Achouak W, Thiéry JM, Roubaud P, Heulin T.
PMID: 10620714
FEMS Microbiol Ecol. 2000 Jan 01;31(1):11-19. doi: 10.1111/j.1574-6941.2000.tb00666.x.

The genetic structure of Pseudomonas corrugata populations was investigated in bulk soil to evaluate the impact of crop management on the intraspecific diversity of this bacterium stimulated in plant rhizosphere. As these bacteria are rare in bulk soil, an...

Nitrate-limited batch cultures, incorporating 20 different fermentation substrates and inoculated with human faeces, mainly selected for the growth of enterobacteria. The microbial diversity involved was determined by a combination of phenotypic and genotypic procedures. Continuous culture with lactate as...

PMID: 10620720
FEMS Microbiol Ecol. 2000 Jan 01;31(1):61-71. doi: 10.1111/j.1574-6941.2000.tb00672.x.

Molecular tools for the detection of the newly described acetic acid bacterium Gluconacetobacter sacchari from the pink sugarcane mealybug, Saccharicoccus sacchari Cockerell (Homiptera: Pseudococcidae), and in the sugarcane leaf sheath microenvironment were developed. G. sacchari specific 16S rRNA-targeted oligonucleotide...

Pattern of non-methanogenic and methanogenic degradation of cellulose in anoxic rice field soil.

FEMS microbiology ecology

Chidthaisong A, Conrad R.
PMID: 10620722
FEMS Microbiol Ecol. 2000 Jan 01;31(1):87-94. doi: 10.1111/j.1574-6941.2000.tb00674.x.

Rice field soils turn anoxic upon flooding. The complete mineralization of organic matter, e.g. cellulose, to gaseous products is then accomplished by the sequential reduction of nitrate, ferric iron, sulfate and finally by methanogenesis. Therefore, the anaerobic turnover of...

Selective inhibition of reactions involved in methanogenesis and fatty acid production on rice roots.

FEMS microbiology ecology

Conrad R, Klose M.
PMID: 11053733
FEMS Microbiol Ecol. 2000 Oct 01;34(1):27-34. doi: 10.1111/j.1574-6941.2000.tb00751.x.

Washed excised roots of rice (Oryza sativa) produced H(2), CH(4) and fatty acids (millimolar concentrations of acetate, propionate, butyrate; micromolar concentrations of isovalerate, valerate) when incubated under anoxic conditions. Surface sterilization of the root material resulted in the inactivation...

Fitness in soil and rhizosphere of Pseudomonas fluorescens C7R12 compared with a C7R12 mutant affected in pyoverdine synthesis and uptake.

FEMS microbiology ecology

Mirleau P, Delorme S, Philippot L, Meyer J, Mazurier S, Lemanceau P.
PMID: 11053734
FEMS Microbiol Ecol. 2000 Oct 01;34(1):35-44. doi: 10.1111/j.1574-6941.2000.tb00752.x.

Fluorescent pseudomonads have evolved an efficient strategy of iron uptake based on the synthesis of the siderophore pyoverdine and its relevant outer membrane receptor. The possible implication of pyoverdine synthesis and uptake on the ecological competence of a model...

Detection of Desulfotomaculum in an Italian rice paddy soil by 16S ribosomal nucleic acid analyses.

FEMS microbiology ecology

Stubner S, Meuser K.
PMID: 11053738
FEMS Microbiol Ecol. 2000 Oct 01;34(1):73-80. doi: 10.1111/j.1574-6941.2000.tb00756.x.

Two specific primers were developed for the amplification of 16S rRNA genes of Desulfotomaculum lineage 1 to detect members of the genus Desulfotomaculum in rice field soil. The combination of both primers in PCR allowed the specific amplification and...

Detection and distribution of insertion sequence 1 (IS1)-containing bacteria in the freshwater environment(1).
