Microbial utilization of estuarine dissolved organic carbon: a stable isotope tracer approach tested by mass balance
Article Abstract:
The mass balance method, based on mass and stable isotope analyses accurately determines the dissolved organic carbon (DOC) source that supports microbial growth in estuaries. Bacteria convert 25% to 80% of the delta 13C-DOC obtained from the estuarine plants Spartina alterniflora and Typhus angustifolia into their biomass and CO2. The stable isotope content of the bacteria is similar to that of the carbon source. The values of delta 13C in the DOC, CO2 and bacterial biomass show negligible variation as compared to the variation in the delta 13C values of different carbon sources.

Population dynamics of polychlorinated biphenyl-dechlorinating microorganisms in contaminated sediments
Article Abstract:
The factors that control the growth of polychlorinated biphenyl (PCB)-dechlorinating microorganisms were analyzed based on the most-probable-number (MPN) technique. Analysis of the population dynamics of PCB dechlorinators based on the MPN technique indicated the importance of PCBs in the growth of the microbes. Furthermore, the reductive dechlorination of 3-chlorobenzoate in the microbial cultures indicated the ability of the PCB-dechlorinating microbes to degenerate energy from aerobic respiration.

Growth and multiplexed analysis of microorganisms on a subdivided, highly porous, inorganic chip manufactured from Anopore
Article Abstract:
A highly porous inorganic material (Anopore) is an effective support for culturing and imaging a wide range of microorganisms. An inert barrier grid is printed on the rigid surface of Anopore to create a 'living chip' with broad applications in microbial culture.
