چکیده

An antifungal activity was detected in the culture broth of the myxobacterium, Sorangium cellulosum strain So ce 307. The activity was excreted into the supernatant during the log and early stationary phase. When the organism was fermented in the presence of the adsorber resin XAD-16, the metabolite was quantitatively bound to the resin. The main component, jerangolid A, has structural similarities to ambruticin, which is also produced by strains of Sorangium cellulosum.

The Phosphatomes of the Multicellular Myxobacteria Myxococcus xanthus and Sorangium cellulosum in Comparison with Other Prokaryotic Genomes

BACKGROUND Analysis of the complete genomes from the multicellular myxobacteria Myxococcus xanthus and Sorangium cellulosum identified the highest number of eukaryotic-like protein kinases (ELKs) compared to all other genomes analyzed. High numbers of protein phosphatases (PPs) could therefore be anticipated, as reversible protein phosphorylation is a major regulation mechanism of fundamental b...

Heterologous production of the antifungal polyketide antibiotic soraphen A of Sorangium cellulosum So ce26 in Streptomyces lividans.

The antifungal polyketide soraphen A is produced by the myxobacterium Sorangium cellulosum So ce26. The slow growth, swarming motility and general intransigence of the strain for genetic manipulations make industrial strain development, large-scale fermentation and combinatorial biosynthetic manipulation of the soraphen producer very challenging. To provide a better host for soraphen A producti...

Selection and a 3-Year Field Trial of Sorangium cellulosum KYC 3262 Against Anthracnose in Hot Pepper

KYC 3262 was selected as a biocontrol agent against anthracnose on hot pepper from 813 extracts of myxobacterial isolates. Dual culture with Colletotrichum acutatum and 813 myxobacterial extracts was conducted, and 19 extracts were selected that inhibited germination and mycelial growth of C. acutatum. All selections were Sorangium cellulosum, which are cellulolytic myxobacteria from soil. With...

Unusual outer membrane lipid composition of the gram-negative, lipopolysaccharide-lacking myxobacterium Sorangium cellulosum So ce56.

The gram-negative myxobacterium Sorangium cellulosum So ce56 bears the largest bacterial genome published so far, coding for nearly 10,000 genes. Careful analysis of this genome data revealed that part of the genes coding for the very well conserved biosynthesis of lipopolysaccharides (LPS) are missing in this microbe. Biochemical analysis gave no evidence for the presence of LPS in the membran...
