Abstract

Aus Blasia pusilla-Blattohren isolierte Nostoc sphaericum-Lager wurden u.a. auch in verschiedenen stickstofffreien Nahrlosungen rein kultiviert. Die Algen wuchsen hierin bei Zimmertemperatur und ohne Zusatzbeleuchtung gut. Der Stickstoffgehalt wurde nach 90 und 140 Tagen an durch UV-Bestrahlung (4 min, 30 cm Abstand) erhaltenen bakterienfreien Kulturen ermittelt. Mit Hilfe der Mikro-Kjeldahl-Methode liesen sich in 10 ml Kulturflussigkeit (mit Algen) durchschnittlich 0,615 bzw. 1,05 mg Stickstoff nachweisen. Danach ist Nostoc sphaericum entgegen anderslautenden Ausfuhrungen von Lhotsky (1946) doch befahight, atmospharischen Stickstoff zu binden, wie dies schon Molisch (1925 und 1926) und Vouk u. Wellisch (1931) behaupteten.
