Zum Abbau von 14C-markierter �pfels�ure durch Bacterium gracile

1962

Der Apfelsaureabbau durch B. gracile wird mit Hilfe 14C-markierter Sauren quantitativ untersucht. Die nach dem Abbau wiedergefundene Aktivitat in Restapfelsaure, Milchsaure und Kohlendioxyd betragt zusammen 96–97% der Aktivitat der eingesetzten dl-Apfelsaure-[1,4-14C2]. Die molaren Verhaltnisse von abgebauter Apfelsaure zu Milchsaure und Kohlendioxyd sind 1:1:0,9. Ein Weiterabbau der Apfelsaure uber Milchsaure hinaus ist zu verneinen, da in diesem Fall mehr Kohlendioxyd entstehen muste als dem Verhaltnis 1:1:1 entsprache. D-Apfelsaure und Fumarsaure werden von den Bakterien ebenfalls dissimiliert, Milchsaure wird nicht angegriffen. Citronensaure-[1,5-14C2] wird sehr langsam abgebaut; als ei…

Malic-Enzym-Synthese und pH-Adaptation bei L-�pfels�ure abbauenden Bakterien

1968

Es wird die Malic-Enzym-Synthese bei sechs verschiedenen Arten L-Apfelsaure abbauender Bakterien untersucht. Die homofermentativen Arten bilden unter den gepruften Bedingungen ausschlieslich ein adaptives Malic-Enzym, wahrend die Synthese bei den heterofermentativen in Abhangigkeit vom Zuchtungsmilieu adaptiv oder konstitutiv erfolgen kann. Beim konstitutiven Malic-Enzym ist der sonst positive Glucose-Effekt auf Aktivitat und Induktion nicht festzustellen, wie Versuche mit Enzymlosungen ergeben haben. Die pH-Maxima der Apfelsaureabbau-Aktivitat der intakten Bakterien verschieben sich bei Gewohnung der Zellen an hohere H+-Ionen-Konzentrationen im kunstlichen und naturlichen Milieu zu tiefer …

Influence of bacteria on the metabolite pattern of phenol in zebra fish (Brachydanio rerio)

1989

Summary An investigation was performed on the potential influence of bacteria in the medium on the metabolism of phenol in zebra fish. The results obtained in vitro and in vivo show that bacteria may influence biotransformation studies of xenobiotics by fish in different manner. First, it was shown that phenol conjugates were deconjugated. Hydrolysis of phenyl glucuronide was observed both in vitro and in vivo. Deconjugation of phenyl sulphate was found to a minor extent merely under in vitro conditions. Second, the xenobiotic itself, in this case phenol, was degradated to CO2. The proportion did not lead to a significant removal of the test compound of the fish. Zusammenfassung Einflus von…

Phenazine antibiotics produced by fluorescent pseudomonads contribute to natural soil suppressiveness to Fusarium wilt

2009

Natural disease-suppressive soils provide an untapped resource for the discovery of novel beneficial microorganisms and traits. For most suppressive soils, however, the consortia of microorganisms and mechanisms involved in pathogen control are unknown. To date, soil suppressiveness to Fusarium wilt disease has been ascribed to carbon and iron competition between pathogenic Fusarium oxysporum and resident non-pathogenic F. oxysporum and fluorescent pseudomonads. In this study, the role of bacterial antibiosis in Fusarium wilt suppressiveness was assessed by comparing the densities, diversity and activity of fluorescent Pseudomonas species producing 2,4-diacetylphloroglucinol (DAPG) (phlD+) …

(+)-(E)-Chrysanthenyl Acetate: A Molecule with Interesting Biological Properties Contained in the Anthemis secundiramea (Asteraceae) Flowers

2020

Anthemis secundiramea is a perennial herb native widespread throughout the Mediterranean basin. The oil obtained from the flowers of this plant has antimicrobial properties against gram-positive and -negative bacteria, and inhibits the biofilm formation. The extract of A. secundiramea also has antioxidant activity&mdash
