  abstract = {{S}oil aggregates and particulate organic matter ({POM}) are thought to represent distinct soil microhabitats for microbial communities. {T}his study investigated whether organo-mineral (0-20,20-50 and 50-200 pm) and {POM} (two sizes: >200 and <200 mu m) soil fractions represent distinct microbial habitats. {M}icrobial habitats were characterised by the amount and quality of organic matter, the genetic structure of the bacterial community, and their location outside or inside macroaggregates (>200 mu m). {T}he denaturing gradient gel electrophoresis ({DGGE}) profiles revealed that bacterial communities structure of organo-mineral soil fractions were significantly different in comparison to the unfractionated soil. {C}onversely, there were little differences in {C} concentrations, {C}:{N} ratios and no differences in {DGGE} profiles between organo-mineral fractions. {B}acterial communities between soil fractions located inside or outside macroaggregates were not significantly different. {H}owever, the bacterial communities on {POM} fractions were significantly different in comparison to organo-mineral soil fractions and unfractionated soil, and also between the 2 sizes of {POM}. {T}hus in the studied soil, only {POM} fractions represented distinct microhabitats for bacterial community, which likely vary with the state of decomposition of the {POM}.},
