Abstract:
The present invention provides methods for the isolation of a new group of actinomycetes and for the identification of members of this group based on characteristic nucleotide sequences and phylogenetic analyses. This group is phylogenetically distinct from all other known actinomycetes and represents a novel genus that includes multiple new species. Members of this group can be recognized by signature MAR2 nucleotides present in their 16S rRNA gene sequences and by standard phylogenetic treeing methods.
Abstract:
A novel family of cyclic polyene natural products isolated from marine actinomycete strain CNQ 140 is provided. This novel strain of actinomycetes was obtained from a previously unstudied population of marine actinomycetes that reside in sediments off La Jolla, California. Compounds derived from strain CNQ 140 have been characterized as having a cyclic polyene-polyol structure; a molecular weight from about 996 to about 1010 in the core ring structure; and at least 58 carbons and at least 14 oxygens. The invention compounds have antitumor and/or anti-microbial activity.
Abstract:
This invention provides a method for discovery of new lantibiotic pathways by mining available sequence information and by exploiting conserved regions in lantibiotic biosynthetic enzymes to design probes and PCR primers for analysis of un-studied organisms. We have found that lantibiotic biosynthetic enzymes are broadly distributed in Gram-positive. New pathways are being cloned and sequenced and their lantibiotic products are being defined and disclosed.
Abstract:
The present invention relates to method of liquefying starch-containing material, wherein starch-containing material is subjected to a bacterial alpha-amylase at (a) a temperature around 50-80°C for 10-180 minutes, followed by (b) treatment at a higher temperature than used in step (a) for 1-60 minutes.
Abstract:
Genes and proteins involved in the biosynthesis of benzodiazepines by microorganisms, including the genes and proteins forming the biosynthetic loci for the benzodiazepine anthramycin from Streptomyces refuineus subsp. thermotolerans. The genes and proteins allow direct manipulation of benzodiazepines and related chemical structures via chemical engineering of the enzymes involved in the biosynthesis of anthramycin.
Abstract:
The present invention is directed to a method for producing a new nematocidal composition particularly useful against plant parasitic nematodes and also a process to prevent damage resulting from nematode infestation. The method for production of the composition involves heating a pH-adjusted fermentation broth of microorganisms to a temperature of at least about 100 DEG C for at least about 15 minutes. Preferably, the microorganism is Gibberella fujikuroi, Streptomyces erythraeus, Bacillus sphaericus, Bacillus thuringiensis or Fusarium moniliforme .
Abstract:
The present invention is directed to isolated transducing phages, methods of isolating transducing phages, and methods of using transducing phages including, for instance, transferring at least one nucleic acid fragment from a donor microbe to a recipient microbe, and producing a secondary metabolite from a microbe. The transducing phages typically have a broad host range, and transduce microbes in the Order Actinomycetales, in particular in the Family Streptomycetaceae, including Streptomyces coelicolor, Streptomyces lividans, Streptomyces venezuelae, Streptomyces avermitilis, and Saccharopolyspora erythraea. The transducing phages can be specialized transducing phages or generalized transducing phages.
Abstract:
The present invention relates to a novel glucose-6-phosphate translocase inhibitor L 970871, which is produced by an Actinomycete sp. (culture number HIL-007997) during fermentation, a process for its preparation, to chemical derivatives derived from compound L 970871, to the use of compound L 970871 and derivatives derived therefrom and pharmacological active substances, as medicament and, in particular, for the treatment of diabetes mellitus, and to an Actinomycete sp. HIL-007997(DSM 11993) for producing the abovementioned compound L 970871.
Abstract:
A biophysically derived yeast preparation is proposed which stimulates respiration in liver homogenate, contains an L-amino acid oxidase inhibiting factor, and exhibits excellent cicatrization properties and RES-stimulating action. The process for manufacturing the yield preparation consists in treating an initial yeast, if necessary with addition of a liquid support, until a light resuspended material is obtained, followed by a brief thermal shock treatment until gases are evolved by fermentation. In addition, fodder and plant hormone solutions containing these biophysically derived yeasts are proposed.
Abstract:
Aspects of the invention provide methods for producing one or more secondary metabolites from microbial culture. In various embodiments, the method comprises culturing a microbial cell producing a secondary metabolite for recovery from a bioreactor medium, the medium comprising an aqueous phase and an extraction phase. The composition of the extraction phase, and the relevant amount with respect to the aqueous phase, enhances production of the secondary metabolite from microbial cells and/or enhances extracellular transfer of the metabolite.
