Many strains of Pseudomonas fluorescens show potential for biological control of phytopathogens especially root pathogens. In taxonomic terms, several of them are indeed P. fluorescens sensu stricto, while others belong in fact to neighbouring species of the 'P. fluorescens' complex or to ill-defined related species within the fluorescent Pseudomonas spp. These bacteria have become prominent mo...

Olive mill wastewater polyphenol extract was tested for antimicrobial activity against 64 strains of Pseudomonas fluorescens responsible for mozzarella discolouration. The extract showed a minimum inhibitory concentration (MIC)50 value of 5 mg/mL and a MIC90 value of 7 mg/mL. The MBC50 and MBC90 values corresponded to 6 and 8 mg/mL, respectively. The MIC concentration (7 mg/mL) was demonstrated...

A mixed culture of Pseudomonas fluorescens BS2 and Pusillimonas noertemannii BS8 degraded poly-γ-d-glutamic acid; when the 2 strains were cultured separately, no hydrolytic activity was apparent. Here we report the draft genome sequences of both soil isolates.

We report here the first draft genome sequences of Pseudomonas fluorescens strains that have been isolated from humans. The seven assembled draft genomes contained an average of 60.1% G+C content, were an average genomic size of 6.3 Mbp, and mapped by multilocus sequence analysis to subclade III.

The Pseudomonas genus contains a metabolically versatile group of organisms that are known to occupy numerous ecological niches, including the rhizosphere and endosphere of many plants. Their diversity influences the phylogenetic diversity and heterogeneity of these communities. On the basis of average amino acid identity, comparative genome analysis of >1,000 Pseudomonas genomes, including 21 ...

A bacterial strain was isolated from a wastewater lagoon and identified as Pseudomonas fluorescens. This isolate was able to utilize linalool as a sole carbon and energy source. The ability was found to be encoded on a 60-megadalton transmissible plasmid, pSRQ60. The plasmid was also mated into a commercial waste treatment strain, which expanded its ability to utilize other isoprenoid compounds.

Fungal chitin metabolism involves diverse processes such as metabolically active cell wall maintenance, basic nutrition, and different aspects of virulence. Chitinases are enzymes belonging to the glycoside hydrolase family 18 (GH18) and 19 (GH19) and are responsible for the hydrolysis of β-1,4-linkages in chitin. This linear homopolymer of N-acetyl-β-D-glucosamine is an essential constituent o...

The Green Revolution led to an increased use of synthetic pesticides, causing environmental pollution. As alternative, biopesticides made from entomopathogenic agents such as fungi have been sought. This study aimed design and evaluate the performance a harvester machine for efficiently collecting spores Metarhizium anisopliae Beauveria bassiana grown on rice corn substrates. spore yield was es...
