摘要:
The invention relates to lipopeptides with very homologous amino-acid sequences but different fatty acid residues (lipid portion) which are synthesized by Actinoplanes sp. during fermentation and are released into the culture medium, to a process for isolating the lipopeptides from the culture medium and purifying them, to the use of the lipopeptides as pharmacologically active substances, in particular against Gram-positive bacteria, and to Actinoplanes sp. DSM 7358 for producing the abovementioned lipopeptides.

摘要:
The invention relates to a process for the preparation of colorants and/or active compounds by culturing a microorganism of the genus Monascus in a sterilizable fluidized-bed fermenter of low water content, such as was proposed in German Patent Application P 3,625,698.6. The fluidizable particle used here is the microorganism itself--in pellet form or grown on carriers--which can be supplied with nutrients by spraying in substrate solutions. The colorants and/or active compounds are isolated by extraction with organic solvents.
摘要:
The invention relates to the use of a compound of the formula (I) for the treatment of bacterial infections caused by mycobacteria, nocardia or corynebacteria, wherein E is phosphorus; X1, X2 and X3 are oxygen; and R1 and R2 are as defined in the specification.
摘要:
The present invention relates to a novel lantibiotic having the formula NH.sub.2 --R-actagardine, where NH.sub.2 --R is the radical of the amino acid alanine, which is formed by the microorganism Actinoplanes liguriae, DSM 11797 or Actinoplanes garbadiensis, DSM 11796 during fermentation, chemical derivatives of the lantibiotic, a process for its preparation and the use of the lantibiotics as pharmaceuticals.
摘要:
Antifungal polypeptide and process for its productionThe polypeptide with the sequence (SEQ ID NO: 1)Ala-Thr-Tyr-Asn-Gly-Lys-Cys-Tyr-Lys-Lys-Asp-Asn-Ile-Cys-Lys-Tyr-Lys-Ala-Gln-Ser-Gly-Lys-Thr-Ala-Ile-Cys- Lys-Cys-Tyr-Val-Lys-Lys-Cys-Pro-Arg-Asp-Gly-Ala-Lys-Cys-Glu-Phe-Asp-Ser-Tyr-Lys-Gly-Lys-Cys-Tyr-Cyscan be produced by the fermentation of Aspergillus giganteus and used as an antifungal agent.Expression of this polypeptide gene in plants strongly inhibits the growth of phytopathogenic fungi on the plant.
摘要:
It is possible with the aid of various Streptomycetes species to prepare new compounds having a furan or lactone structure. These compounds have a pharmacological, especially antibiotic, action.
摘要:
The compound of the formula ##STR1## in which, independently of one another, R.sup.1 and R.sup.4 are hydrogen or hydroxyl,R.sup.2 and R.sup.3 are hydroxyl,R.sup.5 is hydrogen, hydroxyl or an oxo group, andR.sup.2 and R.sup.3, and R.sup.3 and R.sup.4, can each together form a double bond,has hypolipemic properties and is used for the preparation of a pharmaceutical for lowering serum cholesterol.
