain 30% lipids soluble in methanol-chloroform, 46% protein, and 14% carbohydrates. 90% of the total sugar content was glucose, 4% fucose, 5% rhamnose. In the thylakoids of Rhodopseudomonas viridis 3,3% sugar was demonstrable (50% glucose, 17% galactose, 15% rhamnose and 17% mannose). 2-keto-3-desoxy-octonate is a structure component in both organisms. After treatment of thylakoids with phenol/water, the main sugar fraction was in the water phase, although in both organisms 3 to 4% of the protein fraction in the phenol phase consists of sugar.

    Abstract The production of bacteriochlorophyll in anaerobic light and dark cultures is strongly inhibited by 2,6-dichlorophenol-indophenol sodium, 4-amino-2-methyl-1-naphthol-hydrochloride and methylene blue. Photophosphorylation is demonstrable 45 min after the start of bacteriochlorophyll synthesis. The induction of bateriochlorophyll synthesis is suppressed by mitomycin if the inhibitor is added together with the process of lowering the oxygen partial pressure. The effect of puromycin is also dependent on the time of addition. Mitomycin and puromycin have no influence on the production of coproporphyrin. In the presence of mitomycin or puromycin and δ-aminolevulinic acid the synthesis of porphyrin is intensely increased but the synthesis of bacteriochlorophyll is blocked. These and other results are interpreted as indicating that control over bacteriochlorophyll synthesis occurs by a gene dependent regulation fo the biosynthesis of those enzymes which are responsible for the production of bacteriochlorophyll from protoporphyrin.

    Abstract Purpose: The use of laparoscopic surgery for colorectal cancer in elderly patients with high comorbidity is a controversial subject. This retrospective analysis aims to compare two different age groups with respect to short and long term clinical and oncological outcomes.
    Methods: All laparoscopic colorectal resections for cancer performed between February 2011 and October 2017 with curative or palliative intention were evaluated.
    Results: Among 128 completed resections, the rate of major complications, length of hospital stays, 30-day mortality, 2-year recurrence rate, and the survival after palliative surgery were comparable between group A (< 75 years; n = 76) and B (≥ 75 years; n = 52). Patients in group B showed an extraordinarily high proportion of ASA III stage (73.1% vs. A: 35.5%; p < 0.01) and, in this context, an increased rate of minor postoperative complications (17.3% vs. A: 6.6%; p < 0.05) and lower overall 2 and 5-year survival rates. Within the first 2 years, they died sooner in the event of recurrence (57.1% vs. A: 18.2%; p < 0.05), and their survival after rectal resection, especially for low rectal carcinoma, was significantly reduced (58.8% vs. A: 96.7%; p < 0.001).
    Conclusion: Laparoscopic surgery for colorectal cancer can be strongly advocated for elderly patients even in the face of high comorbidity. Whether very old patients with low rectal carcinoma also benefit from minimally invasive surgery or should undergo alternative therapies would need to be clarified primarily by examining the quality of life.

    Abstract The growth of purple bacteria is supported either by a photosynthetic, light-dependent electron transfer system or by a respiratory electron transfer system. Both systems are localized in both a cytoplasmic and an intracytoplasmic membrane system. Formation of the functional complexes is regulated by the oxygen partial pressure and light intensity. The organization and the multistep process of assembly of their components will be described in this review. Most details about the assembly of the respiratory complexes are known.

    Abstract Von den Anfängen naturwissenschaftlichen Denkens in der Antike über das Mikroskop bis zur synthetischen Biologie. Mikroorganismen leisten einen wesentlichen Beitrag zum Kreislauf der Stoffe in der Natur. Sie haben die Voraussetzung für das Leben der höheren Organismen geschaffen und synthetisieren wichtige Wirkstoffe wie Vitamine und Antibiotika. Gerhart Drews schildert die Ideengeschichte der Mikrobiologie. Er bringt dem Leser die Welt einiger Denker, Forscher und auch wissbegieriger Laien aus vergangenen Jahrhunderten näher. Er beschreibt so die wesentlichen Entdeckungen, die zur Erkennung der Mikroorganismen, ihrer Rolle in der Natur und bei der Entstehung von Krankheiten geführt haben. In der modernen Zeit schildert er die Entwicklung exemplarisch anhand einzelner Organismen oder Themenfelder, wie z.B. der mikrobiellen Ökologie und Biotechnologie unter Einbeziehung der wesentlichen Entdeckungen in Molekularbiologie und Genetik. Die 2. Auflage enthält ein neues Unterkapitel zu Bakteriengesellschaften des Menschen. Das Unterkapitel zu Hydrothermalquellen der Tiefsee ist um die Einbeziehung des Meeresgrundes erweitert. Lassen Sie sich mitnehmen auf diese faszinierende Zeitreise Die Autoren: Gerhard Drews ist emeritierter Professor am Lehrstuhl für Mikrobiologie an der Universität Freiburg. Georg Fuchs ist Professor am Lehrstuhl für Mikrobiologie an der Universität Freiburg
