| microbial diversity observed during hemp retting. | historically used in textile and paper industry, hemp fibres have started to find new applications in composite materials with important economic and ecological advantages. however, their applications are limited since manufacturers have some difficulties to standardise fabrication processes. this study is a first step before selection and isolation of strains that could later be used to optimise microbial retting efficiency and hence fibre quality. we studied six samples harvested on different ... | 2015 | 25575888 |
| selection of a biocontrol agent based on a potential mechanism of action: degradation of nicotinic acid, a growth factor essential for erwinia amylovora. | this work describes a medium-based screening method for selecting microbial biocontrol agents against erwinia amylovora based on the degradation of a specific growth factor. erwinia amylovora, the causal agent of the devastating fire blight disease, requires nicotinic acid or nicotinamide as an essential growth factor. potential biocontrol agents are either selected for antimicrobial production in plate or directly on immature pears or apple blossoms. in this work, we have attempted to streamlin ... | 2010 | 21404214 |
| epiphytic microorganisms on strawberry plants (fragaria ananassa cv. elsanta): identification of bacterial isolates and analysis of their interaction with leaf surfaces. | epiphytic bacteria were isolated from strawberry plants cultivated in the field or in the greenhouse in order to investigate their interaction with leaf-surface transport properties. colonization of lower leaf sides was higher on field-grown plants, whereas upper leaf sides were more densely colonized on plants cultivated in the greenhouse. fungal isolates significantly contributed to total microbial biomass on leaf surfaces of greenhouse-grown strawberry plants, whereas these organisms were rar ... | 2005 | 16329966 |
| pseudomonas lutea sp. nov., a novel phosphate-solubilizing bacterium isolated from the rhizosphere of grasses. | a phosphate-solubilizing bacterial strain designated ok2(t) was isolated from rhizospheric soil of grasses growing spontaneously in a soil from spain. cells of the strain were gram-negative, strictly aerobic, rod-shaped and motile. phylogenetic analysis of the 16s rrna gene indicated that this bacterium belongs to the gamma-subclass of proteobacteria within the genus pseudomonas and that the closest related species is pseudomonas graminis. the strain produced catalase but not oxidase. cellulose, ... | 2004 | 15143034 |
| pseudomonas rhizosphaerae sp. nov., a novel species that actively solubilizes phosphate in vitro. | a bacterial strain (designated ih5(t)), isolated from rhizospheric soil of grasses growing spontaneously in spanish soil, actively solubilized phosphates in vitro when bicalcium phosphate was used as a phosphorus source. this strain was gram-negative, strictly aerobic, rod-shaped and motile. the strain produced catalase, but not oxidase. cellulose, casein, starch, gelatin, aesculin and urea were not hydrolysed. growth was observed with many carbohydrates as the carbon source. the main non-polar ... | 2003 | 14657147 |
| complete genome sequence of pseudomonas rhizosphaerae ih5t (=dsm 16299t), a phosphate-solubilizing rhizobacterium for bacterial biofertilizer. | pseudomonas rhizosphaerae ih5(t) (=dsm 16299(t)), isolated from the rhizospheric soil of grass growing in spain, has been reported as a novel species of the genus pseudomonas harboring insoluble phosphorus solubilizing activity. to understanding the multifunctional biofertilizer better, we report the complete genome sequence of p. rhizosphaerae ih5(t). | 2015 | 25483321 |
| pseudomonas coleopterorum sp. nov., a cellulase-producing bacterium isolated from the bark beetle hylesinus fraxini. | we isolated a strain coded esc2am(t) during a study focused on the microbial diversity of adult specimens of the bark beetle hylesinus fraxini. its 16s rrna gene sequence had 99.4% similarity with respect to its closest relative, pseudomonas rhizosphaerae ih5(t). the analysis of partial sequences of the housekeeping genes rpob, rpod and gyrb confirmed that strain esc2am(t) formed a cluster with p. rhizosphaerae ih5(t) clearly separated from the remaining species of the genus pseudomonas. strain ... | 2015 | 25999590 |
| effects of illuminance and nutrients on bacterial photo-physiology of hydrocarbon degradation. | bacterial photophysiology was previously limited to photoautotrophs. the discovery of bacteriophytochromes in non-photoautotrophs raised a question whether these non-photoautotrophs are affected by the presence or absence of light? in this research work for the first time, bacterial hydrocarbon degradation and biomass production was studied under the influence of nutrients, illuminance (light flux) and time. an experimental model was designed, with six isolated bacterial strains (pseudomonas poa ... | 2016 | 27039061 |
