||Researchers used flow cytometry to determine the cell cycle periods
C and D in steady-state batch cultures of seven strains of
E. coli K-12 and three of E. coli B/r (Table link). The different
generation times were obtained by using different carbon
sources. Flow cytometry can obtain multiparametric measurements of thousands of microscopic particles such as cells or chromosomes suspended in a stream of fluid per second.
||DNA distributions obtained by flow cytometry were resolved with
researchers' computer software into the cell cycle periods C, D and B. Generation time range 21min (LJ24)-450min(FH1228). C period 39min (RH147)-105min (MG1655). B period-time between division time and initiation of replication of chromosome. C period range - time to replicate chromosome. D period-time between termination of replication and division time.
