The majority of bacteria suspended in seawater do not appear to be metabolically active or in good physiological condition as assessed by various methods. We tested the idea that a large fraction of 'inactive' bacterial cells can become 'active' with respect to detectable cell-specific electron transport system (ETS) activity, determined by the ability of cells to reduce the fluorogenic tetrazolium salt, CTC, when incubated for periods of time with or without additional substrate.

Coherence of microbial respiration rate and cell-specific bacterial activity in a coastal planktonic community
TLDR
Both abundance and proportion of CTC-active cells were highly correlated with respiration rates within the microplankton community (c3 pm size fraction), explaining 80%, or more, of the variations in these rates.
Are the actively respiring cells (CTC+) those responsible for bacterial production in aquatic environments?
TLDR
It is clearly demonstrated that the CTC method is not valid to detect active bacteria, i.e. cells responsible for bacterial production.
Estimating abundunce and single-cell characteristics of respiring bacteria via the redox dye CTC
The redox dye 5-cyano-2,3-ditolyl tetrazolium chloride (CTC) is used in aquatic sciences as a vital stain for enumeration of respiring bacteria in situ. Questions concerning its efficacy have been
Single‐cell physiological structure and growth rates of heterotrophic bacteria in a temperate estuary (Waquoit Bay, Massachusetts)
TLDR
Positive correlations of HNA bacteria µ with total and phytoplankton‐derived dissolved organic carbon support the previously hypothesized strong bottom‐up control of H NA cells.
Daily variations of highly active bacteria in the Northern Adriatic Sea
TLDR
The results suggest that freshwater inputs rather than phytoplanktonic blooms are able to induce shifts in bacterial metabolism over a time scale of days in the area studied.
Metabolically active bacteria in Lake Kinneret
TLDR
The hypothesis that in natural waters usually only a small portion of the entire bacterial assemblage is strongly active metabolically at any given time is supported, as some bacteria which initially appear to be inactive can become active when stimulated by substrate addition, even though cell division is inhibited.
Large Differences in the Fraction of Active Bacteria in Plankton, Sediments, and Biofilm
TLDR
Compared the active fraction of the total number of bacteria in three different habitats of the littoral zone of Lake Erken, Sweden, including the sediments, the epiphytic biofilm on the submerged macrophyte Ranunculus circinatus, and the water column, there were large differences between habitats.
Physiological Structure and Single‐Cell Activity in Marine Bacterioplankton
TLDR
It was not until bacteria were recognized as being not only very abundant, but also active, that the notion of microbes as important partners in the marine food web gained widespread recognition and early studies using radiotracer incorporation showed surprisingly high rates of bacterial activity.

Relation between presence‐absence of a visible nucleoid and metabolic activity in bacterioplankton cells
TLDR
Results show that some bacteria without visible nucleoids are capable of becoming NV cells, and thus have DNA in a nucleoid region not detectable with the method used here.
Active versus inactive bacteria: size-dependence in a coastal marine plankton community
TLDR
The results support the hypothesis of Stevenson (1978, Microb Ecol 4:127-133) that very small bacteria are mainly dormant (inactive) while bigger bacteria are more likely to be active and suggest that phagotrophic protists will preferentially crop the active portion of the bacterial community if they select their prey according to size.

Total counts of marine bacteria include a large fraction of non-nucleoid-containing bacteria (ghosts)
TLDR
In samples from the Baltic Sea, the North Sea, and the northeastern Mediterranean Sea, it is found that only a minor fraction of total counts can be scored as bacteria with nucleoids; therefore, a much lower number of bacteria that grow at rates higher than those previously estimated must be responsible for the measured bacterial production in these seas.
Determination of Active Marine Bacterioplankton: a Comparison of Universal 16S rRNA Probes, Autoradiography, and Nucleoid Staining
TLDR
Universal 16S rRNA probe counts correlated well with autoradiography results, indicating a population with at least minimal metabolic activity in marine waters and the greater variability of the nucleoid-containing cell counts calls for further investigation of the processes involved.
Simultaneous determination of the total number of aquatic bacteria and the number thereof involved in respiration
TLDR
Initial applications of the present method for hydrobiological purposes showed that the proportion of respiring aquatic bacteria ranged between 6 to 12% (samples taken from coastal areas of the Baltic Sea) and 5 to 36% (sampled taken from freshwater lakes and ponds).
Cell-specific respiratory activity of aquatic bacteria studied with the tetrazolium reduction method, cyto-clear slides, and image analysis
TLDR
There was no correlation between the total formazan volume per active cell and bacterial cell volume, and for any size class of active bacteria, total formAZan volumes varied by about 2 orders of magnitude after 8 h of incubation, which indicates that cell-specific activity is extremely variable and is not related to size.
Direct Determination of Activities for Microorganisms of Chesapeake Bay Populations
TLDR
Active rather than dormant organisms compose a major portion of the microbial population in this region of Chesapeake Bay, with significant dependence on in situ water temperature, independent of the function of temperature on total counts.
Ecological implications of an improved direct viable count method for aquatic bacteria
TLDR
The direct viable count method first described by Kogure et al. was improved by using an antibiotic cocktail instead of nalidixic acid alone, which resulted in an increased incubation time and were related to metabolic expression of slow-growing cells and/or to the recovery of starved cells.
