Description
Die Erfindung betrifft eine Verbindung antibiotischer Aktivität, ein Verfahren zu ihrer Herstellung sowie ein Mittel mit der Ver bindung.The invention relates to a compound of antibiotic activity, a process for their preparation and an agent with the Ver binding.
-
A.1. Produzierende Kultur:
Das Myxobakterium Chondromyces crocatus, Stamm Cm c3, Un terordnung Sorangineae, Ordnung Myxococcales mit einem unbekannten Begleitbakterium in Form kleiner Stäbchen.A.1. Producing culture:
The myxobacterium Chondromyces crocatus, strain Cm c3, suborder Sorangineae, order Myxococcales with an unknown accompanying bacterium in the form of small rods. - A.2. Herkunft der produzierenden Mischkultur: Isoliert an der GBF im Juni 1985 aus einer Bodenprobe von Madeira.A.2. Origin of the producing mixed culture: Isolated at the GBF in June 1985 from a soil sample from Madeira.
-
A.3. Beschreibung der produzierenden Mischkultur:
- A.3.1. Die vegetativen Zellen von Cm c3 sind zylindrisch mit breit abgerundeten Enden, 0,8×6 bis 8 µm. Auf festen Nährboden wächst der Organismus in Gegenwart des Begleitbakteriums gut auf Hefeagar, z. B. VY/2-Agar (Backhefe 0,5%, bezogen auf Frischgewicht; CaCl₂·2H₂O 0,1%, Cyanocobalamin 0,5 mg/l, Agar 1,5%; pH 7,2). Auf reinen Glucose-Mineralsalz-Medien ist kein Wachstum zu beobachten. Proteine, z. B. Casein oder Einzellerprotein, werden hydrolysiert. Chitin wird nicht angegriffen. Der Stamm wächst bevorzugt bei 30°C, im neutralen pH-Bereich und aerob. Auf geeignetem Nährboden breitet sich die Ko lonie allmählich über die Kulturplatte aus. Auf der Ober fläche bilden sich kurze breite radiale Gräben. Sind He fezellen im Nährboden vorhanden, werden sie weitgehend abgebaut. Nach einigen Tagen können Fruchtkörper entste hen: Diese bestehen aus orangefarbenen Sporangiolen (von etwa 20 bis 30 µm Durchmesser und 30 bis 45 µm Länge) die auf einem verzweigten weißen Stiel sitzen. Im Innern fin det man Myxosporen, die morphologisch den vegetativen Zellen sehr ähneln, physiologisch aber trocknungsresi stende Ruhezellen darstellen.
- In Flüssigmedien wächst der Stamm in kleinen Zellklümp chen, sowohl in Schüttelkolben bei 160 U/min (100 ml Me dium in 250-ml-Erlenmeyerkolben bzw. 400 ml Medium in 1000 ml Erlenmeyerkolben) als auch in Bioreaktoren (gete stet bis zum 300-l-Maßstab). Als Kulturmedium ist z. B. Pol 1-Medium geeignet: Probion PS (Einzellerprotein aus Methylomonas clarae; Hoechst, Frankfurt) 0,4%; Stärke 0,3%; MgSO₄·7H₂O 0,1%; CaCl₂·2H₂O 0,05%; 1 ml/l Stan dard-Spurenelementlösung und 1 ml/l Standardvitaminlösung (beides Schlegel, Allgemeine Mikrobiologie); pH 7,0. Die Kulturen werden bei 30 C über 3 bis 4 Tage gehalten. Der Stamm wächst auch gut auf der Basis von Sojamehl. Nach Abtrennung des unten beschriebenen Begleitbakteriums wächst der Stamm Cm c3 jedoch wesentlich schlechter und lysiert nach einigen Passagen.
- Cm c3 läßt sich konservieren: z. B. durch Einfrieren ve getativer Zellen von Agarplatten oder Flüssigkulturen in Peptonlösung bei -80 ,C oder im flüssigen Stickstoff.
