Adsorption of bacteriophages phi 29 and 22a to protoplasts of Bacillus subtilis 168. 1977

E D Jacobson, and O E Landman

Adsorption of bacteriophages phi 29 and 22a to protoplasts of Bacillus subtilis 168 is described. The number of binding sites on bacilli and protoplasts is determined for each phage. Bacilli and protoplasts possess roughly the same number of sites per unit area for phi 29, i.e., approximately 700 sites per bacillus. There are also approximately 700 sites per bacillus for 22a, but only about one-third as many sites per unit area on the protoplast surface. A model for phi 29 adsorption is proposed.

D011523	Protoplasts	The protoplasm and plasma membrane of plant, fungal, bacterial or archaeon cells without the CELL WALL.	Protoplast
D002473	Cell Wall	The outermost layer of a cell in most PLANTS; BACTERIA; FUNGI; and ALGAE. The cell wall is usually a rigid structure that lies external to the CELL MEMBRANE, and provides a protective barrier against physical or chemical agents.	Cell Walls,Wall, Cell,Walls, Cell
D000327	Adsorption	The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily.	Adsorptions
