| Para avaliar o desempenho agronômico da cultura do milho (Zea mays) de segunda safra submetido à inoculação com Pseudomonas fluorescens sob níveis de adubação NPK, um experimento em campo foi conduzido utilizando-se a cultivar de milho híbrido 30F35 cultivada em Latossolo Vermelho eutroférrico. Foram testados seis tratamentos sob o delineamento experimental de blocos casualizados, em esquema fatorial 3 x 2, sendo três níveis de adubação química com NPK (0, 125 e 250 kg ha-1) e dois níveis de inoculante à base de P. fluorescens (com e sem), com quatro repetições. Foram avaliados as características fitométricas, os componentes de produção e a produtividade de grãos do milho. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste... |

| The effect of soil application of biocontrol agents (Pseudomonas fluorescens, Trichoderma viride and T. harzianum) in combination with chitin on induction of phenolics and defense enzymes in coconut roots infected with Ganoderma lucidum, the causal agent of Ganoderma disease, was investigated. Soil application of these biocontrol formulations in combination with chitin induced a significant increase in the activities of peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia-lyase (PAL), chitinase and beta-1,3-glucanase in the G. lucidum infected palms. Activities of both PAL and PO reached maximum levels within 3 d while the activity of PPO reached the maximum level 6 d after application of a mixture of P. fluorescens, T. viride and chitin.... |

| Numerous bacteria coordinate gene expression in response to small signalling molecules in many cases known as acylhomoserine lactones (AHLs), which accumulate as a function of cell density in a process known as quorum sensing. This work aimed to determine if phenotypes that are important to define microbial activity in foods such as biofilm formation, swarming motility and proteolytic activity of two Pseudomonas fluorescens strains, isolated from refrigerated raw milk, are influenced by AHL molecules. The tested P. fluorescens strains did not produce AHL molecules in none of the evaluated media. We found that biofilm formation was dependent on the culture media, but it was not influenced by AHLs. Our results indicate that biofilm formation, swarming... |
