Bacterial growth in artificial capillary spaces

Summary In experiments on the influence of microscopic capillaries on the growth ofEscherichia coli, Brevibacterium linens, Micrococcus flavus andBacillus cereus, a distinet delay in growth was observed. The difference in counts was greatest after 8 h. Later a slight equilibration of counts was noted. WithB. cereus, only slight or no spore formation was observed under microcapillary conditions.Acknowledgment. The author would like to thank Mr. Theo Wihan for his excellent technical assistance.
