Description of the Book:

With regard to the tests made with grampositive bacteria, B cereus and B subtilis became plasmolyzed in 1.0-mol. cane sugar and KNO3 solutions. It seems that the established non-plasmolyzability of gram-positive bacteria is caused by a tighter than usual cohesion of protoplast and cell membrane rather than by any great permeability of such cell membrane. The test results on B subtilis show that saccharose, glucose, and mannitol do not seem to permeate in detectable quantities into the cells during the test period of 40 minutes; in other words, it would appear that the cells of B subtilis are much less permeable to saccharose, glucose, and mannitol than the examined gram-negative bacteria
