Mutation of the mupW gene in the mupirocin biosynthetic gene cluster in Pseudomonas fluorescens results in efficient production of a novel pseudomonic acid metabolite, mupirocin W, which lacks the characteristic tetrahydropyran ring, and reveals the role of the mupW gene in pseudomonic acid biosynthesis.

Pseudomonas fluorescens NCIB 11764 was capable of utilizing cyanate (OCN-) as a sole nitrogen source for growth. Crude cell extracts from cells grown on cyanate, but not on ammonium sulfate, were induced for an enzyme catalyzing cyanate conversion to ammonia. Enzymatic activity was shown to be bicarbonate dependent and specific for cyanate as a substrate, suggesting that cyanate utilization in ...

conclusions bacillus thuringiensis is very sensitive to the interaction of p. fluorescens, however is capable to survive in soil due to its capacity of sporulate. some of the cells in the form of spores germinated and folded slightly and remained in a constant cycle of sporulation and germination. this confirms that b. thuringiensis ips82 can germinate, grow and sporulate in soil. results the a...

BACKGROUND Purified water for pharmaceutical purposes must be free of microbial contamination and pyrogens. Even with the additional sanitary and disinfecting treatments applied to the system (sequential operational stages), Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas alcaligenes, Pseudomonas picketti, Flavobacterium aureum, Acinetobacter lowffi and Pseudomonas diminuta were is...

A novel class of antibiotics based on the antimicrobial properties of immune peptides of multicellular organisms is attracting increasing interest as a major weapon against resistant microbes. It has been claimed that cationic antimicrobial peptides exploit fundamental features of the bacterial cell so that resistance is much less likely to evolve than in the case of conventional antibiotics. P...

The growth of Pseudomonas fluorescens (ATCC 11150) on sodium maleate was observed, and the composition of the media was monitored in batch culture. Utilization of the maleate as the sole organic carbon source proceeded by stepwise conversion to fumarate and then to malate. Respiration rates of P. fluorescens on maleate, mixtures of maleate and fumarate salts, and mixtures of maleate and malate ...
