    摘要: The present invention provides female sex hormone degrading bacteria belonging to the genus Novosphingobium , Sphingomonas or Ochrobactrum and having at least one of the property (a) the ability to degrade at least ethynylestradiol; the property (b) the ability to degrade at least 17β-estradiol and/or estrone, and having a degradation rate constant k 1 for 17β-estradiol and/or estrone of 0.05 or more; and the property (c) the ability to degrade at least 17β-estradiol and/or estrone, and having the ability to decrease the concentration of 17β-estradiol and/or estrone, contained in wastewater, to less than 10 ng/L. These bacteria can efficiently degrade various female sex hormones, including recalcitrant synthetic female sex hormones, to such very low concentrations as not to affect the environment, and can easily be cultured and proliferated.

    摘要: The present invention provides a method of proliferating a microorganism capable of degrading a hard-to-degrade organic compound, comprising proliferating at least one microorganism capable of degrading a hard-to-degrade organic compound selected from the group consisting of Janibacter genus, Pseudomonas genus, Rhodococcus genus, Desulfomonile genus, Alcaligenes genus, Bacillus genus, Streptococcus genus, Acinetobacter genus, Achromobacter genus, Paracoccus genus, Rhodobacter genus, Rhodobacterium genus, Methylosinus genus, Mycobacterium genus, Nitrosomonas genus, Corynebacterium genus, and Methanotrophs, in a culture medium containing both a substance capable of inducing the degradation capability of the microorganism and Fe ions, under inorganic conditions. The present invention also provides a method of degrading a hard-to-degrade organic compound by using a microorganism capable of degrading the hard-to-degrade organic compound, comprising a step of controlling the degradation capability of the microorganism by adjusting the concentration of Fe ions in the culture medium.

    摘要: Die Erfindung betrifft ein Stoffgemisch zur Verwendung als Nährstoffsubstrat für Mikroorganismen bei der biologischen Bodensanierung, insbesondere dem mikrobiologischen Abbau von Kohlenwasserstoffen.
    Das Stoffgemisch besteht aus einem Polymergemisch unterschiedlicher Methylen-Harnstoff-Kondensate mit vorwiegend einfachem Monomercharakter entsprechend Methylen-Diharnstoff und Dimethylen-Triharnstoff und Kondensaten mit komplexerem Monomercharakter entsprechend Trimethylen-Tetraharnstoff und Tetramethylen-Pentaharnstoff.
    Besonders günstig wird das erfindungsgemäße Stoffgemisch als Suspension ausgebildet und in die Böden eingebracht.
