Microbes communicate with each other using a wide array of chemical compounds, including volatile organic compounds (VOCs). Usually, such volatile-mediated interactions are studied by growing two different microbes in shared, confined environment and subsequently collecting analyzing the emitted VOCs gas chromatography. This procedure has several drawbacks, artificial overaccumulation potential...

Microbial biofertilizers are becoming an effective tool for sustainable agriculture by means of the reduction of the use of chemical fertilizers. However, the knowledge of each specific plant–microorganism interaction is essential for a correct application. In this study, we analyzed the in vitro plant-growth-promotion mechanisms of a Rhizobium leguminosarum strain named PEPV16 isolated from Ph...

Enterococci are members of the lactic acid bacteria family and are responsible for many food spoilage and fermentations. Some strains of this microorganism are used as probiotics in humans and animals to improve host immunity. However, some Enterococci are important pathogens which cause severe infections. Some strains of Enterococci are resistant to common antibiotic...

Nowadays, population growth, the global temperature increase, and appearance of emerging diseases in important crops generate uncertainty regarding world food security. The use agrochemicals has been “go-to” solution for control phytopathogenic microorganisms, such as Magnaporte oryzae, causing blast disease rice other cereals; Botrytis cinerea, gray mold over 500 plant species; Puccinia spp., ...

Zinnia is an annual plant with the long flowering period from late spring to mid-autumn. It is a popular plant for landscape. In the present study, the effect of two types of growth promoting bacteria and Azolla compost on some ornamental characteristics of Zinnia were evaluated in pot cultivation and greenhouse conditions. The factorial experiment was conducted in three replications based on a...

Nitrogen-fixing, plant-growth promoting bacteria are arguably the biotechnological tool of highest potential to improve agricultural productivity in short term. Nitrogen fixation and phytohormone production by these bacteria have been considered the most important factors for plant growth promotion. However, the underlying mechanisms responsible for productivity increases by associative bacteri...

Enterobacter sp. 638 is an endophytic plant growth promoting gamma-proteobacterium that was isolated from the stem of poplar (Populus trichocarpaxdeltoides cv. H11-11), a potentially important biofuel feed stock plant. The Enterobacter sp. 638 genome sequence reveals the presence of a 4,518,712 bp chromosome and a 157,749 bp plasmid (pENT638-1). Genome annotation and comparative genomics allowe...
