Zusammenfassung Markiertes Glycin und Serin wurde in Ferrichrom, Ferricrocin und Ferrichrysin von vier Stämmen der Gattung Aspergillus zu 1,6–11,8% in vivo eingebaut. Von Aspergillus fumigatus und A. quadricinctus wurden zellfreie Extrakte hergestellt, die Cyclohexapeptide synthetisieren können.
Incorporation of glycine and serine in sideramines of the ferrichrome type with fungi of the genus Aspergillus in vivo and in vitro
A 1.6–11.8% incorporation of labelled glycine and serine into ferrichrome, ferricrocin and ferrichrysin has been achieved with four strains of Aspergillus in vivo. Cell-free extracts of Aspergillus fumigatus and A. quadricinctus capable of cyclohexapeptide biosynthesis have been prepared.

Zusammenfassung Auf Grund der physiologischen Merkmale einer in Paramecium bursaria Ehrbg. auftretenden Chlorella ergibt sich eine systematische Zuordnung in den Formenkreis um Chlorella vulgaris f. tertia Fott et Nováková und Chlorella vulgaris var. vulgaris Beijerinck. Hiervon abweichende Befunde anderer Autoren werden diskutiert.
On the taxonomy of an auxotrophic Chlorella isolated from Paramecium bursaria ehrbg
An auxotrophic Chlorella has been isolated from Paramecium bursaria Ehrbg. and cultivated in mass culture in an inorganic medium supplied with vitamins B1 and B12. With regard to its physiological properties it is not identical with either one of the so far known Chlorella species. It belongs, however, to the group of Chlorella vulgaris f. tertia Fott et Novaková and Chlorella vulgaris var. vulgaris Beijerinck.

Zusammenfassung Anhand der Retzius-Streifen und der Doppelbrechung wird bei urodelen (Megalobatrachus japonicus) und anuren (Rana catesbyana) Amphibien die Anwesenheit von Zahnschmelz nachgewiesen; er überzieht als zusammenhängende Kappe den distalen Abschnitt des zweispitzigen Zahnes.
Enamel structure in urodela and anura
Summary The presence of enamel on urodele (Megalobatrachus japonicus) and anuran (Rana catesbyana) teeth has been shown by birefringence and the identification of the stripes (lines) of Retzius. The enamel forms a continuous cap on the distal part of the bicuspid teeth.

Zusammenfassung Ein asporogener Stamm vonSaccharomyces cerevisiae und sechs Stämme vonLactobacillus brevis bildeten in einem vollsynthetischen Medium Butanol-2 aus Butandiol-2,3. Hierbei wurde meso-Butandiol-2,3 verbraucht. Die verschiedenen Lactobacillen bilden unterschiedliche Mengen an Butanol-2 (bis 810 mg/l).
On the formation of butanol-2 by lactic acid bacteria and yeast
Butanol-2 was formed from butanediol-2,3 in a synthetic medium by an asporogenous strain ofSaccharomyces cerevisiae and 6 strains ofLactobacillus brevis. The mesoform of butanediol-2,3 is degraded to butanol-2. The lactic acid bacteria form different amounts of butanol-2 (up to 810 mg/l).

Zusammenfassung Gamonbildung und Carotinsynthese sind bei den Zygomyceten Mucor mucedo, Blakeslea trispora und Phycomyces Blakesleeanus gekoppelte Reaktionen. Die Gamonbildung verläuft parallel zur Carotinbiosynthese. Damit kann ein Weg zur Klärung der Gamonsynthese gefunden werden.
Sexual reaction and carotene synthesis in Zygomycetes
Summary In the Zygomycetes Mucor mucedo, Blakeslea trispora and Phycomyces Blakesleeanus, gamon formation and carotene synthesis are coupled reactions. The gamon formation goes parallel with the carotene biosynthesis. This provides a way by which gamon synthesis can be elucidated.

If exsiccated trichomes ofPseudanabaena galeata are immersed in water, striking changes occur as a consequence of lysis and maceration. The locomotion of living trichomes differs from that inOscillatoriaceae. This and other differences make it doubtful, whetherPs. galeata belongs to theOscillatoriaceae; at any rate it occupies an aberrant position.

25 populations from Turkey and one of Syria belonging to theSabulina section of the genusMinuartia have been karyologically examined. New chromosome numbers have been recorded forM. mesogitana andM. hybrida subsp.turcica, and a new variety was found in theM. hybrida complex. The origin of the taxa with n = 23 and n = 35 is discussed.
