説明

The finding that most strains of microbes produce a growth stimulating substance for microorganisms was demonstrated and confirmed with the culture broth of Escherichia coli grown on a glucose-mineral medium. Addition of culture broth of E. coli to the culture media of the others markedly reduced the lag phase in microbial growth but not growth rate in the subsequent exponential phase nor the total cell yield in the stationary phase. The growth stimulation causing reduction of the lag phase was dependent on the amount of culture broth added. Occurrence of cell growth was essential for the excretion of the growth stimulating substance by E. coli. Under identical inoculum size, even with a heavy inoculum, a further reduction of the lag phase was observed by the addition of culture broth of E. coli. The substance was only effective at the initial growth phase but inert when the substance was added to a growing culture at the exponential phase. Finally, the substance was identified as pyrroloquinoline quinone, a newly established coenzyme, through chromatographic, spectroscopic and enzymatic criteria.
