Stratification of activity and bacterial community structure in biofilms grown on membranes transferring oxygen
Article Abstract:
The unique stratification of membrane-aerated biofilms (MABs) in relation to bacterial community structure and function was characterized. Result indicates that the bacterial community structure and activity in MABs is stratified as a function of biofilm depth and there exists a possibility of the coexistence between ammonia-oxidizing bacteria (AOB) and denitrifying bacteria in an MAB.

Denitrifier community composition along a nitrate and salinity gradient in a coastal aquifer
Article Abstract:
A study was conducted to examine the diversity and composition of denitrifying bacteria that vary across environmental gradients in both nitrate and salinity within an unconfined beach aquifer. The findings suggest that diversity in these enzymes results from adaptation to a particular environment rather than just random microheterogeneity alone.

Characterization of growing microorganisms in soil by stable isotope probing with [H.sub.2][super 18]O
Article Abstract:
A new approach is described for characterizing growing microorganisms in environmental samples based on labeling microbial DNA with [H.sub.2][super 18]O. Labeling soil DNA with [H.sub.2][super 18]O has allowed the identification of newly grown cells.
