Bacterial growth and community composition in fractions of dissolved organic carbon of different molecular weights from interstitial water.

Original language description

The ability of different molecular weight fractions of interstitial dissolved organic carbon (DOC) from a small stream to stimulate bacterial growth was tested. Bacterial growth was greatest in the low-molar mass (LMM) fraction (1000 Da) and least in thehigh-molar mass (HMM) fraction (10 000 Da). The LMM fraction consistently had the higher C/Norganic then other fractions. The fluorescence in situ hybridization analysis revealed that bacterial populations in interstitial water were dominated by -Proteobacteria. The -Proteobacteria together with Cytophaga-Flavobacteria cluster dominated in LMM DOC (66.3 %) while the proportions of bacterial groups in HMM and medium-molar mass (MMM) fractions were more equal. The -Proteobacteria strongly dominating in LMM DOC fraction refute the idea that LMM DOC is readily utilized by all heterotrophic bacteria.
