Bacterial growth in artificial capillary spaces

In experiments on the influence of microscopic capillaries on the growth of Escherichia coli, Brevibacterium linens, Micrococcus flavus and Bacillus cereus, a distinct delay in growth was observed. The difference in counts was greatest after 8 h. Later a slight equilibration of counts was noted. With B. cereus, only slight or no spore formation was observed under microcapillary conditions.