- A.3.2 Bei dem Begleitbakterium von Chondromyces crocatus, Stamm Cm c3 handelt es sich um ein pleiomorphes gramnegatives Stäbchen. Es läßt sich durch Ausstreichen der Mischkultur auf Komplettnährböden, z. B. Nutrient Agar, von Stamm Cm c3 abtrennen. Das Bakterium wächst auf Nutrient Agar nur langsam, und nach ca. 1 Woche beobachtet man einen schwach rötlichen Film im Bereich des Ausstrichs. In den unter A.3.1. genannten Flüssigmedien vermehrt sich das Bakterium in etwa parallel zu Stamm Cm c3.
- A.3.1. The vegetative cells of Cm c3 are cylindrical with broadly rounded ends, 0.8 × 6 to 8 μm. On solid medium, the organism grows well on Hefeagar in the presence of the accompanying bacterium, z. B. VY / 2 agar (yeast 0.5%, based on fresh weight, CaCl₂ · 2H₂O 0.1%, cyanocobalamin 0.5 mg / l, agar 1.5%, pH 7.2). Growth is not observed on pure glucose-mineral salt media. Proteins, e.g. As casein or protozoan protein are hydrolyzed. Chitin is not attacked. The strain preferably grows at 30 ° C, in the neutral pH range and aerobic. On suitable nutrient medium, the colony gradually spreads over the culture plate. On the upper surface form short wide radial trenches. If yeast cells are present in the nutrient medium, they are largely degraded. After a few days fruiting bodies may appear: These consist of orange sporangioles (about 20 to 30 μm in diameter and 30 to 45 μm in length) that sit on a branched white stalk. Inside, myxospores are found, which, in morphological terms, are very similar to vegetative cells, but physiologically represent dehydration-resistant resting cells.
- In liquid media, the strain grows in small Zellklümp chen chen, both in shake flasks at 160 U / min (100 ml Me dium in 250 ml Erlenmeyer flask or 400 ml medium in 1000 ml Erlenmeyer flasks) and in bioreactors (gete stet until 300- l scale). As a culture medium is z. B. Pol 1 medium suitable: Probion PS (single-celled protein from Methylomonas clarae; Hoechst, Frankfurt) 0.4%; Thickness 0.3%; MgSO₄ · 7H₂O 0.1%; CaCl₂ · 2H₂O 0.05%; 1 ml / l standard trace element solution and 1 ml / l standard vitamin solution (both Schlegel, General Microbiology); pH 7.0. The cultures are maintained at 30 C for 3 to 4 days. The strain also grows well on the basis of soybean meal. After separation of the accompanying bacterium described below, the strain Cm c3 grows much worse and lysed after a few passages.
- Cm c3 can be conserved: z. By freezing viable cells of agar plates or liquid cultures in peptone solution at -80, C or in liquid nitrogen.
- A.3.2 The accompanying bacterium of Chondromyces crocatus, strain Cm c3, is a pleiomorphic gram-negative rod. It can be determined by spreading the mixed culture on complete nutrient media, eg. Nutrient agar, from strain Cm c3. The bacterium grows slowly on nutrient agar, and after about 1 week a slightly reddish film is observed near the smear. In the under A.3.1. The bacteria increase in approximately parallel to strain Cm c3.
- A.4. Zugänglichkeit der Mischkultur: Cm c3 (+ Begleitbakte rium) ist bei der Deutschen Sammlung von Mikroorganismen (DSM) in Braunschweig unter der Nr. DSM 8227 hinterlegt.A.4. Accessibility of mixed culture: Cm c3 (+ accompanying c rium) is in the German Collection of Microorganisms (DSM) in Braunschweig under the number DSM 8227 deposited.

Aliquote der konzentrierten Extrakte werden im Agardiffusionstest gegen Pilze getestet. Im dünnschichtchromatischen Test wird Crocacin im Vergleich mit isolierter Reinsubstanz identifiziert. Die Aufarbei tung, Isolierung und Charakterisierung erfolgt gemäß Ab schnitt B.A.5. Evidence of Crocacin: For the qualitative detection of Crocacin become cell masses of the producing culture Extracted acetone. Aliquots of concentrated extracts are tested in agar diffusion test against fungi. in the Thin-layer chromatographic test is compared to Crocacin identified with isolated pure substance. The Aufarbei tion, isolation and characterization according to Ab cut B.
