Conversion factors relating thymidine uptake to growth rate with rhizosphere bacteria
Chapter
Abstract
Growth rates of some rhizosphere bacteria can be measured by the use of 3H-thymidine (3H-TdR) labelling. However fluorescent pseudomonads of soil origin were found to incorporate little or no 3H-TdR into DNA. The conversion factor relating cellular growth rate to 3H-TdR incorporation for exponentially growing cultures of non-pseudomonads was about 2 × 1018 cells mole TdR-1. This value is comparable to constants used in aquatic environments.
